[0227] In at least one embodiment, the LDW system provides visual, audible, and / or tactile warnings, such as steering wheel or seat vibrations, to alert the driver when the vehicle 1300 crosses a lane marking. In at least one embodiment, the LDW system is inactive when the driver indicates an intentional lane departure, such as by activating a turn signal.

[0229] In at least one embodiment, the RCTW system can provide visual, audible, and / or tactile notifications when an object is detected outside the rear camera range while the vehicle 1300 is in reverse. In at least one embodiment, the RCTW system includes an AEB system to ensure application of vehicle brakes to avoid a collision.

[0230] 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 because conventional ADAS systems alert the driver and allow the driver to decide whether a safe condition truly exists and take appropriate action. In at least one embodiment, in the event of conflicting results, the vehicle 1300 itself decides whether to follow the results of the primary or secondary computer (e.g., the first or second controller of controller 1336). For example, in at least one embodiment, the ADAS system 1338 can be a backup and / or auxiliary 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. In at least one embodiment, the output from the ADAS system 1338 can be provided to a supervisory MCU. In at least one embodiment, if the output from the primary and secondary computers conflict, the supervisory MCU determines how to reconcile the conflict to ensure safe operation.
[0231] In at least one embodiment, the primary computer can be configured to provide a confidence score to the supervisory MCU to indicate 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.
[0232] 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 secondary computer provides a false alarm based, at least in part, on output from the primary computer and output from the secondary computer. In at least one embodiment, the neural network in the supervisory MCU can learn when the output of the secondary computer can be trusted and when it cannot be trusted. For example, in at least one embodiment, when the secondary computer is a RADAR-based FCW system, the neural network in the supervisory MCU can learn when the FCW system identifies 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 secondary computer is a camera-based LDW system, the neural network in the supervisory MCU can learn to override the LDW when a cyclist or pedestrian is present and lane departure is actually the safest maneuver. In at least one embodiment, the supervisory MCU can include at least one of a DLA or a GPU suitable for running a neural network 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 1304.
[0233] In at least one embodiment, the ADAS system 1338 may include an auxiliary computer that uses traditional computer vision rules to perform ADAS functions. In at least one embodiment, the auxiliary computer may use classical computer vision rules (if-then), and the presence of a neural network 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 error in the software running on the main computer, and the different software code running on the auxiliary computer provides a consistent overall result, the supervisory MCU can be more confident that the overall result is correct and that the vulnerability in the software or hardware on the main computer will not cause a significant error.
[0234] In at least one embodiment, the output of the ADAS system 1338 can be input into the primary computer's perception module and / or the primary computer's dynamic driving task module. For example, in at least one embodiment, if the ADAS system 1338 indicates a forward collision warning due to an object directly ahead, the perception module can use this information when identifying the object. In at least one embodiment, as described herein, the secondary computer can have its own neural network that has been trained to reduce the risk of false positives.

In at least one embodiment, the infotainment SoC 1330 may be further configured to provide information (e.g., visual and / or auditory) to a user of the vehicle 1300, such as information from an ADAS system 1338, autonomous driving information (such as planned vehicle maneuvers), trajectory, surrounding environment information (e.g., intersection information, vehicle information, road information, etc.), and / or other information.
[0236] In at least one embodiment, the infotainment SoC 1330 can include any number and type of GPU functionality.

In at least one embodiment, the reasoning and / or training logic 1015 may be configured to perform the following operations on the system: Figure 17 In some embodiments, the present invention relates to a method for performing inference or prediction operations based at least in part on weight parameters, neural network functions and / or architectures computed using neural network training operations, or neural network use cases described herein.
[0274] In at least one embodiment, Figure 5 and Figure 7 The inference and / or training logic can be found in Figure 17 for use in a system for performing inference or prediction operations based at least in part on weight parameters computed using neural network training operations, neural network functions and / or architectures, or neural network use cases described herein.
[0275] Figure 18AAn exemplary architecture is shown in which a plurality of GPUs 1810(1)-1810(N) are communicatively coupled to a plurality of multi-core processors 1805(1)-1805(M) via high-speed links 1840(1)-1840(N) (e.g., a bus / point-to-point interconnect, etc.). In at least one embodiment, the high-speed links 1840(1)-1840(N) support 4 GB / s, 30 GB / s, 80 GB / s, or higher communication throughput. In at least one embodiment, various interconnect protocols may be used, including, but not limited to, PCIe 4.0 or 5.0 and NVLink 2.0. In the various figures, "N" and "M" represent positive integers, the values of which may vary from figure to figure.
[0276] Furthermore, in one embodiment, two or more GPUs 1810 are interconnected via high-speed links 1829(1)-1829(2), which may be implemented using protocols / links similar to or different from those used for high-speed links 1840(1)-1840(N). Similarly, two or more multi-core processors 1805 may be connected via high-speed link 1828, 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 18A All communications between the various system components shown in .
[0277] In one embodiment, each multi-core processor 1805 is communicatively coupled to processor memory 1801(1)-1801(M) via memory interconnects 1826(1)-1826(M), respectively, and each GPU 1810(1)-1810(N) is communicatively coupled to GPU memory 1820(1)-1820(N) via GPU memory interconnects 1850(1)-1850(N), respectively. In at least one embodiment, memory interconnects 1826 and 1850 can utilize similar or different memory access technologies. By way of example and not limitation, processor memory 1801(1)-1801(M) and GPU memory 1820 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 1801 may be volatile memory, while another portion may be non-volatile memory (eg, using a two-level memory (2LM) hierarchy).
[0278] As described herein, although the various multi-core processors 1805 and GPUs 1810 may be physically coupled to specific memories 1801, 1820, respectively, and / or a unified memory architecture may 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 1801(1)-1801(M) may each contain 64GB of system memory address space, and GPU memories 1820(1)-1820(N) may each contain 32GB of system memory address space, resulting in a total addressable memory size of 256GB when M=2 and N=4. Other values of N and M are also possible.
[0279] Figure 18B Additional details are shown for the interconnection between the multi-core processor 1807 and the graphics acceleration module 1846 according to an exemplary embodiment. In at least one embodiment, the graphics acceleration module 1846 may include one or more GPU chips integrated on a line card that is coupled to the processor 1807 via a high-speed link 1840 (e.g., a PCIe bus, NVLink, etc.). In at least one embodiment, the graphics acceleration module 1846 may be selectively integrated on a package or chip with the processor 1807.
[0280] In at least one embodiment, processor 1807 includes multiple cores 1860A-1860D, each core having a translation lookaside buffer ("TLB") 1861A-1861D and one or more caches 1862A-1862D. In at least one embodiment, cores 1860A-1860D may include various other components, not shown, for executing instructions and processing data. In at least one embodiment, caches 1862A-1862D may include level 1 (L1) and level 2 (L2) caches. In addition, one or more shared caches 1856 may be included in caches 1862A-1862D and shared by each group of cores 1860A-1860D. For example, one embodiment of processor 1807 includes 24 cores, each core having its own L1 cache, twelve shared L2 caches, and twelve shared L3 caches. In this embodiment, two adjacent cores share one or more L2 and L3 caches. In at least one embodiment, the processor 1807 and the graphics acceleration module 1846 are connected to the system memory 1814, which may include Figure 18A Processor memory 1801(1)-1801(M) in.
[0281] In at least one embodiment, coherency is maintained for data and instructions stored in the various caches 1862A-1862D, 1856, and system memory 1814 via inter-core communication over a coherency bus 1864. In at least one embodiment, for example, each cache may have cache coherency logic / circuitry associated therewith to communicate over the coherency bus 1864 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 1864 to snoop cache accesses.
[0282] In at least one embodiment, proxy circuitry 1825 communicatively couples graphics acceleration module 1846 to coherence bus 1864, thereby allowing graphics acceleration module 1846 to participate in a cache coherence protocol as a peer of cores 1860A-1860D. In particular, in at least one embodiment, interface 1835 provides connectivity to proxy circuitry 1825 via high-speed link 1840, and interface 1837 connects graphics acceleration module 1846 to high-speed link 1840.
[0283] In at least one embodiment, the accelerator integrated circuit 1836 provides cache management, memory access, context management, and interrupt management services on behalf of the multiple graphics processing engines 1831(1)-1831(N) of the graphics acceleration module. In at least one embodiment, the graphics processing engines 1831(1)-1831(N) may each include a separate graphics processing unit (GPU). In at least one embodiment, the graphics processing engines 1831(1)-1831(N) may optionally include different types of graphics processing engines within the GPU, such as 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 1846 may be a GPU having multiple graphics processing engines 1831(1)-1831(N), or the graphics processing engines 1831(1)-1831(N) may be individual GPUs integrated on a common package, line card, or chip.
[0284] In at least one embodiment, the accelerator integrated circuit 1836 includes a memory management unit (MMU) 1839 for performing various memory management functions, such as virtual to physical memory translation (also known as effective to real memory translation), and a memory access protocol for accessing system memory 1814. In at least one embodiment, the MMU 1839 may also include a translation lookaside buffer ("TLB") (not shown) for caching virtual / effective to physical / real address translations. In at least one embodiment, a cache 1838 may store commands and data for efficient access by the graphics processing engines 1831(1)-1831(N). In at least one embodiment, a fetch unit 1844 may be used to keep data stored in the cache 1838 and graphics memory 1833(1)-1833(M) consistent with the core caches 1862A-1862D, 1856, and system memory 1814. As previously described, this task may be accomplished via proxy circuitry 1825 acting on behalf of cache 1838 and graphics memory 1833(1)-1833(M) (e.g., sending updates relating to modifications / accesses of cache lines on processor caches 1862A-1862D, 1856 to cache 1838 and receiving updates from cache 1838).
[0285] In at least one embodiment, a set of registers 1845 stores context data for threads executed by graphics processing engines 1831(1)-1831(N), and context management circuitry 1848 manages thread contexts. For example, context management circuitry 1848 can perform save and restore operations to save and restore the contexts of 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 1848 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 context. In at least one embodiment, interrupt management circuitry 1847 receives and processes interrupts received from system devices.
[0286] In one implementation, the MMU 1839 translates virtual / effective addresses from the graphics processing engine 1831 into real / physical addresses in the system memory 1814. In at least one embodiment, the accelerator integrated circuit 1836 supports multiple (e.g., 4, 8, 16) graphics accelerator modules 1846 and / or other accelerator devices. In at least one embodiment, the graphics accelerator module 1846 can be dedicated to a single application executing on the processor 1807, 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 1831 (1)-1831 (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.
[0287] In at least one embodiment, the accelerator integrated circuit 1836 acts as a bridge to the system for the graphics acceleration module 1846 and provides address translation and system memory caching services. Additionally, in at least one embodiment, the accelerator integrated circuit 1836 can provide virtualization facilities for the host processor to manage virtualization, interrupts, and memory management for the graphics processing engines 1831(1)-1831(N).
[0288] In at least one embodiment, because the hardware resources of graphics processing engines 1831(1)-1831(N) are explicitly mapped into the real address space seen by host processor 1807, any host processor can directly address these resources using effective address values. In at least one embodiment, one function of accelerator integrated circuit 1836 is to physically separate graphics processing engines 1831(1)-1831(N) so that they appear to the system as independent units.
[0289] In at least one embodiment, one or more graphics memories 1833(1)-1833(M) are coupled to each graphics processing engine 1831(1)-1831(N), respectively, and N=M. In at least one embodiment, graphics memories 1833(1)-1833(M) store instructions and data that are processed by each graphics processing engine 1831(1)-1831(N). In at least one embodiment, graphics memories 1833(1)-1833(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.
[0290] In one embodiment, to reduce data traffic on high-speed link 1840, a biasing technique is used to ensure that the data stored in graphics memory 1833(1)-1833(M) is the data most frequently used by graphics processing engines 1831(1)-1831(N), and preferably the data not used (at least not frequently) by cores 1860A-1860D. Similarly, in at least one embodiment, the biasing mechanism attempts to keep data needed by the cores (and preferably not graphics processing engines 1831(-1)-1831(N)) in caches 1862A-1862D, 1856, and system memory 1814.
[0291] Figure 18C Another exemplary embodiment is shown in which an accelerator integrated circuit 1836 is integrated within the processor 1807. In this embodiment, the graphics processing engines 1831(1)-1831(N) communicate directly with the accelerator integrated circuit 1836 via interface 1837 and interface 1835 (which may also be any form of bus or interface protocol) over a high-speed link 1840. In at least one embodiment, the accelerator integrated circuit 1836 may perform operations related to the graphics processing engine 1831(1)-1831(N). Figure 18B The operations described above are similar to those described above. However, due to its close proximity to the coherence bus 1864 and caches 1862A-1862D, 1856, higher throughput is possible. One embodiment supports different programming models, including a dedicated process programming model (without graphics acceleration module virtualization) and a shared programming model (with virtualization), which can include a programming model controlled by the accelerator integrated circuit 1836 and a programming model controlled by the graphics acceleration module 1846.
[0292] In at least one embodiment, graphics processing engines 1831(1)-1831(N) are dedicated to a single application or process under a single operating system. In at least one embodiment, a single application can funnel other application requests to graphics processing engines 1831(1)-1831(N), thereby providing virtualization within a VM / partition.
[0293] In at least one embodiment, graphics processing engines 1831(1)-1831(N) can be shared by multiple VM / application partitions. In at least one embodiment, the sharing model can use a hypervisor to virtualize graphics processing engines 1831(1)-1831(N) to allow each operating system to access them. In at least one embodiment, for a single partition system without a hypervisor, the operating system owns graphics processing engines 1831(1)-1831(N). In at least one embodiment, the operating system can virtualize graphics processing engines 1831(1)-1831(N) to provide access to each process or application.
[0294] In at least one embodiment, the graphics acceleration module 1846 or individual graphics processing engines 1831(1)-1831(N) use a process handle to select a process element. In at least one embodiment, the process element is stored in system memory 1814 and can be addressed using the effective address to real address translation techniques described herein. In at least one embodiment, the process handle can be an implementation-specific value that is provided to the host process when registering its context with the graphics processing engine 1831(1)-1831(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.
[0295] Figure 18D An exemplary accelerator integrated slice 1890 is shown. In at least one embodiment, a "slice" comprises a designated portion of the processing resources of the accelerator integrated circuit 1836. In at least one embodiment, the application is an effective address space 1882 in system memory 1814, which stores a process element 1883. In at least one embodiment, the process element 1883 is stored in response to a GPU call 1881 from an application 1880 executing on the processor 1807. In at least one embodiment, the process element 1883 contains the process state of the corresponding application 1880. In one embodiment, the work descriptor (WD) 1884 contained in the process element 1883 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 1884 is a pointer to a job request queue in the effective address space 1882 of the application.
[0296] In at least one embodiment, the graphics acceleration module 1846 and / or the individual graphics processing engines 1831(1)-1831(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 1884 to the graphics acceleration module 1846 to start a job in a virtualized environment.
[0297] In at least one embodiment, the dedicated process programming model is implementation specific. In at least one embodiment, in this model, a single process owns either a graphics acceleration module 1846 or an individual graphics processing engine 1831. In at least one embodiment, when a graphics acceleration module 1846 is owned by a single process, the hypervisor initializes the accelerator integrated circuit for the owned partition, and when a graphics acceleration module 1846 is assigned, the operating system initializes the accelerator integrated circuit 1836 for the owned process.
[0298] In at least one embodiment, in operation, a WD fetch unit 1891 in the accelerator integrated slice 1890 fetches the next WD 1884, which includes an indication of work to be performed by one or more graphics processing engines of the graphics acceleration module 1846. In at least one embodiment, data from the WD 1884 can be stored in registers 1845 and used by the MMU 1839, interrupt management circuitry 1847, and / or context management circuitry 1848, as shown. For example, one embodiment of the MMU 1839 includes segment / page roaming circuitry for accessing segment / page tables 1886 within the OS virtual address space 1885. In at least one embodiment, the interrupt management circuitry 1847 can process interrupt events 1892 received from the graphics acceleration module 1846. In at least one embodiment, when performing graphics operations, effective addresses 1893 generated by the graphics processing engines 1831(1)-1831(N) are converted to real addresses by the MMU 1839.
[0299] In one embodiment, registers 1845 are replicated for each graphics processing engine 1831(1)-1831(N) and / or graphics acceleration module 1846, and the registers 1845 can be initialized by the hypervisor or operating system. In at least one embodiment, each of these replicated registers can be included in the accelerator integration slice 1890. Exemplary registers that can be initialized by the hypervisor are shown in Table 1.
[0300]
[0301]
[0302] Example registers that may be initialized by the operating system are shown in Table 2.
[0303]
[0304] In at least one embodiment, each WD 1884 is specific to a particular graphics acceleration module 1846 and / or graphics processing engine 1831(1)-1831(N). In at least one embodiment, it contains all the information needed by the graphics processing engine 1831(1)-1831(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.

[0306] In at least one embodiment, the shared programming model allows all processes or a subset of processes from all partitions or a subset of partitions in the system to use the graphics acceleration module 1846. In at least one embodiment, there are two programming models in which the graphics acceleration module 1846 is shared by multiple processes and partitions, namely, time-sliced sharing and graphics-directed sharing.
[0307] In at least one embodiment, in this model, the hypervisor 1896 owns the graphics acceleration module 1846 and makes its functionality available to all operating systems 1895. In at least one embodiment, for the graphics acceleration module 1846 to support virtualization through the hypervisor 1896, the graphics acceleration module 1846 may 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 1846 must provide a context save and restore mechanism, (2) the graphics acceleration module 1846 guarantees that the application's job requests are completed within a specified amount of time, including any transition errors, or the graphics acceleration module 1846 provides the ability to preempt job processing, and (3) fairness between graphics acceleration module 1846 processes must be ensured when operating in a directed shared programming model.
[0308] In at least one embodiment, the application 1880 is required to make an operating system 1895 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 function for the system call. In at least one embodiment, the graphics acceleration module type can be a system-specific value. In at least one embodiment, the WD is formatted specifically for the graphics acceleration module 1846 and can take the form of a graphics acceleration module 1846 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 1846.
[0309] 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 1836 (not shown) and the graphics acceleration module 1846 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 1896 may selectively apply the current AMR value before placing the AMR into the process element 1883. In at least one embodiment, the CSRP is one of the registers 1845 that contains the effective address of an area in the application's effective address space 1882 for the graphics acceleration module 1846 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.
[0310] Upon receiving the system call, the operating system 1895 can verify that the application 1880 has been registered and granted permission to use the graphics acceleration module 1846. Then, in at least one embodiment, the operating system 1895 calls the hypervisor 1896 using the information shown in Table 3.
[0311]
[0312] In at least one embodiment, upon receiving the hypervisor call, hypervisor 1896 verifies that operating system 1895 has registered and been granted permission to use graphics acceleration module 1846. Then, in at least one embodiment, hypervisor 1896 places process element 1883 into a linked list of process elements of the corresponding graphics acceleration module 1846 type. In at least one embodiment, the process element may include the information shown in Table 4.
[0313]
[0314]
[0315] In at least one embodiment, the hypervisor initializes the plurality of accelerator integrated slice 1890 registers 1845 .
[0316] like Figure 18FAs 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 1801(1)-1801(N) and GPU memory 1820(1)-1820(N). In this implementation, operations executed on GPUs 1810(1)-1810(N) utilize the same virtual / effective memory address space to access processor memory 1801(1)-1801(M), and vice versa, thereby simplifying programmability. In at least one embodiment, a first portion of the virtual / effective address space is allocated to processor memory 1801(1), a second portion is allocated to second processor memory 1801(N), a third portion is allocated to GPU memory 1820(1), and so on. In at least one embodiment, the entire virtual / effective memory space (sometimes referred to as the effective address space) is thus distributed across each of processor memory 1801 and GPU memory 1820, thereby allowing any processor or GPU to access that memory using a virtual address that maps to any physical memory.
[0317] In one embodiment, bias / coherency management circuitry 1894A-1894E within one or more MMUs 1839A-1839E ensures cache coherency between the caches of one or more host processors (e.g., 1805) and GPU 1810 and implements biasing techniques that indicate physical memory where certain types of data should be stored. In at least one embodiment, while Figure 18F Multiple instances of bias / coherence management circuits 1894A- 1894E are shown in , but bias / coherence circuits may be implemented within an MMU of one or more host processors 1805 and / or within an accelerator integrated circuit 1836 .
[0318] One embodiment allows GPU memory 1820 to be mapped as part of system memory and accessed using shared virtual memory (SVM) technology, without suffering the performance drawbacks associated with full system cache coherence. In at least one embodiment, the ability to access GPU memory 1820 as system memory without the heavy cache coherence overhead provides a favorable operating environment for GPU offloading. In at least one embodiment, this arrangement allows host processor 1805 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 include driver calls, interrupts, and memory-mapped I / O (MMIO) accesses, all of which are less efficient than simple memory accesses. In at least one embodiment, the ability to access GPU memory 1820 without cache coherence overhead 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 1810. 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.
[0319] 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 of memory per GPU-attached page. In at least one embodiment, the bias table can be implemented in a stolen memory range of one or more GPU memories 1820, with or without a bias cache in GPU 1810 (e.g., to cache frequently / recently used entries of the bias table). Alternatively, in at least one embodiment, the entire bias table can be maintained within the GPU.
[0320] In at least one embodiment, the bias table entry associated with each access to GPU-attached memory 1820 is accessed before the GPU memory is actually accessed, resulting in the following operations. In at least one embodiment, local requests from GPU 1810 whose pages are found in the GPU bias are forwarded directly to the corresponding GPU memory 1820. In at least one embodiment, local requests from the GPU whose pages are found in the host bias are forwarded to processor 1805 (e.g., via the high-speed link described herein). In at least one embodiment, requests from processor 1805 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 1810. In at least one embodiment, if the GPU is not currently using the page, the GPU can subsequently 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 limited cases, a purely hardware-based mechanism.
[0321] In at least one embodiment, a mechanism for changing the bias state employs an API call (e.g., OpenCL) that in turn calls the GPU's device driver, 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 1805 bias to GPU bias, but not for the reverse migration.
[0322] In one embodiment, cache coherence is maintained by temporarily rendering GPU-biased pages that cannot be cached by host processor 1805. In at least one embodiment, to access these pages, processor 1805 may request access from GPU 1810, which may or may not immediately grant access. Therefore, in at least one embodiment, to reduce communication between processor 1805 and GPU 1810, it is beneficial to ensure that GPU-biased pages are the pages required by the GPU and not the host processor 1805, and vice versa.

In at least one embodiment, the neurons 2802 and their components can be implemented using circuitry or logic including one or more arithmetic logic units (ALUs). In at least one embodiment, the neuromorphic processor 2800 can include, but is not limited to, thousands of instances of neurons 2802, although any suitable number of neurons 2802 can be used. In at least one embodiment, each instance of a neuron 2802 can include a neuron input 2804 and a neuron output 2806. In at least one embodiment, a neuron 2802 can generate an output that can be transmitted to the inputs of other instances of the neuron 2802. In at least one embodiment, the neuron input 2804 and the neuron output 2806 can be interconnected via a synapse 2808.

For example, in at least one embodiment, the neuron 2802 can be implemented as a leaky integrate-and-trigger neuron, where if the sum (referred to as the "membrane potential") exceeds a threshold, the neuron 2802 can generate an output (or "trigger") using a transfer function such as a sigmoid or threshold function. In at least one embodiment, the leaky integrate-and-trigger neuron can sum the signal received at the neuron input 2804 into a membrane potential and can apply an application attenuation factor (or leakage) to reduce the membrane potential. In at least one embodiment, a leaky integrate-and-fire neuron may trigger if multiple input signals are received at neuron input 2804 quickly enough to exceed a threshold (i.e., before the membrane potential decays too low to trigger). In at least one embodiment, neuron 2802 may be implemented using circuitry or logic that receives input, integrates the input into a membrane potential, and decays the membrane potential. In at least one embodiment, the inputs may be averaged, or any other suitable transfer function may be used.

In at least one embodiment, one or more instances of a neuron output 2806 can be connected to an instance of a neuron input 2804 in the same neuron 2802 via an instance of synapse 2808. In at least one embodiment, an instance of a neuron 2802 that generates an output to be transmitted across an instance of synapse 2808 can be referred to as a "presynaptic neuron" relative to that instance of synapse 2808. In at least one embodiment, an instance of a neuron 2802 that receives an input transmitted across an instance of synapse 2808 can be referred to as a "postsynaptic neuron" relative to an instance of synapse 2808. In at least one embodiment, with respect to the various instances of synapses 2808, because an instance of neuron 2802 can receive input from one or more instances of synapses 2808 and can also transmit output through one or more instances of synapses 2808, a single instance of neuron 2802 can be both a "pre-synaptic neuron" and a "post-synaptic neuron."
[0415] In at least one embodiment, neurons 2802 may be organized into one or more layers. In at least one embodiment, each instance of a neuron 2802 may have a neuron output 2806 that may fan out to one or more neuron inputs 2804 via one or more synapses 2808.

In at least one embodiment, layers 2810 may be referred to as "feed-forward layers." In at least one embodiment, each instance of a neuron 2802 in an instance of the first layer 2810 may fan out to each instance of a neuron 2802 in the second layer 2812. In at least one embodiment, the first layer 2810 may be referred to as a "fully connected feed-forward layer." In at least one embodiment, each instance of a neuron 2802 in each instance of the second layer 2812 may fan out to fewer than all instances of a neuron 2802 in the third layer 2814.
