Description

Technical Field

[0001] At least one embodiment relates to a processing resource that uses one or more neural networks to generate synthetic data for use as training data for one or more different neural networks to perform a task. For example, a processor comprising one or more circuits uses one or more first neural networks to train one or more second neural networks to perform according to one or more performance metrics. Background Art

[0002] Without sufficient training data, training a neural network can be ineffective. For example, to perform facial recognition, sufficient training images are essential to improve the accuracy of the trained neural network. A lack of available training images can lead to suboptimal performance when performing facial recognition. Collecting a sufficient dataset covering different types of training images is often prohibitively expensive, time-consuming, and sometimes impractical. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] In at least one embodiment, systems and methods implemented in accordance with the present disclosure are used to cause one or more first neural networks to train one or more second neural networks to perform according to one or more performance metrics and / or otherwise perform the operations discussed herein.

[0058] In at least one embodiment, a neural network can be used to perform facial recognition tasks and / or otherwise perform the operations discussed herein. When a neural network is trained, any deficiencies in a training dataset (e.g., facial images) due to underrepresentation of certain facial features or attributes (such as race, gender, age, emotion, etc.) can result in poor performance of the neural network in performing facial recognition tasks. Some of the main challenges of facial recognition in unconstrained environments are due to variations associated with occlusion, head pose, lighting, and facial expression.

[0059] In at least one embodiment, facial recognition algorithms are developed using large datasets to train deep neural networks (DNNs). Even if such systems are highly accurate after training with large-scale datasets, these networks can inherit data biases from them. For example, if a certain age group is underrepresented in the dataset, the developed system may perform poorly for that category. Without proper testing across a wide range of attributes, inaccuracies can arise in the trained system. After organizing a well-represented test dataset that measures performance across all attributes, the system can identify categories for which the system performs poorly.

[0060] Synthetic data generation can be a solution to address the limitations of real-world datasets, which are expensive, time-consuming, and sometimes impractical to obtain. In at least one embodiment, after identifying facial features or attributes for which a lack of training images causes a neural network to perform poorly, another neural network can use this information to generate synthetic facial images corresponding to the identified facial features or attributes for which the neural network performs poorly.

[0061] In at least one embodiment, the first neural network can be a generative adversarial network (GAN). In at least one embodiment, the GAN synthetically generates and synthesizes highly realistic and high-quality facial images with desired facial features or attributes. In at least one embodiment, the synthetic images generated by the GAN are then used by one or more second neural networks for facial recognition tasks and / or otherwise perform the operations discussed herein. In at least one embodiment, other techniques and artificial intelligence (AI)-based generators (such as transformers, diffusion models, image diffusion models, stable diffusion AI, and DALL-E 2, etc.) can be used to synthetically generate one or more images.

[0062] In at least one embodiment, as an enrollment step, reference images associated with an identity are provided to the system. In at least one embodiment, during inference time, the system obtains reference images during the user enrollment step. In at least one embodiment, these images are stored in a database for comparison with test images to make recognition decisions. In at least one embodiment, in order for the system to be robust to attributes such as head pose, facial expression, makeup, lighting differences, etc., multiple reference images need to be obtained during the enrollment step. In at least one embodiment, the first neural network circumvents this requirement by synthesizing variations of one or more images provided by the user for enrollment. In at least one embodiment, the first neural network generates variations of the reference images in a sequential manner by controlling the attributes of interest with different facial poses, lighting, angles, etc., where the face identity is preserved to a certain extent and then stores the reference images and the synthesized images in a database.

[0063] The techniques presented herein enable facial recognition tasks to be robust not only to training data but also during inference or test time. In at least one embodiment, to ensure that generated variations of a reference image do not change its identity, the first neural network performs a filtering task to discard generated variations of the reference image that change the identity of the reference image. In at least one embodiment, to perform filtering, data clustering techniques are utilized to detect outliers using a collection of facial recognition models of variations of the reference image. In at least one embodiment, each generated variation of the reference image is compared to the reference image. In at least one embodiment, an identity value is calculated for each generated variation of the reference image. In at least one embodiment, the filtering task discards generated variations of the reference image that have an associated identity value greater than a defined threshold, and the remaining variations are stored in a database for use in training the second neural network.

[0064] In the preceding and following descriptions, various techniques are described. For purposes of explanation, specific configurations and details are set forth to provide a thorough understanding of possible ways to implement the techniques. However, it will also be apparent that the techniques described below can be practiced in different configurations without the specific details. Furthermore, well-known features may be omitted or simplified to avoid obscuring the described techniques.

In at least one embodiment, process 200 includes one or more steps of determining 202 whether poor performance results of a facial recognition unit analyzed by a performance analysis unit and transmitted to one or more first neural networks are a result of insufficient training data (e.g., facial images) for one or more second neural networks, if the determination 202 is negative, identifying 204 a root cause of the poor performance, if the determination 202 is positive, determining 206 whether the insufficiency of the training images is with respect to specific facial features and / or attributes, if 206 is negative, identifying 208 a reason for the insufficiency of the training images, and if 206 is positive, generating 210 a synthetic image associated with the specific facial features and / or attributes.

[0244] In at least one embodiment, conventional ADAS systems can be prone to generating false positive results, which can be annoying and distracting to the driver, but are generally not catastrophic, as conventional ADAS systems alert the driver and allow the driver to decide whether a safe condition truly exists and take action accordingly. In at least one embodiment, in the event of conflicting results, the vehicle 1000 independently decides whether to follow the results of the primary computer or the secondary computer (e.g., the first or second controller in controller 1036). For example, in at least one embodiment, the ADAS system 1038 can be a backup and / or secondary computer that provides perception information to a backup computer rationality module. In at least one embodiment, the backup computer rationality monitor can run redundant software on hardware components to detect failures in perception and dynamic driving tasks.

[0245] In at least one embodiment, the primary computer can be configured to provide a confidence score to the supervisory MCU that indicates the primary computer's confidence in the selected result. In at least one embodiment, if the confidence score exceeds a threshold, the supervisory MCU can follow the primary computer's instructions regardless of whether the secondary computer provides conflicting or inconsistent results. In at least one embodiment, if the confidence score does not meet the threshold, and if the primary and secondary computers indicate different results (e.g., a conflict), the supervisory MCU can arbitrate between the computers to determine the appropriate result.

[0246] In at least one embodiment, the supervisory MCU can be configured to run a neural network that is trained and configured to determine conditions under which the auxiliary computer provides a false alarm based, at least in part, on output from the primary computer and output from the auxiliary computer. In at least one embodiment, the one or more neural networks in the supervisory MCU can learn when the output of the auxiliary computer can be trusted and when it cannot be trusted. For example, in at least one embodiment, when the auxiliary computer is a RADAR-based FCW system, the one or more neural networks in the supervisory MCU can learn when the FCW system is identifying a metal object that is not actually a danger, such as a drain grate 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 can learn to override LDW when a cyclist or pedestrian is present and lane departure is actually the safest action. In at least one embodiment, the supervisory MCU can include at least one of a DLA or a GPU suitable for running one or more neural networks with associated memory. In at least one embodiment, the supervisory MCU can include and / or be included as a component of one or more SoCs 1004.

In at least one embodiment, the auxiliary computer may use classical computer vision rules (if-then), and the presence of one or more neural networks in the supervisory MCU may improve reliability, safety, and performance. For example, in at least one embodiment, the diverse implementations and intentional non-identity make the entire system more fault-tolerant, especially for failures caused by software (or software-hardware interface) functions. For example, in at least one embodiment, if there is a software vulnerability or bug in the software running on the main computer, and the non-identical software code running on the auxiliary computer provides a consistent overall result, the supervisory MCU can have greater confidence that the overall result is correct and that the vulnerability in the software or hardware on the main computer did not cause a significant error.

[0248] In at least one embodiment, the output of the ADAS system 1038 can be fed into the primary computer's perception block and / or the primary computer's dynamic driving task block. For example, in at least one embodiment, if the ADAS system 1038 indicates a forward collision warning due to an object directly ahead, the perception block can use this information when the object is identified. In at least one embodiment, the secondary computer can have its own neural network that has been trained, as described herein, to reduce the risk of false positives.

In at least one embodiment, Figure 14 One or more systems depicted in the present invention are used to implement one or more systems and / or processes (such as in conjunction with Figures 1 to 6 those described).

[0287] Figure 15A An exemplary architecture is shown in which a plurality of GPUs 1510(1)-1510(N) are communicatively coupled to a plurality of multi-core processors 1505(1)-1505(M) via high-speed links 1540(1)-1540(N) (e.g., a bus, a point-to-point interconnect, etc.). In at least one embodiment, the high-speed links 1540(1)-1540(N) support 4GB / s, 30GB / s, 80GB / s, or higher communication throughput.

In the various figures, "N" and "M" represent positive integers, the values ​​of which may vary from figure to figure. In at least one embodiment, one or more of the plurality of GPUs 1510(1)-1510(N) include, for example, Figure 18A and Figure 18B Disclosed are one or more graphics cores (also referred to simply as "cores") 1800. In at least one embodiment, one or more graphics cores 1800 may be referred to as streaming multiprocessors ("SMs"), streaming processors ("SPs"), streaming processing units ("SPUs"), compute units ("CUs"), execution units ("EUs"), and / or slices, where a slice in this context may refer to a portion of processing resources in a processing unit (e.g., 16 cores, a ray tracing unit, a thread director, or a scheduler).

[0288] Furthermore, in at least one embodiment, two or more GPUs 1510 are interconnected via high-speed links 1529(1)-1529(2), which may be implemented using protocols / links similar to or different from those used for high-speed links 1540(1)-1540(N). Similarly, two or more multi-core processors 1505 may be connected via high-speed link 1528, which may be a symmetric multiprocessor (SMP) bus operating at 20 GB / s, 30 GB / s, 120 GB / s, or higher. Alternatively, similar protocols / links may be used (e.g., via a common interconnect fabric) to accomplish this. Figure 15A All communications between the various system components shown in .

[0289] In at least one embodiment, each multi-core processor 1505 is communicatively coupled to processor memory 1501(1)-1501(M) via memory interconnects 1526(1)-1526(M), respectively, and each GPU 1510(1)-1510(N) is communicatively coupled to GPU memory 1520(1)-1520(N) via GPU memory interconnects 1550(1)-1550(N), respectively. In at least one embodiment, memory interconnects 1526 and 1550 can utilize similar or different memory access technologies. By way of example and not limitation, processor memory 1501(1)-1501(M) and GPU memory 1520 can be volatile memory, 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 can be non-volatile memory, such as 3D XPoint or Nano-Ram. In at least one embodiment, some portion of the processor memory 1501 may be volatile memory, while another portion may be non-volatile memory (eg, using a two-level memory (2LM) hierarchy).

[0290] As described herein, although each multi-core processor 1505 and GPU 1510 can be physically coupled to a specific memory 1501, 1520, respectively, and / or a unified memory architecture can be implemented in which a virtual system address space (also referred to as an "effective address" space) is distributed among the various physical memories. For example, processor memories 1501(1)-1501(M) can each include 64GB of system memory address space, and GPU memories 1520(1)-1520(N) can each include 32GB of system memory address space, resulting in a total of 256GB of addressable memory when M=2 and N=4. Other values ​​of N and M are possible.

[0291] Figure 15B Additional details are shown for the interconnection between the multi-core processor 1507 and the graphics acceleration module 1546 according to an exemplary embodiment. In at least one embodiment, the graphics acceleration module 1546 may include one or more GPU chips integrated on a line card that is coupled to the processor 1507 via a high-speed link 1540 (e.g., a PCIe bus, NVLink, etc.). In at least one embodiment, the graphics acceleration module 1546 may alternatively be integrated on a package or chip with the processor 1507.

[0292] In at least one embodiment, the processor 1507 includes a plurality of cores 1560A-1560D (which may be referred to as "execution units"), each core having a translation lookaside buffer ("TLB") 1561A-1561D and one or more caches 1562A-1562D. In at least one embodiment, the cores 1560A-1560D may include various other components, not shown, for executing instructions and processing data. In at least one embodiment, the caches 1562A-1562D may include level 1 (L1) and level 2 (L2) caches. In addition, one or more shared caches 1556 may be included in the caches 1562A-1562D and shared by each group of cores 1560A-1560D. For example, one embodiment of the processor 1507 includes 24 cores, each core having its own L1 cache, 12 shared L2 caches, and 12 shared L3 caches. In this embodiment, two adjacent cores share one or more L2 and L3 caches. In at least one embodiment, the processor 1507 and the graphics acceleration module 1546 are connected to the system memory 1514, which may include Figure 15A Processor memory 1501(1)-1501(M) in.

[0293] In at least one embodiment, coherence is maintained for data and instructions stored in the various caches 1562A-1562D, 1556 and system memory 1514 via inter-core communication over a coherence bus 1564. In at least one embodiment, for example, each cache may have cache coherence logic / circuitry associated therewith to communicate over the coherence bus 1564 in response to detecting a read or write to a particular cache line. In at least one embodiment, a cache snooping protocol is implemented over the coherence bus 1564 to snoop cache accesses.

[0294] In at least one embodiment, proxy circuitry 1525 communicatively couples graphics acceleration module 1546 to coherence bus 1564, thereby allowing graphics acceleration module 1546 to participate in a cache coherence protocol as a peer of cores 1560A-1560D. In particular, in at least one embodiment, interface 1535 provides connectivity to proxy circuitry 1525 via high-speed link 1540, and interface 1537 connects graphics acceleration module 1546 to high-speed link 1540.

[0295] In at least one embodiment, the accelerator integrated circuit 1536 provides cache management, memory access, context management, and interrupt management services on behalf of the multiple graphics processing engines 1531(1)-1531(N) of the graphics acceleration module 1546. In at least one embodiment, the multiple graphics processing engines 1531(1)-1531(N) of the graphics acceleration module 1546 may each include a separate graphics processing unit (GPU). In at least one embodiment, the multiple graphics processing engines 1531(1)-1531(N) of the graphics acceleration module 1546 include one or more graphics cores 1800, such as in combination with Figure 18A and Figure 18B In at least one embodiment, the graphics processing engines 1531(1)-1531(N) may alternatively include different types of graphics processing engines within a GPU, such as a graphics execution unit, a media processing engine (e.g., a video encoder / decoder), a sampler, and a blit engine. In at least one embodiment, the graphics acceleration module 1546 may be a GPU having multiple graphics processing engines 1531(1)-1531(N), or the graphics processing engines 1531(1)-1531(N) may be individual GPUs integrated on a common package, line card, or chip.

[0296] In at least one embodiment, the accelerator integrated circuit 1536 includes a memory management unit (MMU) 1539 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 1514. In at least one embodiment, the MMU 1539 may also include a translation lookaside buffer ("TLB") (not shown) for caching virtual / effective to physical / real address translations. In at least one embodiment, a cache 1538 may store commands and data for efficient access by the graphics processing engines 1531(1)-1531(N). In at least one embodiment, a fetch unit 1544 may be used to keep data stored in the cache 1538 and graphics memory 1533(1)-1533(M) consistent with the core caches 1562A-1562D, 1556, and system memory 1514. As previously described, this can be implemented on behalf of cache 1538 and memory 1533(1)-1533(M) via proxy circuitry 1525 (e.g., sending updates related to modifications / accesses of cache lines on processor caches 1562A-1562D, 1556 to cache 1538 and receiving updates from cache 1538).

[0297] In at least one embodiment, a set of registers 1545 stores context data for threads executed by graphics processing engines 1531(1)-1531(N), and context management circuitry 1548 manages thread contexts. For example, context management circuitry 1548 can perform save and restore operations to save and restore contexts for various threads during context switches (e.g., where a first thread is saved and a second thread is stored so that the second thread can be executed by the graphics processing engine). For example, context management circuitry 1548 can store current register values ​​to a designated area in memory (e.g., identified by a context pointer) upon context switching. The register values ​​can then be restored upon returning to the context. In at least one embodiment, interrupt management circuitry 1547 receives and processes interrupts received from system devices.

[0298] In at least one embodiment, the MMU 1539 converts virtual / effective addresses from the graphics processing engine 1531 into real / physical addresses in the system memory 1514. In at least one embodiment, the accelerator integrated circuit 1536 supports multiple (e.g., 4, 8, 16) graphics accelerator modules 1546 and / or other accelerator devices. In at least one embodiment, the graphics accelerator module 1546 can be dedicated to a single application executing on the processor 1507, or can be shared among multiple applications. In at least one embodiment, a virtualized graphics execution environment is presented in which the resources of the graphics processing engines 1531 (1)-1531 (N) are shared with multiple applications or virtual machines (VMs). In at least one embodiment, the resources can be subdivided into "slices" that are allocated to different VMs and / or applications based on the processing requirements and priorities associated with the VMs and / or applications.

[0299] In at least one embodiment, the accelerator integrated circuit 1536 acts as a bridge to the system for the graphics acceleration module 1546 and provides address translation and system memory caching services. Additionally, in at least one embodiment, the accelerator integrated circuit 1536 can provide virtualization facilities for the host processor to manage virtualization, interrupts, and memory management for the graphics processing engines 1531(1)-1531(N).

[0300] In at least one embodiment, because the hardware resources of graphics processing engines 1531(1)-1531(N) are explicitly mapped into the real address space seen by host processor 1507, any host processor can directly address these resources using effective address values. In at least one embodiment, one function of accelerator integrated circuit 1536 is the physical separation of graphics processing engines 1531(1)-1531(N) so that they appear to the system as independent units.

[0301] In at least one embodiment, one or more graphics memories 1533(1)-1533(M) are coupled to each graphics processing engine 1531(1)-1531(N), respectively, with N=M. In at least one embodiment, graphics memories 1533(1)-1533(M) store instructions and data being processed by each graphics processing engine 1531(1)-1531(N). In at least one embodiment, graphics memories 1533(1)-1533(M) can be volatile memory, such as DRAM (including stacked DRAM), GDDR memory (e.g., GDDR5, GDDR6), or HBM, and / or can be non-volatile memory, such as 3D XPoint or Nano-Ram.

[0302] In at least one embodiment, to reduce data traffic on high-speed link 1540, biasing techniques may be used to ensure that the data stored in graphics memory 1533(1)-1533(M) is the data most frequently used by graphics processing engines 1531(1)-1531(N), and preferably is not used (at least not frequently) by cores 1560A-1560D. Similarly, in at least one embodiment, the biasing mechanism attempts to keep data needed by the cores (and preferably not needed by graphics processing engines 1531(1)-1531(N)) in caches 1562A-1562D, 1556, and system memory 1514.

[0303] Figure 15C Another exemplary embodiment is shown in which an accelerator integrated circuit 1536 is integrated within the processor 1507. In this embodiment, the graphics processing engines 1531(1)-1531(N) communicate directly with the accelerator integrated circuit 1536 via interface 1537 and interface 1535 (again, which can be any form of bus or interface protocol) over a high-speed link 1540. In at least one embodiment, the accelerator integrated circuit 1536 can perform operations related to Figure 15B The operations described above are similar to those described above, but may have higher throughput due to its close proximity to the coherence bus 1564 and caches 1562A-1562D, 1556. In at least one embodiment, the accelerator integrated circuit supports different programming models, including a process-specific 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 1536 and a programming model controlled by the graphics acceleration module 1546.

[0304] In at least one embodiment, graphics processing engines 1531(1)-1531(N) are dedicated to a single application or process under a single operating system. In at least one embodiment, a single application can funnel other application requests to graphics processing engines 1531(1)-1531(N), thereby providing virtualization within a VM / partition.

[0305] In at least one embodiment, graphics processing engines 1531(1)-1531(N) can be shared by multiple VM / application partitions. In at least one embodiment, the sharing model can use a hypervisor to virtualize graphics processing engines 1531(1)-1531(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 1531(1)-1531(N). In at least one embodiment, the operating system can virtualize graphics processing engines 1531(1)-1531(N) to provide access to each process or application.

[0306] In at least one embodiment, the graphics acceleration module 1546 or the individual graphics processing engines 1531(1)-1531(N) use a process handle to select a process element. In at least one embodiment, the process element is stored in the system memory 1514 and can be addressed using the effective address to real address translation techniques described herein. In at least one embodiment, the process handle can be an implementation-specific value that is provided to the host process when registering its context with the graphics processing engine 1531(1)-1531(N) (i.e., calling system software to add the process element to a linked list of process elements). In at least one embodiment, the lower 16 bits of the process handle can be the offset of the process element in the linked list of process elements.

[0307] Figure 15D An exemplary accelerator integrated slice 1590 is shown. In at least one embodiment, a "slice" comprises a designated portion of the processing resources of the accelerator integrated circuit 1536. In at least one embodiment, the application is an effective address space 1582 in system memory 1514, which stores a process element 1583. In at least one embodiment, the process element 1583 is stored in response to a GPU call 1581 from an application 1580 executing on the processor 1507. In at least one embodiment, the process element 1583 contains the process state of the corresponding application 1580. In at least one embodiment, the work descriptor (WD) 1584 contained in the process element 1583 can be a single job requested by the application, or can contain a pointer to a job queue. In at least one embodiment, the WD 1584 is a pointer to a job request queue in the effective address space 1582 of the application.

[0308] In at least one embodiment, the graphics acceleration module 1546 and / or the individual graphics processing engines 1531(1)-1531(N) can be shared by all processes or a subset of processes in the system. In at least one embodiment, infrastructure can be included for setting process state and sending WD 1584 to the graphics acceleration module 1546 to start a job in a virtualized environment.

[0309] In at least one embodiment, the process-specific programming model is implementation-specific. In at least one embodiment, in this model, a single process owns a graphics acceleration module 1546 or an individual graphics processing engine 1531. In at least one embodiment, when a graphics acceleration module 1546 is owned by a single process, the hypervisor initializes the accelerator integrated circuit 1536 for the owned partition, and when a graphics acceleration module 1546 is assigned, the operating system initializes the accelerator integrated circuit 1536 for the owned process.

[0310] In operation, in at least one embodiment, a WD fetch unit 1591 in the accelerator integrated slice 1590 fetches a next WD 1584, which includes an indication of work to be performed by one or more graphics processing engines of the graphics acceleration module 1546. In at least one embodiment, data from the WD 1584 may be stored in registers 1545 and used by the MMU 1539, interrupt management circuitry 1547, and / or context management circuitry 1548, as shown. For example, one embodiment of the MMU 1539 includes segment / page walk circuitry for accessing segment / page tables 1586 within the OS virtual address space 1585. In at least one embodiment, the interrupt management circuitry 1547 may process interrupt events 1592 received from the graphics acceleration module 1546. In at least one embodiment, when performing graphics operations, effective addresses 1593 generated by the graphics processing engines 1531(1)-1531(N) are converted to real addresses by the MMU 1539.

[0311] In at least one embodiment, registers 1545 are replicated for each graphics processing engine 1531(1)-1531(N) and / or graphics acceleration module 1546, and these registers 1545 can be initialized by a hypervisor or operating system. In at least one embodiment, each of these replicated registers can be included in an accelerator integration slice 1590. Exemplary registers that can be initialized by a hypervisor are shown in Table 1.

[0312] Table 1 - Registers initialized by the hypervisor

[0313]

[0314]

[0315] Example registers that may be initialized by the operating system are shown in Table 2.

[0316] Table 2 - Registers initialized by the operating system

[0317]

[0318] In at least one embodiment, each WD 1584 is specific to a particular graphics acceleration module 1546 and / or graphics processing engine 1531(1)-1531(N). In at least one embodiment, it contains all the information needed by the graphics processing engine 1531(1)-1531(N) to complete its work, or it may be a pointer to a memory location where an application has set up a command queue for work to be done.

[0319] Figure 15E 1596 virtualizes the graphics acceleration module engine for the operating system 1595.

[0320] 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 1546. In at least one embodiment, there are two programming models where the graphics acceleration module 1546 is shared by multiple processes and partitions, namely, time-sliced ​​sharing and graphics-directed sharing.

[0321] In at least one embodiment, in this model, the hypervisor 1596 owns the graphics acceleration module 1546 and makes its functionality available to all operating systems 1595. In at least one embodiment, for the graphics acceleration module 1546 to support virtualization through the hypervisor 1596, the graphics acceleration module 1546 may adhere to certain requirements, such as (1) the application's job requests must be autonomous (i.e., no state needs to be maintained between jobs), or the graphics acceleration module 1546 must provide a context save and restore mechanism, (2) the graphics acceleration module 1546 guarantees that the application's job requests are completed within a specified amount of time, including any transition errors, or the graphics acceleration module 1546 provides the ability to preempt job processing, and (3) the graphics acceleration module 1546 must ensure fairness between processes when operating in a directed shared programming model.

[0322] In at least one embodiment, the application 1580 is required to make an operating system 1595 system call using a graphics acceleration module type, a work descriptor (WD), an authority mask register (AMR) value, and a context save / restore region pointer (CSRP). In at least one embodiment, the graphics acceleration module type describes the target acceleration functionality 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 formatted specifically for the graphics acceleration module 1546 and can take the form of a graphics acceleration module 1546 command, an effective address pointer to a user-defined structure, an effective address pointer to a command queue, or any other data structure that describes the work to be performed by the graphics acceleration module 1546.

[0323] 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 the application that set the AMR. In at least one embodiment, if the implementation of the accelerator integrated circuit 1536 (not shown) and the graphics acceleration module 1546 does not support the User Authority Mask Override 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 1596 may selectively apply the current AMR value before placing the AMR into the process element 1583. In at least one embodiment, the CSRP is one of the registers 1545 that contains the effective address of an area in the application's effective address space 1582 for the graphics acceleration module 1546 to save and restore context state. In at least one embodiment, this pointer is optional if state does not need to be saved between jobs or when a job is preempted. In at least one embodiment, the context save / restore area may be fixed system memory.

[0324] Upon receiving the system call, the operating system 1595 can verify that the application 1580 has been registered and granted permission to use the graphics acceleration module 1546. Then, in at least one embodiment, the operating system 1595 calls the hypervisor 1596 using the information shown in Table 3.

[0325] Table 3 - OS to Hypervisor Call Parameters

[0326]

[0327]

[0328] In at least one embodiment, upon receiving the hypervisor call, hypervisor 1596 verifies that operating system 1595 has registered and been granted permission to use graphics acceleration module 1546. Then, in at least one embodiment, hypervisor 1596 places process element 1583 into a linked list of process elements of the corresponding type of graphics acceleration module 1546. In at least one embodiment, the process element may include the information shown in Table 4.

[0329] Table 4 - Process element information

[0330]

[0331] In at least one embodiment, the hypervisor initializes the plurality of accelerator integrated slice 1590 registers 1545 .

[0332] like Figure 15F As shown, in at least one embodiment, a unified memory is used that is addressable via a common virtual memory address space for accessing physical processor memory 1501(1)-1501(N) and GPU memory 1520(1)-1520(N). In this implementation, operations executed on GPUs 1510(1)-1510(N) utilize the same virtual / effective memory address space to access processor memory 1501(1)-1501(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 1501(1), a second portion is allocated to second processor memory 1501(N), a third portion is allocated to GPU memory 1520(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 1501 and GPU memory 1520, thereby allowing any processor or GPU to access any physical memory using a virtual address that maps to that memory.

[0333] In at least one embodiment, bias / coherency management circuitry 1594A-1594E within one or more MMUs 1539A-1539E ensures cache coherency between the caches of one or more host processors (e.g., 1505) and GPU 1510 and implements biasing techniques that indicate the physical memory where certain types of data should be stored. Figure 15F Multiple instances of bias / coherence management circuits 1594A- 1594E are shown in , but bias / coherence circuits may be implemented within an MMU of one or more host processors 1505 and / or within an accelerator integrated circuit 1536 .

[0334] One embodiment allows GPU memory 1520 to be mapped as part of system memory and accessed using shared virtual memory (SVM) technology without the performance drawbacks associated with system-wide cache coherence. In at least one embodiment, the ability to access GPU memory 1520 as system memory without the heavy cache coherence overhead provides a favorable operating environment for GPU offloading. In at least one embodiment, this arrangement allows host processor 1505 software to set operands and access computation results without the overhead of traditional I / O DMA data copying. In at least one embodiment, such traditional 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 1520 without cache coherence overhead can be critical to the execution time of offloaded computations. In at least one embodiment, for example, in situations with heavy streaming write-to-memory traffic, cache coherence overhead can significantly reduce the effective write bandwidth seen by GPU 1510. In at least one embodiment, the efficiency of operand setup, result access, and GPU computation can play a role in determining the effectiveness of GPU offloading.

[0335] 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 can be a page-granular structure (e.g., controlled at the granularity of a memory page) that includes 1 or 2 bits per GPU additional memory page. In at least one embodiment, the bias table can be implemented in a stolen memory range of one or more GPU memories 1520, with or without a bias cache in GPU 1510 (e.g., for caching frequently / recently used entries in the bias table). Alternatively, in at least one embodiment, the entire bias table can be maintained within the GPU.

[0336] In at least one embodiment, the bias table entry associated with each access to GPU-attached memory 1520 is accessed before the GPU memory is actually accessed, resulting in the following operations. In at least one embodiment, local requests from GPU 1510 whose pages are found in the GPU bias are forwarded directly to the corresponding GPU memory 1520. In at least one embodiment, local requests from the GPU whose pages are found in the host bias are forwarded to processor 1505 (e.g., via the high-speed link described herein). In at least one embodiment, requests from processor 1505 that find the requested page in the host processor bias complete the request similarly to a normal memory read. Alternatively, requests directed to GPU-biased pages can be forwarded to GPU 1510. In at least one embodiment, if the GPU is not currently using the page, the GPU can migrate the page to the host processor bias. In at least one embodiment, the bias state of a page can be changed via a software-based mechanism, a hardware-assisted software-based mechanism, or, in a limited set of cases, a purely hardware-based mechanism.

[0337] In at least one embodiment, a mechanism for changing bias states employs an API call (e.g., OpenCL), which in turn calls a device driver for the GPU, which in turn sends a message (or queues a command descriptor) to the GPU, directing the GPU to change the bias state and, in some migrations, to perform a cache flush operation in the host. In at least one embodiment, the cache flush operation is used for migrations from host processor 1505 bias to GPU bias, but not for the reverse migration.

[0338] In at least one embodiment, cache coherence is maintained by temporarily rendering GPU-biased pages that cannot be cached by host processor 1505. In at least one embodiment, to access these pages, processor 1505 may request access from GPU 1510, which may or may not immediately grant access. Therefore, in at least one embodiment, to reduce communication between processor 1505 and GPU 1510, it is beneficial to ensure that GPU-biased pages are the pages required by the GPU and not the host processor 1505, and vice versa.
