Abstract
Description
BACKGROUND
[0001] Conventional approaches to automatic labeling and segmentation tools rely on existing data sets, which can not generate robust tools for various applications due to lack of data from different domains. For example, existing training data sets can not include specific environments, object orientations, or other characteristics of the deployment environment for a particular automatic labeling or segmentation tool. Furthermore, obtaining annotations and masks for training data sets is both time consuming and error prone. Moreover, convolutional neural networks (CNNs) for object detection and other tasks typically work best when partitioned into rectangular boxes whose edges are parallel to the boundaries of the images provided to the CNN, which can create a domain gap in various practical applications. Existing automatic labeling and segmentation tools are limited by existing training data sets, which are costly and difficult to generate. Furthermore, these tools require human supervision during training. BRIEF DESCRIPTION OF DRAWINGS

[0059] Embodiments of this disclosure relate to rotationally robust automatic labeling tools for segmentation. Systems and methods are disclosed that provide a self-training method to obtain a segmentation mask (e.g., for a pedestrian detection task) from bounding boxes generated by a first model. A second model can then use the obtained segmentation mask to generate tighter (more compact) bounding boxes in the rotated image, which can be used as additional enhancements to generate ground-realistic bounding boxes (e.g., non-axis-aligned bounding boxes) for objects in the image, and / or to generate segmentation labels for objects. Rotation is one example of modification that, in various embodiments, can be applied to a training dataset (e.g., a curated and annotated set of images) to increase the robustness of the trained model and reduce domain gaps. Domain gaps describe the difference between the environment captured in the training dataset and the environment in which the trained model is deployed (e.g., trained using the training dataset). Other examples of modifications to the training dataset used in this disclosure include modifications to brightness, contrast, scale, rotation, orientation, or other modifications to the training dataset to simulate the environment in which the trained model generates inference.
[0060] Compared to traditional systems (as described above), the systems and methods described in this disclosure do not require human interaction (e.g., self-training methods) and can be used with existing training datasets. In other words, the systems and methods described in this disclosure eliminate the costs and errors associated with requiring human intervention and can be implemented using existing training datasets, thereby eliminating the need and cost of generating training datasets. For example, models trained using the systems and methods described in this disclosure (e.g., convolutional neural networks) are robust to rotation, occlusion, truncation, or other forms of obstacles to objects in images or videos.
[0061] In one embodiment, a two-stage self-trained automatic labeling tool is used to obtain segmentation and / or annotation based at least in part on bounding boxes of a set of images. In this embodiment, during the first stage, a model is trained using a training dataset to generate preliminary mask annotations for either the training dataset or another training dataset. In one example, a mask region-based convolutional neural network (Mask R-CNN) is trained using a first dataset (e.g., common objects in a background dataset), and then the Mask R-CNN is used to generate preliminary mask annotations for a second training dataset. Furthermore, in this example, since the training dataset includes bounding boxes of objects in the images, Mask R-CNN is performed without a region proposal network. In various embodiments, the preliminary mask annotations and the second training dataset are subsequently used to train a new model or retrain the aforementioned Mask R-CNN model, thereby producing the pre-labeled tool used in the second stage.
[0062] During the second phase, in one embodiment, a new model (e.g., a new masked R-CNN model) is trained using a second training dataset, which includes bounding boxes and segmentations generated by a pre-labeling tool produced in the first phase. Furthermore, in various embodiments, the second training dataset is modified. In one example, images from the training dataset are rotated (e.g., 5 degrees clockwise), and then coarse bounding boxes are generated around objects in the training dataset images using the pre-labeling tool, while finer bounding boxes are generated around the objects in the images using the new model (e.g., the model trained in the second phase). In this way, additional training data can be generated to expand the training dataset and reduce any domain gaps.
[0063] refer to Figure 1 , Figure 1 This is an example training method according to some embodiments of the present disclosure for training a pre-labeling tool 108 for training a neural network for segmentation rotation robustness. It should be understood that such and other arrangements described herein are merely illustrative examples. Other arrangements and elements (e.g., machines, interfaces, functions, commands, function groups, etc.) may be used to supplement or replace the arrangements and elements shown, and some elements may be omitted entirely. Furthermore, many of the elements described herein are functional entities that can be implemented as discrete or distributed components, or in combination with other components, and can be implemented in any suitable combination and location. The various functions performed by the entities described herein can be performed by hardware, firmware, and / or software. For example, various functions can be performed by a processor executing instructions stored in memory.
[0064] Now for reference Figure 1 , 2In sections 100, 200, and 500, each block of methods 100, 200, and 500 described herein includes a computational process that may be performed using any combination of hardware, firmware, and / or software. The various functions and / or operations described in this disclosure can be performed by a processor executing instructions stored in memory. In one example, dataset 102 includes a collection of annotated images stored in a storage device such as a hard disk drive (HDD). In another example, inference neural network 104 includes source code stored in the memory of a computer system, which, when executed by the processor of the computer system, causes the computer system to perform inference operations, as described in more detail below. The methods can also be implemented as computer-usable instructions stored on a computer storage medium. These methods can be provided by standalone applications, services, or managed services (standalone or in combination with another managed service) or plug-ins to another product, to name a few. Furthermore, as an example, for... Figure 12 Methods 100, 200, and 500 are described in the computer systems described herein. However, these methods may be performed additionally or alternatively by any system or any combination of systems, including but not limited to the systems described herein.
[0065] Back Figure 1 , Figure 1 This is a flowchart illustrating a method 100 for generating a pre-labeled tool 108 according to some embodiments of the present disclosure. Method 100 includes a dataset 102, which in various embodiments includes images 110 and bounding boxes 112 depicting various objects and / or object categories (e.g., people, cars, clothing, animals, etc.). In one embodiment, the bounding box 112 includes metadata or other information associated with the images 110 of the dataset 102 that defines a rectangle or other geometry that surrounds (e.g., creates a boundary around) a specific object included in the images of the dataset 102. For example, the bounding box 112 includes a minimum (e.g., minimum area) or perimeter bounding box around an object in the image, wherein all pixels depicting the object lie within the boundary created by the bounding box. In various embodiments, the dimension of the bounding box 112 is N, where N is the total number of dimensions depicted in the images 110 of the dataset 102. For example, the dataset 102 may include a 3D image 110, an image 110 including video, a 2D image 110, or other images suitable for training a neural network or performing inference using a neural network.
[0066] In various embodiments, dataset 102 includes a curated dataset that incorporates segmentation and annotation information (e.g., bounding boxes 112) at least in part based on human-generated segmentation and annotation information. In one example, dataset 102 includes a common object (COCO) dataset in context. In other embodiments, the segmentation and annotation information (e.g., bounding boxes 112) is generated by a model such as a neural network.
[0067] Back Figure 1 Images 110 from dataset 102 are fed to inference neural network 104 to generate preliminary mask annotations 114. In one embodiment, inference neural network 104 is a trained network for detecting objects and / or object categories depicted in image 110. In various embodiments, inference neural network 104 includes any neural network trained to perform image segmentation and annotation. In one example, inference neural network 104 is trained using dataset 102. In another example, inference neural network 104 is trained using a dataset separate from dataset 102.
[0068] In various embodiments, the inference neural network 104 includes a mask-based convolutional neural network (R-CNN) or other convolutional neural network adapted to generate coarse segmentation information for objects in image 110 for training the training neural network 106. In various embodiments, the image 110 provided to the inference neural network 104 does not include segmentation and / or annotation information (e.g., bounding boxes 112). In one embodiment, preliminary mask annotation 114 includes bounding boxes and / or masks for objects and / or a class of objects (e.g., people) depicted in image 110. Figure 3 The preliminary mask is described in more detail below (note 114).
[0069] In various embodiments, the training neural network 106 includes any neural network capable of being trained using segmentation and annotation information. In one example, the training neural network 106 is a masked R-CNN without a region proposal network module. Furthermore, as... Figure 1 As shown in the illustrated embodiments, a training neural network 106 is trained using dataset 102 (including bounding boxes 112) and preliminary mask annotations 114 generated at least partially by an inference neural network 104. In various embodiments, a pre-labeling tool 108 is generated as a result of training the neural network 106 as described above. In one embodiment, the pre-labeling tool 108 is a trained neural network that generates fine-grained segmentations (e.g., masks) and annotations for images of a dataset (e.g., dataset 102) when inference is performed on an input (e.g., an image). In various embodiments, the pre-labeling tool 108 includes software, hardware, or a combination thereof that utilizes a neural network or other model to perform various operations, such as performing inference to generate masks, generate bounding boxes, or other operations described in this disclosure. As described in more detail below, the pre-labeling tool 108 can be used to generate segmentations and annotations for a modified dataset. In one example, images 110 of dataset 102 are rotated or otherwise modified to generate an environment-robust training model.
[0070] Figure 2This is a flowchart illustrating a method 200 for generating a trained neural network 208 according to some embodiments of the present disclosure, the trained neural network 208 being robust to rotation, occlusion, truncation, or other forms of obstruction or blurring of objects in an image or video. In various embodiments, the method 200 for training the trained neural network 208 includes a dataset 202. For example, dataset 202 includes the above-described... Figure 1 The dataset 202 describes a set of images depicting the object (e.g., a curated set of images including bounding boxes and annotations). Furthermore, in various embodiments, the dataset 202 includes modifications and / or alterations to the set of images included in the dataset 202. In such embodiments, the modifications and / or alterations to the set of images augment the dataset 202 by generating at least modified images 210 to reduce the domain gap between the set of images in the dataset 202 and the target domain of the trained neural network 208, enabling the trained neural network 208 to produce better results during inference.
[0071] In one embodiment, dataset 202 is augmented by rotating at least one set of images around the optical axis to generate modified image 210. For example, the set of images is rotated 5 degrees clockwise to generate modified image 210. Furthermore, in various embodiments, modified image 210 is used during the training of neural network 206, which is described in more detail below. In another example, the brightness values associated with image 210 are modified to generate modified image 210.
[0072] Furthermore, in various embodiments, multiple modifications and / or alterations are performed on the set of images to generate a modified image 210 to augment the dataset 202. In one example, the set of images is rotated 5 degrees clockwise and 10 degrees clockwise to generate the modified image 210 (e.g., the modified image 210 comprises images of the set of images rotated 5 and 10 degrees). In one embodiment, multiple types of modifications or alterations are applied to the set of images to generate the modified image 210. For example, the set of images is rotated, and the scale associated with the set of images is modified. These modifications and / or alterations can be performed individually or in combination. Furthermore, the modifications and / or alterations can be applied to the set of images sequentially or in parallel.
[0073] As described above, modifications and / or alterations to a set of images may include a variety of different operations, such as rotation, flipping, cropping, modifying exposure, modifying white balance, modifying color, modifying saturation, sharpening images, applying filters, modifying scale, or otherwise modifying, adjusting, or otherwise altering a set of images to represent the environment in which the trained neural network 208 performs inference.
[0074] Back Figure 2In various embodiments, the modified image 210 is provided to a pre-labeling tool 208, which generates more refined mask annotations 214 for the objects depicted in the modified image 210. In one embodiment, the pre-labeling tool 208 uses the combination of the above... Figure 1 The described method 100 trains a neural network or other model. For example, the pre-labeling tool 208 is a masked R-CNN trained using a dataset (e.g., dataset 102) that includes bounding boxes and annotations. In one embodiment, it is combined with the following... Figure 4 In more detail, the pre-labeling tool 208 generates finer mask annotations 214 for specific categories of objects and / or categories in the modified image 214. In various embodiments, the finer mask annotations 214 include additional data and / or metadata identifying pixels in the modified image 210 that depict specific objects and / or object categories. In one example, the modified image 210 includes a set of images depicting people (e.g., pedestrians) in the background, rotated around an optical axis by a set of values. The pre-labeling tool 208 then generates finer mask annotations 214 that identify pixels in a set of images that include people and markers that identify pixels as associated with people. As described above, in some examples, the rotation of the images around the optical axis results in inaccurate and / or incorrect bounding boxes and other segmentation information associated with dataset 202. In such examples, the pre-labeling tool 208 generates finer mask annotations 214 that provide accurate segmentation information for training the neural network 206.
[0075] In various embodiments, the training neural network 206 includes any neural network capable of being trained using segmentation and annotation information (e.g., more refined mask annotations 214). In one example, the training neural network 206 is a mask R-CNN trained using a dataset 202 that includes modified images 210 and more refined mask annotations 214. Furthermore, as... Figure 2 As illustrated in the depicted embodiments, a trained neural network 208 is obtained when the neural network 206 is trained using dataset 202 (which includes bounding boxes, a modified image 210, and more refined mask annotations 214). In various embodiments, the trained neural network 208 is a trained model that is robust to its environment and capable of recognizing objects or object categories depicted in an image. For example, as a result of rotating images from the dataset to generate the modified image 210, the trained neural network 208 is able to detect objects in the image regardless of the image's optical angle (e.g., camera angle). In another example, the trained neural network 208 is able to detect objects in a low-light image due to the reduction of brightness values associated with images in the dataset.
[0076] Figure 3This is an illustration of an image 300 including a preliminary mask annotation 302 according to at least one embodiment described in this disclosure. In various embodiments, the preliminary mask annotation 302 is generated by a trained model, for example, in conjunction with the above. Figure 1 The inference neural network 104 is described.
[0077] like Figure 3 As shown, image 300 includes preliminary mask annotations 302 for a person depicted in image 300. Although image 300 and preliminary mask annotations 302 include a person, an inference neural network can be trained to generate preliminary mask annotations 302 for any object or object category. Furthermore, in various embodiments, preliminary mask annotations 302 include various types of segmentation information, such as bounding boxes, masks, markers, annotations, or other information suitable for identifying objects in the image. Additionally, although... Figure 3 Image 300 is depicted, but preliminary mask annotation 302 may be generated for three-dimensional representation, four-dimensional representation, video, or other media capable of depicting objects.
[0078] In some examples, the preliminary mask annotation 302 is included within the image 300 as supplementary data. In other examples, the preliminary mask annotation 302 is supplementary data provided along with the image (e.g., as annotations provided to the neural network). Furthermore, as described above, the preliminary mask annotation 302 may include coarse annotations generated by a neural network trained using a selected dataset. In various embodiments, the preliminary mask annotation 302 is used to train the neural network, such as the pre-labeling tool 208 described above.
[0079] Figure 4 This is an illustration of an image 400 including a more refined mask annotation 402, according to at least one embodiment described in this disclosure. The more refined mask annotation 402 is generated by a trained model, such as those described above. Figure 1 The pre-labeling tool 108 is described. (For example...) Figure 3 As shown, image 400 includes more refined mask annotations 402 for the people depicted in image 400. In various embodiments, the more refined mask annotations 402 are generated by a pre-labeling tool for images in a dataset used to train the pre-labeling tool. Furthermore, as described above... Figure 2 The description suggests that images in the dataset may be modified, and more refined mask annotations 402 may be generated, at least in part, based on the modified images. Although image 400 and the more refined mask annotations 402 include people, the inference neural network can be trained to generate more refined mask annotations 402 for any object or object category. Furthermore, in various embodiments, the more refined mask annotations 402 include various types of segmentation information, such as bounding boxes, masks, labels, annotations, or other information suitable for recognizing objects in the image. Additionally, although... Figure 4Image 400 is depicted, but more detailed mask annotations 402 may be generated for 3D images, 4D images, videos, or other media capable of depicting objects.
[0080] In some examples, finer mask annotations 402 are included within image 400 as additional data. In other examples, finer mask annotations 402 are additional data provided along with the image (e.g., as annotations to the image provided to the neural network). In various embodiments, finer mask annotations 402 are used to train neural networks, such as the trained neural network 208 described above.
[0081] Figure 5 This is a flowchart illustrating a method 500 for generating a trained neural network robust to rotation, occlusion, truncation, other forms of obstacles, or other environmental factors in an image or video, according to some embodiments of the present disclosure. In various embodiments, the method 500 for training the neural network includes two training phases: a first training phase 502 and a second training phase 504. Furthermore, in one example, the first training phase 502 includes method 100 as described above, and the second training phase includes method 200 as described above. During the first training phase 502, in block 506, the system performing method 500 performs inference on a dataset using a neural network. As described above, the neural network may include a mask R-CNN trained at least in part on a selected dataset (which may differ from the dataset used to perform the inference). Furthermore, in various embodiments, in block 508, pseudo-mask segmentation is generated as a result of performing inference on the dataset using the neural network. For example, the pseudo-mask segmentation generated by the neural network may include preliminary mask annotations as described above.
[0082] In various embodiments, in the second training phase 504 of box 510, the second neural network is trained at least in part based on pseudomask segmentation and the dataset. As described above, in various embodiments, the dataset is augmented or otherwise expanded by modifying it (e.g., images or videos included in the dataset). For example, images in the dataset are modified, and segmentation data (e.g., masks) is generated for the modified dataset, which is then used to train the neural network. In box 508, the trained neural network is used to generate more refined pseudomask segmentation. In one embodiment, more refined pseudomask segmentation includes the above-described combination of... Figure 4 More refined mask annotations are described. Furthermore, in various embodiments, more refined pseudo-mask segmentation is used to train additional models robust to various environmental factors captured by modifying the dataset by at least the above description.
[0083] Figure 6This is an illustration of a modified image 600 including coarse and fine annotations, according to at least one embodiment described in this disclosure. In the various embodiments described above, images, videos, or other information included in a dataset are modified and used to train an environment-robust model. Figure 6 As shown, the modified image 600 includes an image rotated about an axis. Although Figure 6 The image shown is a rotated modified image, but any number of additional and / or alternative modifications can be applied to the image to generate a modified image as described in more detail above.
[0084] In the various embodiments described above, the first trained neural network generates coarse bounding boxes 602 for objects in the modified image. In one example, the coarse bounding box 602 includes preliminary mask annotations as described above. In another example, the coarse bounding box is generated as a result of not training the neural network in the manner described above to generate a rotation-robust neural network. In such an example, as... Figure 6 As shown, the coarse bounding box 602 includes additional pixels that do not correspond to the person depicted in the modified image 600. In various embodiments, the fine bounding box 604 of the modified image 600 is generated by a pre-labeling tool as described above. Furthermore, in one embodiment, the fine bounding box 604 is used to train a rotation-robust neural network.

[0087] Figure 7 This is a flowchart illustrating a method 700 for generating a pre-labeled tool according to some embodiments of the present disclosure. At block B702, method 700 includes obtaining a dataset including bounding box information. In various embodiments, the dataset includes images depicting various objects and / or object categories (e.g., people, cars, clothing, animals, etc.), and bounding boxes corresponding to these objects. For example, the dataset includes a Common Objects in Background (COCO) dataset, which includes bounding boxes. In one embodiment, the bounding boxes include metadata or other information defining a rectangle or other geometry associated with an image of the dataset that surrounds a specific object included in the dataset image. For example, the bounding box includes a minimum perimeter bounding box around an object in the image, wherein all pixels depicting the object are within the bounding box. In various embodiments, the bounding box information also includes segmentation information, annotations, or other information suitable for training a model to perform object detection, labeling, or similar tasks. In one embodiment, the bounding box information is generated by a trained model performing inference on images included in the dataset.
[0088] Back Figure 7In box B704, the system executing method 700 performs inference on the dataset to generate preliminary mask annotations. For example, a trained neural network performs inference to detect objects and / or a class of objects depicted in the images. In one embodiment, the neural network is trained on a second dataset different from the dataset described above. In various embodiments, the inference neural network includes any neural network trained to perform image segmentation and annotation. In one example, the inference neural network is trained using the dataset and bounding box information. For example, the inference neural network includes a mask region-based convolutional neural network (R-CNN) or other convolutional neural networks suitable for generating coarse segmentation information for objects in an image. In various embodiments, the images provided to the inference neural network do not include segmentation and / or annotation information (e.g., bounding box information). In one embodiment, the preliminary mask annotation includes bounding boxes and / or masks for objects and / or a class of objects (e.g., people) depicted in the images included in the dataset. In one embodiment, the preliminary mask annotation includes the above-mentioned combination Figure 3 A more detailed description of the initial mask annotations.
[0089] In various embodiments, the system performing method 700 at box B706 trains a model (e.g., a previously untrained neural network) at least in part based on a dataset and preliminary mask annotations. In various embodiments, the trained neural network includes any neural network capable of being trained using segmentation and annotation information. In one example, the trained neural network is a Mask R-CNN without a region proposal network module. Furthermore, at box B704, the neural network is trained using a dataset (including bounding boxes) and preliminary mask annotations at least in part generated by the inference neural network. In various embodiments, the system performing method 700 at box B708 generates a pre-labeling tool as a result of training the neural network. In one embodiment, the pre-labeling tool is a trained neural network that generates fine-grained segmentation (e.g., masks) and annotations for images of a dataset (e.g., a dataset) when inference is performed on an input (e.g., an image). As described in this disclosure, in one embodiment, the pre-labeling tool is used to generate segmentation and annotations for a modified dataset (e.g., a rotated image of the dataset).
[0090] Figure 8This is a flowchart illustrating a method 800 for generating a trained neural network according to some embodiments of the present disclosure. In various embodiments, at block B802, method 800 includes obtaining a training dataset. For example, the training dataset includes a set of images depicting objects with or without additional information (e.g., segmentation information, bounding box information, labeling information, or other information as described above). Furthermore, in various embodiments, at block B804, method 800 includes modifying and / or altering a set of images included in the dataset. In one embodiment, the modification and / or alteration of the set of images augments the dataset by generating at least modified images to reduce the domain gap between the set of images in the dataset and the target domain of the trained neural network, thereby enabling the trained neural network to produce better results during inference. In one example, the images in the training dataset are rotated around an optical axis at different angles (e.g., 5 degrees, -5 degrees, 8 degrees, etc.). In another example, the images are enhanced by at least modifying the scale of the images. In yet another example, in block B804, the brightness values associated with the images are modified.
[0091] In one embodiment, multiple types of modifications or alterations are applied to the set of images to generate modified images. For example, the images are rotated and the scale associated with the images is modified. These modifications and / or alterations can be made individually or in combination. Furthermore, the modifications and / or alterations can be applied to the images sequentially or in parallel.
[0092] As described above, modifications and / or alterations to a set of images may include a variety of different operations, such as rotation, flipping, cropping, modifying exposure, modifying white balance, modifying color, modifying saturation, sharpening images, applying filters, modifying scale, or otherwise modifying, adjusting, or otherwise altering a set of images to represent the environment in which the trained model (e.g., the model obtained as a result of executing method 800) performs inference.
[0093] Back Figure 8 In various embodiments, at box B806, method 800 includes performing inference on the modified dataset by at least providing the modified dataset to a pre-labeling tool. In various embodiments, the pre-labeling tool includes a trained model described in more detail above. For example, pre-labeling tool 208 is a mask R-CNN trained using a dataset (e.g., dataset 102) that includes bounding boxes and annotations. In one embodiment, the pre-labeling tool generates more refined mask annotations for objects depicted in the modified image. For example, as described above... Figure 4In more detail, the pre-labeling tool generates finer mask annotations for specific categories of objects and / or categories within a modified dataset. In various embodiments, the finer mask annotations include additional data and / or metadata identifying pixels (e.g., segmentation information) in the modified images depicting a specific object and / or object category. In one example, the modified images comprise a set of images depicting a person (e.g., a pedestrian) rotated around an optical axis by a set of values. The pre-labeling tool then generates finer mask annotations identifying pixels in the set of images, including people and labels identifying pixels associated with people. As described above, in some examples, the rotation of the images around the optical axis results in inaccurate and / or incorrect bounding boxes and other segmentation information associated with the dataset. In such examples, the pre-labeling tool generates finer mask annotations that provide accurate segmentation information for training neural networks as described in this disclosure.
[0094] In various embodiments, at box B808, method 800 includes training a neural network at least in part based on a modified dataset and more refined mask annotations. In various embodiments, the modified dataset includes a dataset designed to augment the dataset and reduce the domain gaps associated with the environment in which the trained neural network will perform inference as described above. In one embodiment, the neural network includes any neural network capable of being trained using segmentation and / or annotation information (e.g., more refined mask annotations). For example, the neural network is a mask R-CNN trained using a dataset and / or a modified dataset (including modified images and more refined mask annotations generated for the modified dataset). Furthermore, at box B810, method 800 trains the neural network to obtain a trained neural network. In various embodiments, the trained neural network is an environment-robust training model capable of recognizing objects or object categories depicted in an image. For example, as a result of rotating images of a dataset to generate a modified image, the trained neural network is capable of detecting objects in the image regardless of the image's optical angle (e.g., camera angle). In another example, a trained neural network was able to detect objects in low-light images by reducing the brightness values associated with images in the dataset.
[0095] Figure 9 This is a flowchart illustrating a method 900 for modifying a dataset according to some embodiments of the present disclosure. In various embodiments, at block B902, method 900 includes obtaining an image and tags of objects depicted in the image. For example, the image is obtained from a dataset, as described above. Figure 1The dataset 102 is described. In various embodiments, labels are included in the dataset. In other embodiments, the labels are obtained from a neural network or other model. In various embodiments, at box B904, method 900 includes obtaining a segmentation of an image to distinguish the pixels of an object from other pixels in the image. For example, segmentation is performed using data trained on a selected dataset (e.g., as described above). Figure 1 The described pre-labeling tool 108) uses a masked R-CNN to obtain image segmentation. In other embodiments, segmentation is obtained manually or semi-manually. For example, a neural network or other model generates segmentation information for the image, and the user verifies and / or adjusts the output.
[0096] In various embodiments, at block B906, method 900 includes performing a set of transformations on an image to obtain a set of transformed images. For example, as described above, the image is rotated about an axis by different values to generate a set of rotated images. Other examples of transformations include stretching, translating, scaling, color correction, cropping, trimming, otherwise modifying the image, or combinations of transformations performed in parallel or serially.
[0097] In various embodiments, at block B908, method 900 includes using the obtained segmentation to determine a set of bounding boxes of an object depicted in a set of transformed images. For example, a transformation applied to the images to obtain a set of transformed images is applied to the segmentation to determine the location of the object in the transformed images. In various embodiments, calculating the bounding boxes includes calculating boxes with angles having the following angles: (Xmin, Ymax), (Xmin, Ymin), (Xmax, Ymax), (Xmax, Ymin), where Xmin is the x-coordinate of the leftmost pixel of the segmentation, Xmax is the x-coordinate of the rightmost pixel of the segmentation, Ymin is the y-coordinate of the bottommost pixel of the segmentation, and Ymax is the y-coordinate of the topmost pixel of the segmentation. In still other embodiments, the bounding box consists of two sets of coordinates (e.g., (Xmin, Ymax) and (Xmax, Ymin)) and at least one length value (e.g., the length of one side of a square or the length of the bottom and height of a rectangle). Other methods for determining the bounding boxes of objects can be used in conjunction with this disclosure. For example, in embodiments where the object includes long-tailed or similar components that make it difficult to generate a bounding box that only includes the depicted object, histograms or other statistical techniques are used to select a minimum perimeter box that surrounds pixels by a threshold (e.g., 95%) or other value to prevent the bounding box from including at least a portion of the image that does not depict the object's pixels.
[0098] In various embodiments, at box B910, method 900 includes associating tags with bounding boxes of objects in a set of transformed images. For example, a set of transformed images is added to a dataset that includes tags and bounding box information generated as described above. In various embodiments, a set of transformed images is stored in a dataset according to the dataset's format. Furthermore, in various embodiments, the dataset including the set of transformed images is used to train a transformation-robust neural network. For example, because the images are rotated during the transformation, a neural network trained using a dataset including the transformed images and bounding box information is rotation-robust when performing inference. Figure 9 As shown, in various embodiments, method 900 is repeated to augment the dataset. For example, as described above, transformations are applied sequentially to further reduce the domain gaps. In various embodiments, method 900 is performed to generate a set of rotated image and bounding box information for augmenting the dataset, and then repeated to generate a set of stretched image and bounding box information for augmenting the dataset.

In at least one embodiment, the AEB system may use one or more forward-facing cameras and / or one or more RADAR sensors 1360 coupled to a dedicated processor, DSP, FPGA, and / or ASIC. In at least one embodiment, when the AEB system detects a hazard, it typically first warns the driver to take corrective action to avoid a collision, and if the driver does not take corrective action, the AEB system may automatically apply brakes to attempt to prevent or at least mitigate the effects of the predicted collision. In at least one embodiment, the AEB system may include techniques such as dynamic braking to support and / or brakes for impending collisions.
[0217] In at least one embodiment, when vehicle 1300 crosses lane markings, the LDW system provides visual, auditory, and / or tactile warnings, such as steering wheel or seat vibrations, to alert the driver. In at least one embodiment, the LDW system is inactive when the driver indicates intentional lane departure, such as by activating turn signals. In at least one embodiment, the LDW system may use a front-facing camera coupled to a dedicated processor, DSP, FPGA, and / or ASIC, which is electrically coupled to provide driver feedback such as a display, speaker, and / or vibration components.

[0219] In at least one embodiment, the RCTW system can provide visual, auditory, and / or tactile notifications when an object is detected outside the range of the rear camera while the vehicle 1300 is reversing. In at least one embodiment, the RCTW system includes an AEB system to ensure the applied vehicle brakes to avoid a collision. In at least one embodiment, the RCTW system may use one or more rear-facing RADAR sensors 1360 coupled to a dedicated processor, DSP, FPGA, and / or ASIC, which are electrically coupled to provide driver feedback such as displays, speakers, and / or vibration components.
[0220] In at least one embodiment, conventional ADAS systems may be prone to generating false alarms, which can be annoying and distracting to the driver, but are generally not catastrophic because conventional ADAS systems warn the driver and allow the driver to determine whether a safe situation truly exists and take appropriate action. In at least one embodiment, in the event of conflicting results, the vehicle 1300 itself decides whether to follow the result of the main computer or the auxiliary computer (e.g., the first or second controller of controller 1336). For example, in at least one embodiment, ADAS system 1338 may be a backup and / or auxiliary computer for providing perception information to a backup computer rationality module. In at least one embodiment, the backup computer rationality monitor may run redundant software on hardware components to detect faults in perception and dynamic driving tasks. In at least one embodiment, the output from ADAS system 1338 may be provided to a monitoring MCU. In at least one embodiment, if the output from the main computer and the output from the auxiliary computer conflict, the monitoring MCU decides how to reconcile the conflict to ensure safe operation.
[0221] In at least one embodiment, the master computer may be configured to provide a confidence score to the supervisory MCU to indicate the master computer's confidence in the selected result. In at least one embodiment, if the confidence score exceeds a threshold, the supervisory MCU may follow the master computer's instructions regardless of whether the auxiliary computer provides conflicting or inconsistent results. In at least one embodiment, if the confidence score does not meet the threshold, and if the master computer and the auxiliary computer indicate different results (e.g., conflicting), the supervisory MCU may arbitrate between the computers to determine the appropriate result.
[0222] In at least one embodiment, the supervisory MCU may be configured to run a neural network trained and configured to determine, at least in part, the conditions under which the auxiliary computer provides a false alarm based on outputs from a host computer and an auxiliary computer. In at least one embodiment, the neural network in the supervisory MCU may learn when the outputs of the auxiliary computer can be trusted and when they cannot. For example, in at least one embodiment, when the auxiliary computer is a RADAR-based FCW system, the neural network in the supervisory MCU may learn when the FCW system recognizes a metallic object that is not actually dangerous, such as a drain grating or manhole cover that would trigger an alarm. In at least one embodiment, when the auxiliary computer is a camera-based LDW system, the neural network in the supervisory MCU may learn to override the LDW when a cyclist or pedestrian is present and lane departure is actually the safest operation. In at least one embodiment, the supervisory MCU may include at least one of a DLA or GPU suitable for running a neural network with associated memory. In at least one embodiment, the supervisory MCU may include and / or be included as a component of one or more SoC 1304s.
[0223] In at least one embodiment, the ADAS system 1338 may include an auxiliary computer that performs ADAS functions using conventional computer vision rules. In at least one embodiment, the auxiliary computer may use classic computer vision rules (if-then), and the presence of a neural network in the supervisory MCU can improve reliability, security, and performance. For example, in at least one embodiment, diverse implementations and intentional non-identity make the entire system more fault-tolerant, especially for failures caused by software (or software-hardware interface) functionality. For example, in at least one embodiment, if a software vulnerability or bug exists in the software running on the host computer, and different software code running on the auxiliary computer provides consistent overall results, the supervisory MCU can more confidently assume that the overall result is correct and that the vulnerability in the software or hardware on the host computer will not lead to a significant error.
[0224] In at least one embodiment, the output of the ADAS system 1338 can be input to the perception module and / or the dynamic driving task module of the host computer. For example, in at least one embodiment, if the ADAS system 1338 indicates a forward collision warning due to an object directly ahead, the perception block can use this information when identifying the object. In at least one embodiment, as described herein, the assistance computer can have its own neural network trained to reduce the risk of false alarms.
[0225] In at least one embodiment, vehicle 1300 may further include an infotainment SoC 1330 (e.g., an in-vehicle infotainment system (IVI)).

In at least one embodiment, the infotainment SoC 1330 may further be used to provide information (e.g., visual and / or auditory) to a user of vehicle 1300, such as information from ADAS system 1338, autonomous driving information (such as planned vehicle maneuvers), trajectory, surrounding environment information (e.g., intersection information, vehicle information, road information, etc.) and / or other information.
[0226] In at least one embodiment, the infotainment SoC 1330 may include any number and type of GPU functionality. In at least one embodiment, the infotainment SoC 1330 may communicate with other devices, systems, and / or components of the vehicle 1300 via bus 1302.

[0259] Figure 18A An exemplary architecture is illustrated in which multiple GPUs 1810(1)-1810(N) are communicatively coupled to multiple multi-core processors 1805(1)-1805(M) via high-speed links 1840(1)-1840(N) (e.g., bus / point-to-point interconnect, etc.). In at least one embodiment, the high-speed links 1840(1)-1840(N) support communication throughput of 4GB / s, 30GB / s, 80GB / s, or higher. In at least one embodiment, various interconnect protocols may be used, including but not limited to PCIe 4.0 or 5.0 and NVLink 2.0. In the various figures, “N” and “M” represent positive integers, the values of which may vary from figure to figure.
[0260] Furthermore, in at least one embodiment, two or more GPUs 1810 are interconnected via high-speed links 1829(1)-1829(2), which can be implemented using a protocol / link similar to or different from that used for high-speed links 1840(1)-1840(N). Similarly, two or more multi-core processors 1805 can be connected via high-speed link 1828, which can be a symmetric multiprocessor (SMP) bus operating at speeds of 20GB / s, 30GB / s, 120GB / s, or higher. Alternatively, similar protocols / links (e.g., via a common interconnect structure) can be used. Figure 18A This shows all communication between the various system components.
[0261] In at least one embodiment, each multi-core processor 1805 is communicatively coupled to processor memories 1801(1)-1801(M) via memory interconnects 1826(1)-1826(M), and each GPU 1810(1)-1810(N) is communicatively coupled to GPU memories 1820(1)-1820(N) via GPU memory interconnects 1850(1)-1850(N). In at least one embodiment, memory interconnects 1826 and 1850 may utilize similar or different memory access technologies. By way of example and not limitation, processor memories 1801(1)-1801(M) and GPU memories 1820 may be volatile memories, such as dynamic random access memory (DRAM) (including stacked DRAM), graphics DDR SDRAM (GDDR) (e.g., GDDR5, GDDR6), or high bandwidth memory (HBM), and / or may be non-volatile memories, such as 3D XPoint or Nano-RAM. In at least one embodiment, some portions of the processor memory 1801 may be volatile memory, while other portions may be non-volatile memory (e.g., using a two-level memory (2LM) hierarchy).
[0262] As described herein, although various multi-core processors 1805 and GPUs 1810 can be physically coupled to specific memories 1801 and 1820 respectively, and / or can implement a unified memory architecture, in which the virtual system address space (also known as the “effective address” space) is distributed among the various physical memories. For example, processor memories 1801(1)-1801(M) can each contain 64GB of system memory address space, and GPU memories 1820(1)-1820(N) can each contain 32GB of system memory address space, resulting in a total addressable memory size of 256GB when M=2 and N=4. N and M may also be other values.
[0263] Figure 18B Additional details are shown regarding the interconnection between a multi-core processor 1807 and a graphics acceleration module 1846 according to an exemplary embodiment. In at least one embodiment, the graphics acceleration module 1846 may include one or more GPU chips integrated on a line card coupled to the processor 1807 via a high-speed link 1840 (e.g., PCIe bus, NVLink, etc.). In at least one embodiment, the graphics acceleration module 1846 may optionally be integrated on a package or chip having the processor 1807.
[0264] In at least one embodiment, the processor 1807 includes a plurality of cores 1860A-1860D, each core having a translation back cover buffer (“TLB”) 1861A-1861D and one or more caches 1862A-1862D. In at least one embodiment, the cores 1860A-1860D may include various other components (not shown) for executing instructions and processing data. In at least one embodiment, the caches 1862A-1862D may include level 1 (L1) and level 2 (L2) caches. Furthermore, one or more shared caches 1856 may be included in the caches 1862A-1862D and shared by the respective groups of cores 1860A-1860D. For example, one embodiment of the processor 1807 includes 24 cores, each core having its own L1 cache, twelve shared L2 caches, and twelve shared L3 caches. In this embodiment, two adjacent cores share one or more L2 and L3 caches. In at least one embodiment, the processor 1807 and the graphics acceleration module 1846 are connected to a system memory 1814, which may include... Figure 18A The processor memory in the memory is 1801(1)-1801(M).
[0265] In at least one embodiment, consistency of data and instructions stored in the various caches 1862A-1862D, 1856 and system memory 1814 is maintained via inter-core communication through the consistency bus 1864. In at least one embodiment, for example, each cache may have associated cache consistency logic / circuit to communicate via the consistency bus 1864 in response to the detection of a read or write to a particular cache line. In at least one embodiment, a cache snooping protocol is implemented via the consistency bus 1864 to snoop on cache accesses.
[0266] In at least one embodiment, proxy circuitry 1825 communicatively couples graphics acceleration module 1846 to coherence bus 1864, thereby allowing graphics acceleration module 1846 to participate in cache coherence protocols as a peer of cores 1860A-1860D. Specifically, in at least one embodiment, interface 1835 provides connectivity to proxy circuitry 1825 via high-speed link 1840, and interface 1837 connects graphics acceleration module 1846 to high-speed link 1840.
[0267] In at least one embodiment, the accelerator integrated circuit 1836 provides cache management, memory access, context management, and interrupt management services for a plurality of graphics processing engines 1831(1)-1831(N) of the graphics acceleration module. In at least one embodiment, the graphics processing engines 1831(1)-1831(N) may each include a separate graphics processing unit (GPU). In at least one embodiment, the graphics processing engines 1831(1)-1831(N) may optionally include different types of graphics processing engines within the GPU, such as graphics execution units, media processing engines (e.g., video encoders / decoders), samplers, and blit engines. In at least one embodiment, the graphics acceleration module 1846 may be a GPU having a plurality of graphics processing engines 1831(1)-1831(N), or the graphics processing engines 1831(1)-1831(N) may be individual GPUs integrated on a general-purpose package, line card, or chip.
[0268] In at least one embodiment, the accelerator integrated circuit 1836 includes a memory management unit (MMU) 1839 for performing various memory management functions, such as virtual-to-physical memory translation (also known as effective-to-real memory translation), and a memory access protocol for accessing system memory 1814. In at least one embodiment, the MMU 1839 may also include a translation back buffer (“TLB”) (not shown) for caching virtual / effective-to-physical / real address translations. In at least one embodiment, a cache 1838 may store commands and data for efficient access by the graphics processing engines 1831(1)-1831(N). In at least one embodiment, a fetch unit 1844 may be used to keep data stored in the cache 1838 and graphics memories 1833(1)-1833(M) consistent with the core caches 1862A-1862D, 1856 and system memory 1814. As previously mentioned, this task can be accomplished via proxy circuitry 1825 representing cache 1838 and graphics memory 1833(1)-1833(M) (e.g., sending updates related to the modification / access of cache lines on processor caches 1862A-1862D, 1856 to cache 1838 and receiving updates from cache 1838).
[0269] In at least one embodiment, a set of registers 1845 stores context data of threads executed by graphics processing engines 1831(1)-1831(N), and context management circuitry 1848 manages the thread context. For example, context management circuitry 1848 can perform save and restore operations to save and restore the context of individual threads during context switching (e.g., saving the first thread and storing the second thread so that the second thread can be executed by the graphics processing engine). For example, during context switching, context management circuitry 1848 can store the current register value in a designated area of memory (e.g., identified by a context pointer). The register value can then be restored when returning to the context. In at least one embodiment, interrupt management circuitry 1847 receives and processes interrupts received from system devices.
[0270] In at least one embodiment, MMU 1839 translates virtual / effective addresses from graphics processing engine 1831 into real / physical addresses in system memory 1814. In at least one embodiment, accelerator integrated circuit 1836 supports multiple (e.g., 4, 8, 16) graphics accelerator modules 1846 and / or other accelerator devices. In at least one embodiment, graphics accelerator module 1846 may be dedicated to a single application executing on processor 1807, or may be shared among multiple applications. In at least one embodiment, a virtualized graphics execution environment is presented, wherein resources of graphics processing engines 1831(1)-1831(N) are shared with multiple applications or virtual machines (VMs). In at least one embodiment, resources may be subdivided into “slices” based on processing requirements and priorities associated with VMs and / or applications, which are allocated to different VMs and / or applications.
[0271] In at least one embodiment, the accelerator integrated circuit 1836 acts as a bridge to the system of the graphics acceleration module 1846 and provides address translation and system memory caching services. Additionally, in at least one embodiment, the accelerator integrated circuit 1836 can provide virtualization facilities for the host processor to manage the virtualization, interrupt, and memory management of the graphics processing engines 1831(1)-1831(N).
[0272] In at least one embodiment, since the hardware resources of the graphics processing engines 1831(1)-1831(N) are explicitly mapped to the real address space seen by the host processor 1807, any host processor can directly address these resources using valid address values. In at least one embodiment, a function of the accelerator integrated circuit 1836 is to physically separate the graphics processing engines 1831(1)-1831(N) so that they appear as independent units to the system.
[0273] In at least one embodiment, one or more graphics memories 1833(1)-1833(M) are coupled to each graphics processing engine 1831(1)-1831(N), and N = M. In at least one embodiment, the graphics memories 1833(1)-1833(M) store instructions and data processed by each graphics processing engine 1831(1)-1831(N). In at least one embodiment, the graphics memories 1833(1)-1833(M) may be volatile memory, such as DRAM (including stacked DRAM), GDDR memory (e.g., GDDR5, GDDR6), or HBM, and / or may be non-volatile memory, such as 3DXPoint or Nano-RAM.
[0274] In at least one embodiment, to reduce data traffic on the high-speed link 1840, a biasing technique is used to ensure that the data stored in the graphics memory 1833(1)-1833(M) is the data most frequently used by the graphics processing engine 1831(1)-1831(N), and preferably data that the cores 1860A-1860D do not use (or at least do not use frequently). Similarly, in at least one embodiment, the biasing mechanism attempts to keep the data needed by the cores (and preferably not the graphics processing engine 1831(-1)-1831(N)) in the caches 1862A-1862D, 1856 and system memory 1814.
[0275] Figure 18C Another exemplary embodiment is shown, in which the accelerator integrated circuit 1836 is integrated within the processor 1807. In this embodiment, the graphics processing engines 1831(1)-1831(N) communicate directly with the accelerator integrated circuit 1836 via a high-speed link 1840 through interfaces 1837 and 1835 (which may also be any form of bus or interface protocol). In at least one embodiment, the accelerator integrated circuit 1836 can perform operations related to... Figure 18B The described operation is similar to that of the accelerator integrated circuit. However, due to its close proximity to the coherence bus 1864 and caches 1862A-1862D, 1856, it may have higher throughput. In at least one embodiment, the accelerator integrated circuit supports different programming models, including a dedicated process programming model (without graphics acceleration module virtualization) and a shared programming model (with virtualization), which may include a programming model controlled by the accelerator integrated circuit 1836 and a programming model controlled by the graphics acceleration module 1846.
[0276] In at least one embodiment, graphics processing engines 1831(1)-1831(N) are dedicated to a single application or process under a single operating system. In at least one embodiment, a single application can funnel requests from other applications to graphics processing engines 1831(1)-1831(N), thereby providing virtualization within a VM / partition.
[0277] In at least one embodiment, graphics processing engines 1831(1)-1831(N) can be shared by multiple VM / application partitions. In at least one embodiment, the shared model can use a hypervisor to virtualize graphics processing engines 1831(1)-1831(N) to allow each operating system to access them. In at least one embodiment, for a single-partition system without a hypervisor, the operating system owns graphics processing engines 1831(1)-1831(N). In at least one embodiment, the operating system can virtualize graphics processing engines 1831(1)-1831(N) to provide access to each process or application.
[0278] In at least one embodiment, the graphics acceleration module 1846 or the individual graphics processing engine 1831(1)-1831(N) uses a process handle to select a process element. In at least one embodiment, the process element is stored in system memory 1814 and can be addressed using the effective address to real address translation techniques described herein. In at least one embodiment, the process handle may be an implementation-specific value provided to the host process when registering its context with the graphics processing engine 1831(1)-1831(N) (i.e., invoking system software to add the process element to the process element linked list). In at least one embodiment, the lower 16 bits of the process handle may be the offset of the process element in the process element linked list.
[0279] Figure 18DAn exemplary accelerator integration slice 1890 is illustrated. In at least one embodiment, a "slice" includes a designated portion of the processing resources of an accelerator integrated circuit 1836. In at least one embodiment, the application is an effective address space 1882 in system memory 1814, which stores process element 1883. In at least one embodiment, process element 1883 is stored in response to a GPU call 1881 from an application 1880 executing on processor 1807. In at least one embodiment, process element 1883 contains the process state of the corresponding application 1880. In one embodiment, a job descriptor (WD) 1884 contained in process element 1883 may be a single job requested by the application, or it may contain a pointer to a job queue. In at least one embodiment, WD 1884 is a pointer to a job request queue in the effective address space 1882 of the application.
[0280] In at least one embodiment, the graphics acceleration module 1846 and / or the various graphics processing engines 1831(1)-1831(N) may be shared by all processes or a subset of processes in the system. In at least one embodiment, infrastructure may be included for setting process states and sending WD 1884 to the graphics acceleration module 1846 to begin operations in a virtualized environment.
[0281] In at least one embodiment, the dedicated process programming model is implementation-specific. In at least one embodiment, in this model, a single process owns either the graphics acceleration module 1846 or an individual graphics processing engine 1831. In at least one embodiment, when the graphics acceleration module 1846 is owned by a single process, the hypervisor initializes the accelerator integrated circuit for the owned partition, and when the graphics acceleration module 1846 is assigned, the operating system initializes the accelerator integrated circuit 1836 for the owned process.
[0282] In at least one embodiment, during operation, the WD acquisition unit 1891 in the accelerator integration slice 1890 acquires the next WD 1884, which includes instructions for work to be performed by one or more graphics processing engines of the graphics acceleration module 1846. In at least one embodiment, data from the WD 1884 may be stored in register 1845 and used by the MMU 1839, interrupt management circuitry 1847, and / or context management circuitry 1848, as shown. For example, one embodiment of the MMU 1839 includes segment / page roaming circuitry for accessing segment / page tables 1886 within the OS virtual address space 1885. In at least one embodiment, the interrupt management circuitry 1847 may process an interrupt event 1892 received from the graphics acceleration module 1846. In at least one embodiment, when performing graphics operations, a valid address 1893 generated by the graphics processing engines 1831(1)-1831(N) is translated into a real address by the MMU 1839.
[0283] In at least one embodiment, register 1845 is copied for each graphics processing engine 1831(1)-1831(N) and / or graphics acceleration module 1846, and said register 1845 may be initialized by a hypervisor or operating system. In at least one embodiment, each of these copied registers may be included in accelerator integration slice 1890. Exemplary registers that may be initialized by a hypervisor are shown in Table 1.
[0284]
[0285] Table 2 shows exemplary registers that can be initialized by the operating system.

[0287] In at least one embodiment, each WD 1884 is specific to a particular graphics acceleration module 1846 and / or graphics processing engine 1831(1)-1831(N). In at least one embodiment, it contains all the information required for the graphics processing engine 1831(1)-1831(N) to complete its work, or it may be a pointer to a memory location where the application has set up a command queue for the work to be completed.
[0288] Figure 18E Additional details of an exemplary embodiment of the shared model are shown. This embodiment includes a hypervisor real address space 1898, in which a list of process elements 1899 is stored. In at least one embodiment, the hypervisor real address space 1898 can be accessed via a hypervisor 1896, which virtualizes the graphics acceleration module engine for operating system 1895.
[0289] In at least one embodiment, the shared programming model allows all processes or subsets of processes from all partitions or subsets of partitions in the system to use the graphics acceleration module 1846. In at least one embodiment, there are two programming models in which the graphics acceleration module 1846 is shared by multiple processes and partitions, namely, time-slice sharing and graphics-oriented sharing.
[0290] In at least one embodiment, in this model, the hypervisor 1896 owns the graphics acceleration module 1846 and makes its functionality available to all operating systems 1895. In at least one embodiment, for the graphics acceleration module 1846 to support virtualization through the hypervisor 1896, the graphics acceleration module 1846 may comply with certain requirements, such as (1) the job requests of the application must be autonomous (i.e., no state needs to be maintained between jobs), or the graphics acceleration module 1846 must provide a context saving and recovery mechanism, (2) the graphics acceleration module 1846 guarantees that the job requests of the application are completed within a specified amount of time, including any conversion errors, or the graphics acceleration module 1846 provides the ability to preempt job processing, and (3) when operating in a directed shared programming model, fairness between the processes of the graphics acceleration module 1846 must be ensured.
[0291] In at least one embodiment, application 1880 needs to make operating system 1895 system calls using the graphics acceleration module type, working descriptor (WD), permission mask register (AMR) value, and context save / restore region pointer (CSRP). In at least one embodiment, the graphics acceleration module type describes the target acceleration function for the system call. In at least one embodiment, the graphics acceleration module type can be a system-specific value. In at least one embodiment, the WD is specifically formatted for graphics acceleration module 1846 and can take the form of graphics acceleration module 1846 commands, valid address pointers to user-defined structures, valid address pointers to command queues, or any other data structure describing the work to be performed by graphics acceleration module 1846.
[0292] In at least one embodiment, the AMR value is the AMR state for the current process. In at least one embodiment, the value passed to the operating system is similar to that of the application that sets the AMR. In at least one embodiment, if the implementation of the accelerator integrated circuit 1836 (not shown) and the graphics acceleration module 1846 does not support the User Rights Mask Overwrite Register (UAMOR), the operating system may apply the current UAMOR value to the AMR value before passing the AMR in the hypervisor call. In at least one embodiment, the hypervisor 1896 may selectively apply the current Rights Mask Overwrite Register (AMOR) value before placing the AMR into the process element 1883. In at least one embodiment, CSRP is one of the registers 1845 containing the effective address of a region in the effective address space 1882 of the application for the graphics acceleration module 1846 to save and restore the context state. In at least one embodiment, this pointer is optional if it is not necessary to save state between jobs or when a job is preempted. In at least one embodiment, the context save / restore region may be fixed system memory.
[0293] Upon receiving a system call, operating system 1895 can verify that application 1880 has been registered and granted permission to use graphics acceleration module 1846. Then, in at least one embodiment, operating system 1895 uses the information shown in Table 3 to invoke hypervisor 1896.
[0294]
[0295]
[0296] In at least one embodiment, upon receiving a hypervisor call, hypervisor 1896 verifies that operating system 1895 has been registered and granted permission to use graphics acceleration module 1846. Then, in at least one embodiment, hypervisor 1896 adds process element 1883 to a linked list of process elements of the corresponding graphics acceleration module 1846 type. In at least one embodiment, the process element may include the information shown in Table 4.
[0297]
[0298] In at least one embodiment, the hypervisor initializes multiple accelerator integration slice 1890 registers 1845.
[0299] like Figure 18FAs shown, in at least one embodiment, a unified memory is used, which is addressable via a common virtual memory address space for accessing physical processor memories 1801(1)-1801(N) and GPU memories 1820(1)-1820(N). In this implementation, operations performed on GPUs 1810(1)-1810(N) utilize the same virtual / effective memory address space to access processor memories 1801(1)-1801(M) and vice versa, thereby simplifying programmability. In at least one embodiment, a first portion of the virtual / effective address space is allocated to processor memory 1801(1), a second portion to second processor memory 1801(N), a third portion to GPU memory 1820(1), and so on. In at least one embodiment, the entire virtual / effective memory space (sometimes referred to as the effective address space) is thus distributed across each of processor memory 1801 and GPU memory 1820, thereby allowing any processor or GPU to access that memory using a virtual address mapped to any physical memory.
[0300] In at least one embodiment, the bias / coherence management circuitry 1894A-1894E within one or more MMUs 1839A-1839E ensures cache coherence between one or more host processors (e.g., 1805) and the cache of the GPU 1810, and implements biasing techniques to indicate the physical memory in which certain types of data should be stored. In at least one embodiment, although in Figure 18F Several instances of bias / coherence management circuits 1894A-1894E are shown, but bias / coherence circuits can be implemented within the MMU of one or more host processors 1805 and / or within the accelerator integrated circuit 1836.
[0301] One embodiment allows GPU memory 1820 to be mapped as part of system memory and accessed using shared virtual memory (SVM) technology without suffering the performance drawbacks associated with full system cache coherence. In at least one embodiment, the ability to access GPU memory 1820 as system memory without the heavy overhead of cache coherence provides a favorable operating environment for GPU offloading. In at least one embodiment, this arrangement allows the host processor 1805 to software-set operands and access computation results without the overhead of conventional I / O DMA data copying. In at least one embodiment, such conventional copying includes driver calls, interrupts, and memory-mapped I / O (MMIO) accesses, all of which are less efficient than simple memory accesses. In at least one embodiment, the ability to access GPU memory 1820 without cache coherence overhead may be critical to the execution time of offloaded computations. In at least one embodiment, for example, in cases with high streaming write memory traffic, cache coherence overhead can significantly reduce the effective write bandwidth seen by GPU 1810. In at least one embodiment, the efficiency of operand setting, the efficiency of result access, and the efficiency of GPU computation may play a role in determining the effectiveness of GPU offloading.
[0302] In at least one embodiment, the selection of GPU bias and host processor bias is driven by a bias tracker data structure. In at least one embodiment, for example, a bias table can be used, which may be a page-granular structure (e.g., controlled at the memory page level) comprising one or two bits of memory pages attached to each GPU. In at least one embodiment, with or without a bias cache (e.g., for caching frequently / recently used entries in the bias table) in GPU 1810, the bias table can be implemented across one or more stolen memory ranges of GPU memory 1820. Alternatively, in at least one embodiment, the entire bias table can be maintained within the GPU.
[0303] In at least one embodiment, prior to actual access to GPU memory, an access to the bias table entry associated with each access to GPU-attached memory 1820 is performed, resulting in the following operations: In at least one embodiment, a local request from GPU 1810 to find its page in the GPU bias is forwarded directly to the corresponding GPU memory 1820. In at least one embodiment, a local request from the GPU to find its page in the host bias is forwarded to processor 1805 (e.g., via the high-speed link described herein). In at least one embodiment, a request from processor 1805 to find the requested page in the host processor bias completes a request similar to a normal memory read. Alternatively, a request for a page pointing to the GPU bias can be forwarded to GPU 1810. In at least one embodiment, if the GPU is not currently using the page, the GPU may subsequently migrate the page to the host processor bias. In at least one embodiment, the page bias state can be changed through a software-based mechanism, a hardware-assisted software mechanism, or, in limited cases, a purely hardware-based mechanism.
[0304] In at least one embodiment, a mechanism for changing the bias state employs an API call (e.g., OpenCL), which subsequently invokes the GPU's device driver. The device driver then sends a message (or enqueues a command descriptor) to the GPU, instructing the GPU to change the bias state and, in some migration, performs a cache refresh operation on the host. In at least one embodiment, the cache refresh operation is used for migration from the host processor 1805 bias to the GPU bias, but not for the reverse migration.
[0305] In at least one embodiment, cache coherence is maintained by temporarily rendering GPU bias pages that the host processor 1805 cannot cache. In at least one embodiment, to access these pages, the processor 1805 may request access from the GPU 1810, which may or may not immediately grant access. Therefore, in at least one embodiment, to reduce communication between the processor 1805 and the GPU 1810, it is beneficial to ensure that the GPU bias pages are pages needed by the GPU, not those needed by the host processor 1805, and vice versa.
