[0276] In one embodiment, each WD 1584 is specific to a particular graphics acceleration module 1546 and/or graphics processing engines 1531-1532, N. It contains all information required by a graphics processing engine 1531-1532, N to do work or it can be a pointer to a memory location where an application has set up a command queue of work to be completed. [0277] FIG.15E illustrates additional details for one exemplary embodiment of a shared model. This embodiment includes a hypervisor real address space 1598 in which a process element list 1599 is stored. Hypervisor real address space 1598 is accessible via a hypervisor 1596 which virtualizes graphics acceleration module engines for operating system 1595. [0278] In at least one embodiment, shared programming models allow for all or a subset of processes from all or a subset of partitions in a system to use a graphics acceleration module 1546. There are two programming models where graphics acceleration module 1546 is shared by multiple processes and partitions: time-sliced shared and graphics directed shared. [0279] In this model, system hypervisor 1596 owns graphics acceleration module 1546 and makes its function available to all operating systems 1595. For a graphics acceleration module 1546 to support virtualization by system hypervisor 1596, graphics acceleration module 1546 may adhere to the following: 1) An application’s job request must be autonomous (that is, state does not need to be maintained between jobs), or graphics acceleration module 1546 must provide a context save and restore mechanism.2) An application’s job request is guaranteed by graphics acceleration module 1546 to complete in a specified amount of time, including any translation faults, or graphics acceleration module 1546 provides an ability to preempt processing of a job.3) Graphics acceleration module 1546 must be guaranteed fairness between processes when operating in a directed shared programming model. [0280] In at least one embodiment, application 1580 is required to make an operating system 1595 system call with a graphics acceleration module 1546 type, a work descriptor (WD), an authority mask register (AMR) value, and a context save/restore area pointer (CSRP). In at least one embodiment, graphics acceleration module 1546 type describes a targeted acceleration function for a system call. In at least one embodiment, graphics acceleration module 1546 type may be a system-specific value. In at least one embodiment, WD is formatted specifically for graphics acceleration module 1546 and can be in a form of a graphics acceleration module 1546 command, an effective address pointer to a user-defined structure, an effective address pointer to a queue of commands, or any other data structure to describe work to be done by graphics acceleration module 1546. In one embodiment, an AMR value is an AMR state to use for a current process. In at least one embodiment, a value passed to an operating system is similar to an application setting an AMR. If accelerator integration circuit 1536 and graphics acceleration module 1546 implementations do not support a User 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. Hypervisor 1596 may optionally apply a current Authority Mask Override Register (AMOR) value before placing an AMR into process element 1583. In at least one embodiment, CSRP is one of registers 1545 containing an effective address of an area in an application’s address space 1582 for graphics acceleration module 1546 to save and restore context state. This pointer is optional if no state is required to be saved between jobs or when a job is preempted. In at least one embodiment, context save/restore area may be pinned system memory. [0281] Upon receiving a system call, operating system 1595 may verify that application 1580 has registered and been given authority to use graphics acceleration module 1546. Operating system 1595 then calls hypervisor 1596 with information shown in Table 3. Table 3 –OS to Hypervisor Call Parameters
[0282] Upon receiving a hypervisor call, hypervisor 1596 verifies that operating system 1595 has registered and been given authority to use graphics acceleration module 1546. Hypervisor 1596 then puts process element 1583 into a process element linked list for a corresponding graphics acceleration module 1546 type. A process element may include information shown in Table 4. Table 4 –Process Element Information [0283] In at least one embodiment, hypervisor initializes a plurality of accelerator integration slice 1590 registers 1545. [0284] As illustrated in FIG.15F, in at least one embodiment, a unified memory is used, addressable via a common virtual memory address space used to access physical processor memories 1501-1502 and GPU memories 1520-1523. In this implementation, operations executed on GPUs 1510-1513 utilize a same virtual/effective memory address space to access processor memories 1501-1502 and vice versa, thereby simplifying programmability. In one embodiment, a first portion of a virtual/effective address space is allocated to processor memory 1501, a second portion to second processor memory 1502, a third portion to GPU memory 1520, and so on. In at least one embodiment, an entire virtual/effective memory space (sometimes referred to as an effective address space) is thereby distributed across each of processor memories 1501-1502 and GPU memories 1520-1523, allowing any processor or GPU to access any physical memory with a virtual address mapped to that memory. [0285] In one embodiment, bias/coherence management circuitry 1594A-1594E within one or more of MMUs 1539A-1539E ensures cache coherence between caches of one or more host processors (e.g., 1505) and GPUs 1510-1513 and implements biasing techniques indicating physical memories in which certain types of data should be stored. While multiple instances of bias/coherence management circuitry 1594A-1594E are illustrated in FIG.15F, bias/coherence circuitry may be implemented within an MMU of one or more host processors 1505 and/or within accelerator integration circuit 1536. [0286] One embodiment allows GPU-attached memory 1520-1523 to be mapped as part of system memory, and accessed using shared virtual memory (SVM) technology, but without suffering performance drawbacks associated with full system cache coherence. In at least one embodiment, an ability for GPU-attached memory 1520-1523 to be accessed as system memory without onerous cache coherence overhead provides a beneficial operating environment for GPU offload. This arrangement allows host processor 1505 software to setup operands and access computation results, without overhead of tradition I/O DMA data copies. Such traditional copies involve driver calls, interrupts and memory mapped I/O (MMIO) accesses that are all inefficient relative to simple memory accesses. In at least one embodiment, an ability to access GPU attached memory 1520-1523 without cache coherence overheads can be critical to execution time of an offloaded computation. In cases with substantial streaming write memory traffic, for example, cache coherence overhead can significantly reduce an effective write bandwidth seen by a GPU 1510-1513. In at least one embodiment, efficiency of operand setup, efficiency of results access, and efficiency of GPU computation may play a role in determining effectiveness of a GPU offload. [0287] In at least one embodiment, selection of GPU bias and host processor bias is driven by a bias tracker data structure. A bias table may be used, for example, which may be a page-granular structure (i.e., controlled at a granularity of a memory page) that includes 1 or 2 bits per GPU-attached memory page. In at least one embodiment, a bias table may be implemented in a stolen memory range of one or more GPU-attached memories 1520-1523, with or without a bias cache in GPU 1510-1513 (e.g., to cache frequently/recently used entries of a bias table). Alternatively, an entire bias table may be maintained within a GPU. [0288] In at least one embodiment, a bias table entry associated with each access to GPU-attached memory 1520-1523 is accessed prior to actual access to a GPU memory, causing the following operations. First, local requests from GPU 1510-1513 that find their page in GPU bias are forwarded directly to a corresponding GPU memory 1520-1523. Local requests from a GPU that find their page in host bias are forwarded to processor 1505 (e.g., over a high-speed link as discussed above). In one embodiment, requests from processor 1505 that find a requested page in host processor bias complete a request like a normal memory read. Alternatively, requests directed to a GPU-biased page may be forwarded to GPU 1510-1513. In at least one embodiment, a GPU may then transition a page to a host processor bias if it is not currently using a page. In at least one embodiment, bias state of a page can be changed either by a software-based mechanism, a hardware-assisted software-based mechanism, or, for a limited set of cases, a purely hardware-based mechanism. [0289] One mechanism for changing bias state employs an API call (e.g. OpenCL), which, in turn, calls a GPU’s device driver which, in turn, sends a message (or enqueues a command descriptor) to a GPU directing it to change a bias state and, for some transitions, perform a cache flushing operation in a host. In at least one embodiment, cache flushing operation is used for a transition from host processor 1505 bias to GPU bias, but is not for an opposite transition. [0290] In one embodiment, cache coherency is maintained by temporarily rendering GPU-biased pages uncacheable by host processor 1505. To access these pages, processor 1505 may request access from GPU 1510 which may or may not grant access right away. Thus, to reduce communication between processor 1505 and GPU 1510 it is beneficial to ensure that GPU-biased pages are those which are required by a GPU but not host processor 1505 and vice versa.

In at least one embodiment, each instance of neuron 2502 may include a neuron input 2504 and a neuron output 2506. In at least one embodiment, neurons 2502 may generate outputs that may be transmitted to inputs of other instances of neurons 2502. For example, in at least one embodiment, neuron inputs 2504 and neuron outputs 2506 may be interconnected via synapses 2508.

In at least one embodiment, neurons 2502 may sum or integrate signals received at neuron inputs 2504. For example, in at least one embodiment, neurons 2502 may be implemented as leaky integrate-and-fire neurons, wherein if a sum (referred to as a “membrane potential”) exceeds a threshold value, neuron 2502 may generate an output (or “fire”) using a transfer function such as a sigmoid or threshold function. In at least one embodiment, a leaky integrate-and-fire neuron may sum signals received at neuron inputs 2504 into a membrane potential and may also apply a decay factor (or leak) to reduce a membrane potential. In at least one embodiment, a leaky integrate-and-fire neuron may fire if multiple input signals are received at neuron inputs 2504 rapidly enough to exceed a threshold value (i.e., before a membrane potential decays too low to fire). In at least one embodiment, neurons 2502 may be implemented using circuits or logic that receive inputs, integrate inputs into a membrane potential, and decay a membrane potential. In at least one embodiment, inputs may be averaged, or any other suitable transfer function may be used.

In at least one embodiment, an instance of neuron 2502 generating an output to be transmitted over an instance of synapse 2508 may be referred to as a "pre-synaptic neuron” with respect to that instance of synapse 2508. In at least one embodiment, an instance of neuron 2502 receiving an input transmitted over an instance of synapse 2508 may be referred to as a “post-synaptic neuron” with respect to that instance of synapse 2508. Because an instance of neuron 2502 may receive inputs from one or more instances of synapse 2508, and may also transmit outputs over one or more instances of synapse 2508, a single instance of neuron 2502 may therefore be both a "pre-synaptic neuron” and “post-synaptic neuron,” with respect to various instances of synapses 2508, in at least one embodiment. [0382] In at least one embodiment, neurons 2502 may be organized into one or more layers. Each instance of neuron 2502 may have one neuron output 2506 that may fan out through one or more synapses 2508 to one or more neuron inputs 2504. In at least one embodiment, neuron outputs 2506 of neurons 2502 in a first layer 2510 may be connected to neuron inputs 2504 of neurons 2502 in a second layer 2512.

In at least one embodiment, first layer 2510 may be referred to as a “fully connected feed-forward layer.” In at least one embodiment, each instance of neuron 2502 in an instance of second layer 2512 may fan out to fewer than all instances of neuron 2502 in a third layer 2514. In at least one embodiment, second layer 2512 may be referred to as a “sparsely connected feed-forward layer.” In at least one embodiment, neurons 2502 in second layer 2512 may fan out to neurons 2502 in multiple other layers, including to neurons 2502 in (same) second layer 2512. In at least one embodiment, second layer 2512 may be referred to as a “recurrent layer.” neuromorphic processor 2500 may include, without limitation, any suitable combination of recurrent layers and feed-forward layers, including, without limitation, both sparsely connected feed-forward layers and fully connected feed-forward layers.

In at least one embodiment, neuromorphic processor 2500 may include, without limitation, circuitry or logic that allows synapses to be allocated to different neurons 2502 as needed based on neural network topology and neuron fan-in/out. For example, in at least one embodiment, synapses 2508 may be connected to neurons 2502 using an interconnect fabric, such as network-on-chip, or with dedicated connections.

In at least one embodiment, execution is multi-issue per clock to pipelines capable of integer, single and double precision floating point operations, SIMD branch capability, logical operations, transcendental operations, and other miscellaneous operations. In at least one embodiment, while waiting for data from memory or one of shared functions, dependency logic within execution units 3108A-3108N causes a waiting thread to sleep until requested data has been returned. In at least one embodiment, while a waiting thread is sleeping, hardware resources may be devoted to processing other threads. For example, in at least one embodiment, during a delay associated with a vertex shader operation, an execution unit can perform operations for a pixel shader, fragment shader, or another type of shader program, including a different vertex shader. [0438] In at least one embodiment, each execution unit in execution units 3108A-3108N operates on arrays of data elements. In at least one embodiment, a number of data elements is "execution size," or number of channels for an instruction. In at least one embodiment, an execution channel is a logical unit of execution for data element access, masking, and flow control within instructions. In at least one embodiment, a number of channels may be independent of a number of physical Arithmetic Logic Units (ALUs) or Floating Point Units (FPUs) for a particular graphics processor.

However, in at least one embodiment, different vector widths and register sizes are possible. [0440] In at least one embodiment, one or more execution units can be combined into a fused execution unit 3109A-3109N having thread control logic (3107A-3107N) that is common to fused EUs.

[0442] During execution, in at least one embodiment, graphics and media pipelines send thread initiation requests to thread execution logic 3100 via thread spawning and dispatch logic. In at least one embodiment, once a group of geometric objects has been processed and rasterized into pixel data, pixel processor logic (e.g., pixel shader logic, fragment shader logic, etc.) within shader processor 3102 is invoked to further compute output information and cause results to be written to output surfaces (e.g., color buffers, depth buffers, stencil buffers, etc.). In at least one embodiment, a pixel shader or fragment shader calculates values of various vertex attributes that are to be interpolated across a rasterized object. In at least one embodiment, pixel processor logic within shader processor 3102 then executes an application programming interface (API)-supplied pixel or fragment shader program.

[0500] Use of terms “a” and “an” and “the” and similar referents in context of describing disclosed embodiments (especially in context of following claims) are to be construed to cover both singular and plural, unless otherwise indicated herein or clearly contradicted by context, and not as a definition of a term. Terms “comprising,” “having,” “including,” and “containing” are to be construed as open-ended terms (meaning “including, but not limited to,”) unless otherwise noted. term “connected,” when unmodified and referring to physical connections, is to be construed as partly or wholly contained within, attached to, or joined together, even if there is something intervening. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within range, unless otherwise indicated herein and each separate value is incorporated into specification as if it were individually recited herein. use of term “set” (e.g., “a set of items”) or “subset” unless otherwise noted or contradicted by context, is to be construed as a nonempty collection comprising one or more members. Further, unless otherwise noted or contradicted by context, term “subset” of a corresponding set does not necessarily denote a proper subset of corresponding set, but subset and corresponding set may be equal. [0501] Conjunctive language, such as phrases of form “at least one of A, B, and C,” or “at least one of A, B and C,” unless specifically stated otherwise or otherwise clearly contradicted by context, is otherwise understood with context as used in general to present that an item, term, etc., may be either A or B or C, or any nonempty subset of set of A and B and C. For instance, in illustrative example of a set having three members, conjunctive phrases “at least one of A, B, and C” and “at least one of A, B and C” refer to any of following sets: {A}, {B}, {C}, {A, B}, {A, C}, {B, C}, {A, B, C}. Thus, such conjunctive language is not generally intended to imply that certain embodiments require at least one of A, at least one of B and at least one of C each to be present. In addition, unless otherwise noted or contradicted by context, term “plurality” indicates a state of being plural (e.g., “a plurality of items” indicates multiple items). number of items in a plurality is at least two, but can be more when so indicated either explicitly or by context. Further, unless stated otherwise or otherwise clear from context, phrase “based on” means “based at least in part on” and not “based solely on.” [0502] Operations of processes described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. In at least one embodiment, a process such as those processes described herein (or variations and/or combinations thereof) is performed under control of one or more computer systems configured with executable instructions and is implemented as code (e.g., executable instructions, one or more computer programs or one or more applications) executing collectively on one or more processors, by hardware or combinations thereof.

In at least one embodiment, code (e.g., executable code or source code) is stored on a set of one or more non-transitory computer-readable storage media having stored thereon executable instructions (or other memory to store executable instructions) that, when executed (i.e., as a result of being executed) by one or more processors of a computer system, cause computer system to perform operations described herein. set of non-transitory computer-readable storage media, in at least one embodiment, comprises multiple non-transitory computer-readable storage media and one or more of individual non-transitory storage media of multiple non-transitory computer-readable storage media lack all of code while multiple non-transitory computer-readable storage media collectively store all of code. In at least one embodiment, executable instructions are executed such that different instructions are executed by different processors — for example, a non-transitory computer-readable storage medium store instructions and a main central processing unit (“CPU”) executes some of instructions while a graphics processing unit (“GPU”) executes other instructions. In at least one embodiment, different components of a computer system have separate processors and different processors execute different subsets of instructions.

[0506] In description and claims, terms “coupled” and “connected,” along with their derivatives, may be used. It should be understood that these terms may be not intended as synonyms for each other. Rather, in particular examples, “connected” or “coupled” may be used to indicate that two or more elements are in direct or indirect physical or electrical contact with each other. “Coupled” may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other. [0507] Unless specifically stated otherwise, it may be appreciated that throughout specification terms such as “processing,” “computing,” “calculating,” “determining,” or like, refer to action and/or processes of a computer or computing system, or similar electronic computing device, that manipulate and/or transform data represented as physical, such as electronic, quantities within computing system’s registers and/or memories into other data similarly represented as physical quantities within computing system’s memories, registers or other such information storage, transmission or display devices. [0508] In a similar manner, term “processor” may refer to any device or portion of a device that processes electronic data from registers and/or memory and transform that electronic data into other electronic data that may be stored in registers and/or memory. As non-limiting examples, “processor” may be a CPU or a GPU. A “computing platform” may comprise one or more processors. As used herein, “software” processes may include, for example, software and/or hardware entities that perform work over time, such as tasks, threads, and intelligent agents.

In some implementations, process of obtaining, acquiring, receiving, or inputting analog or digital data can be accomplished by transferring data via a serial or parallel interface. In another implementation, process of obtaining, acquiring, receiving, or inputting analog or digital data can be accomplished by transferring data via a computer network from providing entity to acquiring entity. References may also be made to providing, outputting, transmitting, sending, or presenting analog or digital data. In various examples, process of providing, outputting, transmitting, sending, or presenting analog or digital data can be accomplished by transferring data as an input or output parameter of a function call, a parameter of an application programming interface or interprocess communication mechanism. [0510] Although discussion above sets forth example implementations of described techniques, other architectures may be used to implement described functionality, and are intended to be within scope of this disclosure. Furthermore, although specific distributions of responsibilities are defined above for purposes of discussion, various functions and responsibilities might be distributed and divided in different ways, depending on circumstances.
