[0001] At least one embodiment relates to processing resources for using one or more neural networks to generate one or more three-dimensional (3D) models of an object from text based at least in part on one or more images of an object obtained from two or more cameras placed at different angles. BACKGROUND
[0002] Using a neural network to generate three-dimensional (3D) models can sometimes lead to inaccuracies if training data (e.g., images) used to train the neural network lack information due to occlusions, restricted angles, corrupted data, and the like. For example, the training data may only contain a frontal view of an object from an image used to train the neural network. Therefore, improvements can be made to better train a neural network and generate 3D models.

[0003] In at least one embodiment, systems and methods implemented in accordance with this disclosure are used to use software to train one or more neural networks to generate a three-dimensional (3D) model from an input text description, wherein the one or more neural networks are trained using multiple viewpoints of an object. In at least one embodiment, systems and methods implemented in accordance with this disclosure are used to use software to train one or more neural networks to generate a three-dimensional (3D) model from an input image.In at least one embodiment, the one or more neural networks generate the 3D model using multiple images from different viewpoints, and during training, the loss is calculated based on whether the 3D model simultaneously matches the multiple images.
[0004] In at least one embodiment, one or more neural networks generate one or more 3D models from text without bias in shape and appearance. In at least one embodiment, the one or more 3D models are generated by defusing a text-to-image diffusion model. In at least one embodiment, a dataset of image-text pairs is created, where the images are rendered from a corpus of 3D computer-aided design (CAD) models. In at least one embodiment, the diffusion model is refined to generate N viewpoints of the same object simultaneously, where the N viewpoints are specific angles apart, organized as tiled images. In at least one embodiment, when the fine-tuned diffusion model is used as a critique: "critic") is used for text-to-3D generation, the critique ensures that rendered images from any set of N viewpoints that are similar and relatively spaced should fall into a common distribution of images at those viewpoints. In at least one embodiment, this ensures that the shape and appearance of the viewpoints are always rendered and modeled together, resulting in viewpoint-decoupled text-to-3D generation.
[0005] In at least one embodiment, a text-to-3D generator generates one or more 3D representations from textual descriptions of an object using one or more images of an object captured by two or more cameras at different angles. In at least one embodiment, a textual description is input text (e.g., text strings, words, speech-to-text generator results, images, etc.) entered by a user. In at least one embodiment, a text-to-3D generator is an image-to-3D generator and generates one or more 3D representations from image input by a user. In at least one embodiment, a text-to-3D generator includes one or more neural networks that train a text-to-image diffusion model on a dataset including a dataset of image-text pairs.In at least one embodiment, the text-to-image diffusion model is de-empowered (e.g., with respect to one or more particular viewpoints, such as frontal views that predominantly depict faces) by retraining it on a dataset comprising one or more images of one or more objects obtained from two or more cameras positioned at different angles.
[0006] In at least one embodiment, the desensitized dataset for retraining comprises one or more digitally rotatable 3D CAD representations of two or more images of one or more objects. In at least one embodiment, another dataset of image-text pairs is created using images rendered from a corpus of 3D CAD models. In at least one embodiment, the two or more images comprise digitally rotatable 3D CAD representations with N viewpoints, where N is two or more. In at least one embodiment, an N-viewpoint CAD representation is acquired from cameras positioned substantially in a plane surrounding one or more objects, referred to as a target. In at least one embodiment, the cameras are evenly spaced and occupy the plane in its entirety. In at least one embodiment, the two or more images are combined as one (desensitized,: "debiased"]) collage. In at least one embodiment, the collage is linked to descriptive text as an image-text pair. In at least one embodiment, the image-text pair is converted into a digitally rotatable 3D CAD representation of the target.
[0007] In at least one embodiment, the diffusion model acts as a critique for training images to train the text-to-3D generator. In at least one embodiment, the 2D diffusion model requires only relative angular offsets, which are known during collage assembly. In at least one embodiment, the 2D diffusion model provides guidance from multiple viewpoints simultaneously during 3D asset optimization. In at least one embodiment, the 2D diffusion model interprets these views as coming from the same underlying object.
[0008] In at least one embodiment, the text-to-3D generator generates a 3D model from an unbiased collage. In at least one embodiment, the diffusion model evaluates the 3D model. In at least one embodiment, the diffusion model is fine-tuned to generate N viewpoints of the target object simultaneously. In at least one embodiment, the diffusion model indicates which versions of the generated model are of high confidence. In at least one embodiment, the diffusion model is trained to select only 3D models without artifacts, thereby reducing artifacts if the text-to-3D generator were to attempt to generate a 3D model from a set of images taken at random times and / or from random viewpoints.
[0009] In at least one embodiment, a loss function is used to compare the 3D object representation generated by the text-to-3D generator with a ground-truth representation. In at least one embodiment, the weights of the text-to-3D generator are adjusted according to the output of the loss function. In at least one embodiment, a loss function includes mean square error, regression, classification, autoencoder, and diffusion model loss, etc.
[0010] In at least one embodiment, one or more neural networks are trained to generate models (e.g., predictions or inferring information) from input data that includes, but is not limited to, image data. In at least one embodiment, one or more neural networks generate 3D models using multiple images captured using photo stocks or randomly from cameras from different viewpoints and / or at different times (e.g., models created using view-dependent prompts). In this way, 3D models can be constructed rather than using separate networks for different models. In at least one embodiment, a model is constructed using training data specifically designed for 3D modeling and with minimal bias toward a particular viewpoint.In at least one embodiment, a model is further constructed using training data simultaneously collected from certain random viewpoints. In at least one embodiment, to improve the ability of a neural network to generate 3D models using the techniques described herein, a processor having one or more circuits is caused to generate information about the one or more objects during training of a neural network.
[0011] Neural networks that generate 3D models of objects from text generate 3D models with parts of an object that shouldn't be present, such as a nose on one side of a face. This is because neural networks are trained by generating 3D models, using the 3D model to generate a 2D image of an object from a viewpoint for which there is a ground-truth 2D image from a same viewpoint, and adjusting the weights based on the loss measure of how well the 2D images match. However, ground-truth 2D images are aligned to the same viewpoints (meaning neural networks learn parts of objects from those viewpoints) and are not trained with information that indicates how different viewpoints should appear at the same time relative to each other (for example, that if one viewpoint has a nose, another viewpoint shouldn't have an additional nose).In at least one embodiment, the techniques described herein train a neural network to generate a 3D model from text, wherein the neural network is trained using multiple viewpoints of the object.
[0012] The preceding and following descriptions describe various techniques. For explanatory purposes, specific configurations and details are presented to provide a thorough understanding of possible ways to implement the techniques. However, it is also understood that the techniques described below may be implemented in various configurations without specific details. Furthermore, well-known features may be omitted or simplified to avoid obscuring the described techniques.

In at least one embodiment, the graphics acceleration module 1646 may be a GPU with a plurality of graphics processing engines 1631(1)-1631(N), or the graphics processing engines 1631(1)-1631(N) may be individual GPUs integrated on a common package, line card, or die.
[0236] In at least one embodiment, accelerator integration circuitry 1636 includes a memory management unit (MMU) 1639 for performing various memory management functions, such as virtual-to-physical memory translations (also referred to as effective-to-real memory translations) and memory access protocols for accessing system memory 1614. In at least one embodiment, MMU 1639 may also include a translation lookaside buffer (TLB) (not shown) to cache virtual / effective to physical / real address translations. In at least one embodiment, a cache 1638 may store instructions and data for efficient access by graphics processing engines 1631(1)-1631(N).In at least one embodiment, the data stored in cache 1638 and graphics memories 1633(1)-1633(M) is kept coherent with core caches 1662A-1662D, 1656, and system memory 1614, possibly using a fetch unit 1644. As noted, this may be done via proxy circuitry 1625 on behalf of cache 1638 and memories 1633(1)-1633(M) (e.g., sending updates to cache 1638 regarding changes / accesses to cache lines in processor caches 1662A-1662D, 1656 and receiving updates from cache 1638).
[0237] In at least one embodiment, a set of registers 1645 stores context data for threads executed by graphics processing engines 1631(1)-1631(N), and context management circuitry 1648 manages thread contexts. For example, context management circuitry 1648 may perform save and restore operations to save and restore the contexts of different threads during a context switch (e.g., when a first thread is saved and a second thread is saved to allow a second thread to be executed by a graphics processing engine). For example, during a context switch, context management circuitry 1648 may store current register values in a specific region of memory (e.g., to be identified by a context pointer). The register values may then be restored upon return to a context.In at least one embodiment, an interrupt management circuit 1647 receives and processes interrupts received from system devices.
[0238] In at least one embodiment, virtual / effective addresses from a graphics processing engine 1631 are translated by the MMU 1639 into real / physical addresses in system memory 1614. In at least one embodiment, the accelerator integration circuit 1636 supports multiple (e.g., 4, 8, 16) graphics acceleration modules 1646 and / or other acceleration devices. In at least one embodiment, the graphics acceleration module 1646 may be dedicated to a single application executing on the processor 1607, or it may be shared among multiple applications. In at least one embodiment, a virtualized graphical execution environment is depicted in which the resources of the graphics processing engines 1631(1)-1631(N) are shared among multiple applications or virtual machines (VMs).In at least one embodiment, the resources may be divided 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.
[0239] In at least one embodiment, accelerator integration circuitry 1636 acts as a bridge to a system for graphics acceleration module 1646 and provides address translation and system memory caching services. Furthermore, in at least one embodiment, accelerator integration circuitry 1636 may provide virtualization facilities to a host processor to manage the virtualization of graphics processing engines 1631(1)-1631(N), interrupts, and memory management.
[0240] Because, in at least one embodiment, the hardware resources of graphics processing engines 1631(1)-1631(N) are explicitly mapped to a real address space seen by host processor 1607, each host processor can directly address these resources via an effective address value. In at least one embodiment, a function of accelerator integration circuitry 1636 is to physically separate graphics processing engines 1631(1)-1631(N) so that they appear to a system as independent entities.
[0241] In at least one embodiment, one or more graphics memories 1633(1)-1633(M) are coupled to each of the graphics processing engines 1631(1)-1631(N), where N=M. In at least one embodiment, the graphics memories 1633(1)-1633(M) store instructions and data processed by each of the graphics processing engines 1631(1)-1631(N). In at least one embodiment, the graphics memories 1633(1)-1633(M) may be volatile memories such as DRAMs (including stacked DRAMs), GDDR memories (e.g., GDDR5, GDDR6), or HBM, and / or may be non-volatile memories such as 3D XPoint or Nano-RAM.
[0242] In at least one embodiment, to reduce data traffic over high-speed interconnect 1640, bias techniques may be used to ensure that the data stored in graphics memories 1633(1)-1633(M) is data most frequently used by graphics processing engines 1631(1)-1631(N) and preferably not used by cores 1660A-1660D (at least not frequently). Similarly, in at least one embodiment, a bias mechanism attempts to keep data needed by cores (and preferably not by graphics processing engines 1631(1)-1631(N)) in caches 1662A-1662D, 1656, and system memory 1614.
[0243] Fig. 16C shows another exemplary embodiment in which accelerator integration circuitry 1636 is integrated into processor 1607. In this embodiment, graphics processing engines 1631(1)-1631(N) communicate directly over high-speed interconnect 1640 with accelerator integration circuitry 1636 via interface 1637 and interface 1635 (which may again be any form of bus or interface protocol). In at least one embodiment, accelerator integration circuitry 1636 may perform operations similar to those described in Fig. 16B, but possibly with higher throughput due to its proximity to the coherence bus 1664 and caches 1662A-1662D, 1656. In at least one embodiment, an accelerator integration circuit supports different programming models, including a dedicated process programming model (without graphics acceleration module virtualization) and shared programming models (with virtualization), which may include programming models controlled by the accelerator integration circuit 1636 and programming models controlled by the graphics acceleration module 1646.
[0244] In at least one embodiment, graphics processing engines 1631(1)-1631(N) are dedicated to a single application or process under a single operating system. In at least one embodiment, a single application can forward requests from other applications to graphics processing engines 1631(1)-1631(N), thus enabling virtualization within a VM / partition.
[0245] In at least one embodiment, the graphics processing engines 1631(1)-1631(N) may be shared between multiple VM / application partitions. In at least one embodiment, shared models may use a system hypervisor to virtualize the graphics processing engines 1631(1)-1631(N) to allow access by any operating system. In at least one embodiment, for systems with a single partition without a hypervisor, the graphics processing engines 1631(1)-1631(N) are owned by an operating system. In at least one embodiment, an operating system may virtualize the graphics processing engines 1631(1)-1631(N) to allow access to any process or application.
[0246] In at least one embodiment, the graphics acceleration module 1646 or an individual graphics processing engine 1631(1)-1631(N) selects a process element using a process handle. In at least one embodiment, process elements are stored in system memory 1614 and are addressable using an effective address to real address translation technique described herein. In at least one embodiment, a process handle may be an implementation-specific value provided to a host process when it registers its context with the graphics processing engine 1631(1)-1631(N) (i.e., when it calls system software to add a process element to a linked process element list). In at least one embodiment, the lower 16 bits of a process handle may be an offset of a process element within a process element list.
[0247] Fig. 16D shows an example accelerator integration slice 1690. In at least one embodiment, a "slice" comprises a particular portion of the processing resources of accelerator integration circuitry 1636. In at least one embodiment, an application stores process elements 1683 in an effective address space 1682 in system memory 1614. In at least one embodiment, process elements 1683 are stored in response to GPU calls 1681 from applications 1680 executing on processor 1607. In at least one embodiment, a process element 1683 contains the state of the corresponding application 1680. In at least one embodiment, a work description (WD) 1684 contained in process element 1683 may be a single job requested by an application or may contain a pointer to a queue of jobs.In at least one embodiment, the WD 1684 is a pointer to a job request queue in the effective address space 1682 of an application.
[0248] In at least one embodiment, the graphics acceleration module 1646 and / or individual graphics processing engines 1631(1)-1631(N) may be shared by all or a subset of the processes in a system. In at least one embodiment, an infrastructure for establishing process states and sending a WD 1684 to a graphics acceleration module 1646 to start a job in a virtualized environment may be included.
[0249] In at least one embodiment, a programming model for dedicated processes is implementation-specific. In at least one embodiment, in this model, a single process owns the graphics acceleration module 1646 or an individual graphics processing engine 1631. In at least one embodiment, when the graphics acceleration module 1646 is owned by a single process, a hypervisor initializes the accelerator integration circuit 1636 for an owning partition, and an operating system initializes the accelerator integration circuit 1636 for an owning process when the graphics acceleration module 1646 is allocated.
[0250] In at least one embodiment, a WD fetch unit 1691 in accelerator integration slice 1690 operatively fetches the next WD 1684, which includes an indication of the work to be performed by one or more graphics processing engines of graphics acceleration module 1646. In at least one embodiment, the data from WD 1684 may be stored in registers 1645 and used by MMU 1639, interrupt management circuitry 1647, and / or context management circuitry 1648, as shown. For example, one embodiment of MMU 1639 includes segment / page browsing circuitry for accessing segment / page tables 1686 within an OS virtual address space 1685. In at least one embodiment, circuitry 1647 may process interrupt events 1692 received from graphics acceleration module 1646.In at least one embodiment, when performing graphics operations, an effective address 1693 generated by a graphics processing engine 1631(1)-1631(N) is translated into a real address by the MMU 1639.
[0251] In at least one embodiment, registers 1645 are duplicated for each graphics processing engine 1631(1)-1631(N) and / or each graphics acceleration module 1646 and may be initialized by a hypervisor or an operating system. In at least one embodiment, each of these duplicated registers may be included in an accelerator integration slice 1690. Example registers that may be initialized by a hypervisor are shown in Table 1. Table 1 - Initialized hypervisor registers Register # Beschreibung 1 Slice-Steuerregister 2 Real Address (RA) Pointer to the area for scheduled processes 3 Authority mask override register 4 Interrupt vector table entry offset 5 Interrupt vector table entry boundary 6 Condition register 7 Logical partition ID 8 Real Address (RA) Hypervisor Accelerator Workload Set Pointer 9 Memory description register
[0252] Example registers that can be initialized by an operating system are shown in Table 2. Table 2 - Initialized operating system registers Register # Description 1 Process and thread identification 2 Effective Address (EA) Context Store / Restore Pointer 3 Virtual Address (VA) Accelerator Workload Set Pointer 4 Virtual Address (VA) Pointer to memory segment table 5 Authority mask 6 Job description
[0253] In at least one embodiment, each WD 1684 is specific to a particular graphics acceleration module 1646 and / or graphics processing engines 1631(1)-1631(N). In at least one embodiment, it contains all the information required by a graphics processing engine 1631(1)-1631(N) to perform work, or it may be a pointer to a memory location where an application has established a command queue of work to be performed.
[0254] Fig.16E shows additional details for an exemplary embodiment of a joint model. This embodiment includes a real hypervisor address space 1698 in which a process element list 1699 is stored. In at least one embodiment, the real hypervisor address space 1698 is accessible via a hypervisor 1696 that virtualizes graphics acceleration engine engines for the operating system 1695.
[0255] In at least one embodiment, shared programming models allow all or a subset of processes from all or a subset of partitions in a system to use a graphics acceleration module 1646. In at least one embodiment, there are two programming models where the graphics acceleration module 1646 is shared among multiple processes and partitions: time-slice sharing and graphics sharing.
[0256] In at least one embodiment, in this model, the system hypervisor 1696 has the graphics acceleration module 1646 and makes its functionality available to all operating systems 1695. In at least one embodiment, a graphics acceleration module 1646 may meet certain requirements to support virtualization by the system hypervisor 1696, such as (1) the job request of an application must be autonomous (i.e.the state does not need to be maintained between jobs), or the graphics acceleration module 1646 must provide a mechanism for saving and restoring the context, (2) the graphics acceleration module 1646 guarantees that an application's job request will be completed in a specified amount of time, including any translation errors, or the graphics acceleration module 1646 provides the ability to preempt processing of a job, and (3) the graphics acceleration module 1646 must be guaranteed fairness between processes when operating in a directed joint programming model.
[0257] In at least one embodiment, application 1680 must make a system call to operating system 1695 with a graphics acceleration module type, a work description (WD), an authority mask register value (AMR), and a context save / restore pointer (CSRP). In at least one embodiment, the graphics acceleration module type describes a targeted acceleration function for a system call. In at least one embodiment, the graphics acceleration module type may be a system-specific value. In at least one embodiment, WD is formatted specifically for graphics acceleration module 1646 and may be in the form of a graphics acceleration module 1646 instruction, a pointer to the effective address of a user-defined structure, a pointer to the effective address of an instruction queue, or another data structure describing the work to be performed by graphics acceleration module 1646.
[0258] In at least one embodiment, an AMR value is an AMR state to be used for a current process. In at least one embodiment, a value passed to an operating system is similar to an application setting an AMR. In at least one embodiment, if accelerator integration circuitry 1636 (not shown) and graphics acceleration module 1646 do not support an authority mask override register (UAMOR), an operating system may apply a current UAMOR value to an AMR value before passing an AMR in a hypervisor call. In at least one embodiment, hypervisor 1696 may optionally apply a current authority mask override register (AMOR) value before placing an AMR into process element 1683.In at least one embodiment, CSRP is one of the registers 1645 that contains an effective address of a region in an application's effective address space 1682 for the graphics acceleration module 1646 to save and restore state. In at least one embodiment, this pointer is optional if no state needs to be saved between jobs or if a job aborts prematurely. In at least one embodiment, the context save / restore region may be anchored in system memory.
[0259] Upon receiving a system call, the operating system 1695 may verify whether the application 1680 has and has been granted permission to use the graphics acceleration module 1646. In at least one embodiment, the operating system 1695 then invokes the hypervisor 1696 with the information shown in Table 3. Table 3 - Parameters for calling the operating system to the hypervisor Parameters # Description 1 A job description (WD) 2 An authority mask register (AMR) value (possibly masked) 3 An effective address (EA) Context save / restore pointer (CSRP) 4 A process ID (PID) and optionally a thread ID (TID) 5 A virtual address (VA) accelerator utilization set pointer (AURP) 6 Virtual address of the pointer to the memory segment table (SSTP) 7 A logical interrupt service number (LISN)
[0260] In at least one embodiment, upon receiving a hypervisor call, hypervisor 1696 checks whether operating system 1695 has and has been granted permission to use graphics acceleration module 1646. In at least one embodiment, hypervisor 1696 then places process element 1683 in a process element list for a corresponding type of graphics acceleration module 1646. In at least one embodiment, a process element may include the information shown in Table 4. Table 4 - Process element information Item # Description 1 A job description (WD) 2 An Authority Mask Register (AMR) value (possibly masked). 3 An effective address (EA) Context save / restore pointer (CSRP) 4 A process ID (PID) and optionally a thread ID (TID) 5 A virtual address (VA) accelerator utilization set pointer (AURP) 6 Virtual address of the pointer to the memory segment table (SSTP) 7 A logical interrupt service number (LISN) 8 Interrupt vector table derived from hypervisor call parameters 9 A status register value (SR) 10 A logical partition ID (LPID) 11 A pointer to the hypervisor's accelerator utilization set with RealAddress (RA) 12 Memory Description Register (SDR)
[0261] In at least one embodiment, the hypervisor initializes a plurality of accelerator integration slice 1690 registers 1645.
[0262] As in Fig.16F, in at least one embodiment, a unified memory addressable via a common virtual memory address space is used to access physical processor memories 1601(1)-1601(N) and GPU memories 1620(1)-1620(N). In this implementation, operations performed on GPUs 1610(1)-1610(N) use the same virtual / effective address space to access processor memories 1601(1)-1601(M) and vice versa, simplifying programmability. In at least one embodiment, a first portion of a virtual / effective address space is mapped to processor memory 1601(1), a second portion is mapped to second processor memory 1601(N), a third portion is mapped to GPU memory 1620(1), and so on.In at least one embodiment, this distributes a total virtual / effective memory space (sometimes referred to as effective address space) across each of the processor memories 1601 and GPU memories 1620, such that each processor or GPU can access each physical memory with a virtual address associated with that memory.
[0263] In at least one embodiment, the bias / coherence management circuitry 1694A-1694E within one or more MMUs 1639A-1639E ensures cache coherence between the caches of one or more host processors (e.g., 1605) and GPUs 1610 and implements bias techniques that indicate in which physical memories certain data types should be stored. In at least one embodiment, while multiple instances of the bias / coherence management circuitry 1694A-1694E in Fig.16F, the bias / coherence circuitry may be implemented within an MMU of one or more host processors 1605 and / or within the accelerator integration circuitry 1636.
[0264] In one embodiment, GPU memories 1620 may be mapped as part of system memory and accessed using shared virtual memory (SVM) technology without the performance penalty associated with full system cache coherence. In at least one embodiment, the ability to access GPU memories 1620 as system memory without burdensome cache coherence overhead provides a favorable operating environment for GPU offload. In at least one embodiment, this arrangement allows host processor 1605 software to set operands and access computation results without the overhead of traditional I / O DMA data copies. In at least one embodiment, such traditional copies involve driver calls, interrupts, and memory-mapped I / O (MMIO) accesses, all of which are inefficient compared to simple memory accesses.In at least one embodiment, the ability to access GPU memory 1620 without cache coherence overheads may be critical to the execution time of an offloaded computation. For example, in at least one embodiment, the cache coherence overhead may significantly reduce the effective write bandwidth of a graphics processor 1610 in cases with significant streaming write memory traffic. In at least one embodiment, operand construction efficiency, result access efficiency, and GPU computation efficiency may play a role in determining the effectiveness of a GPU offload.
[0265] In at least one embodiment, the selection of the GPU bias and the host processor bias is controlled by a bias tracker data structure. For example, in at least one embodiment, a bias table may be used, which may be a page-granular structure (e.g., controlled at the granularity of a memory page) comprising 1 or 2 bits per GPU-attached memory page. In at least one embodiment, a bias table may be implemented in a stolen memory region of one or more GPU memories 1620, with or without a bias cache in a GPU 1610 (e.g., to cache frequently / recently used bias table entries). Alternatively, in at least one embodiment, an entire bias table may be maintained in a GPU.
[0266] In at least one embodiment, a bias table entry associated with each access to GPU-attached memory 1620 is accessed prior to the actual GPU memory access, causing the following operations. In at least one embodiment, local requests from a GPU 1610 that find their page GPU-biased are forwarded directly to a corresponding GPU memory 1620. In at least one embodiment, local requests from a GPU that find their page in the host's bias are forwarded to processor 1605 (e.g., over a high-speed connection, as described herein). In at least one embodiment, requests from processor 1605 that find a requested page in the host processor's bias complete a request like a normal memory read.Alternatively, requests directed to a GPU-biased page may be forwarded to a GPU 1610. In at least one embodiment, a GPU may then forward a page to a host processor bias if it is not currently using the page. In at least one embodiment, a page's bias state may be changed either by a software-based mechanism, a hardware-assisted software-based mechanism, or, for a limited number of cases, a purely hardware-based mechanism.
[0267] In at least one embodiment, a mechanism for changing the bias state uses an API call (e.g., OpenCL), which in turn calls a graphics processor's device driver, which in turn sends a message (or command descriptor) to a graphics processor instructing it to change a bias state and, on some transitions, perform a cache flush operation in a host. In at least one embodiment, a cache flush operation is used for a transition from the host processor 1605 bias to the GPU bias, but not for an opposite transition.
[0268] In at least one embodiment, cache coherence is maintained by temporarily making GPU-biased pages uncacheable by host processor 1605. In at least one embodiment, to access these pages, processor 1605 may request access from GPU 1610, which may or may not grant access immediately. Therefore, in at least one embodiment, to reduce communication between processor 1605 and GPU 1610, it is advantageous to ensure that GPU-biased pages are those required by a GPU but not by the host processor 1605, and vice versa.
[0269] Hardware structure(s) 815 are used to carry out one or more embodiments. Details of a hardware structure (or more hardware structures) 815 may be described herein in connection with Fig. 8A and / or 8B must be specified.

In at least one embodiment, graphics processor 1810 may execute different shader programs via separate logic, such that vertex processor 1805 is optimized to perform operations for vertex shader programs, while one or more fragment processors 1815A-1815N perform fragment (e.g., pixel) shading operations for fragment or pixel shader programs. In at least one embodiment, the vertex processor 1805 performs a vertex processing stage of a 3D graphics pipeline and generates primitives and vertex data.In at least one embodiment, fragment processor(s) 1815A-1815N use the primitive and vertex data generated by vertex processor 1805 to generate a framebuffer displayed on a display device.
