In at least one embodiment, the RCTW system can use one or more rear-facing radar sensors coupled to a dedicated processor, DSP, FPGA, and / or ASIC, which is electrically coupled to provide feedback to the driver, such as a display, a speaker, and / or a vibrating component.
[0175] In at least one embodiment, conventional ADAS systems can be prone to false positives, which can be annoying and distracting for the driver, but are typically not catastrophic because conventional ADAS systems warn the driver and give them the opportunity to decide whether a safety condition actually exists and to act accordingly. In at least one embodiment, the vehicle 1200 itself decides, in the event of conflicting results, whether to follow the result of a primary computer or a secondary computer (e.g., a first controller 1236 or a second controller of the controllers 1236). In at least one embodiment, the ADAS system 1238 can, for example, be a backup and / or secondary computer that provides perceptual information to a rationality module of the backup computer.In at least one embodiment, a rationality monitor of the backup computer can execute redundant, diverse software on hardware components to detect errors in perception and dynamic driving tasks.

[0176] In at least one embodiment, a primary computer can be configured to provide the higher-level MCU with a confidence value indicating the primary computer's confidence in the selected result. In at least one embodiment, the supervising MCU can follow the primary computer's instruction if the confidence value exceeds a threshold, regardless of whether the secondary computer delivers a contradictory or inconsistent result. In at least one embodiment where the confidence value does not reach the threshold and the primary and secondary computers display different results (e.g., a conflict), the supervising MCU can mediate between the computers to determine the appropriate result.
[0177] In at least one embodiment, the monitoring MCU can be configured to execute a neural network or networks that are trained and configured to determine, at least partially, based on outputs from a primary computer and outputs from a secondary computer, the conditions under which the secondary computer triggers false alarms. In at least one embodiment, the neural network(s) in the monitoring MCU can learn when the output of the secondary computer can be trusted and when it cannot. For example, in at least one embodiment, if the secondary computer is a radar-based FCW system, a neural network in the monitoring MCU can learn when the FCW system identifies metallic objects that are not actually hazards, such as a drain grate or a manhole cover, triggering an alarm.In at least one embodiment, where the secondary computer is a camera-based LDW system, a neural network in the monitoring MCU can learn to override the LDW system when cyclists or pedestrians are present and leaving the lane is indeed the safest maneuver.

In at least one embodiment, the monitoring MCU can include and / or be contained within a component of the SoC(s) 1204.
[0178] In at least one embodiment, the ADAS system 1238 can include a secondary computer that executes the ADAS functionality using conventional computer vision rules. In at least one embodiment, the secondary computer can use classic computer vision rules (if-then), and the presence of a neural network (or neural networks) in the higher-level MCU can improve reliability, safety, and performance. In at least one embodiment, the overall system becomes more fault-tolerant due to the different implementation and intentional non-identity, particularly with respect to errors caused by software functions (or software-hardware interfaces).For example, in at least one embodiment, if there is a software bug or error in the software running on the primary computer, and if non-identical software code running on the secondary computer produces a consistent overall result, then the monitoring MCU can have greater confidence that an overall result is correct and that a bug in the software or hardware on the primary computer is not causing a material error.
[0179] In at least one embodiment, an output from the ADAS system 1238 can be fed into the perception block and / or the dynamic driving task block of the primary computer. For example, if, in at least one embodiment, the ADAS system 1238 displays a forward crash warning due to an object immediately ahead, the perception block can use this information in object identification. In at least one embodiment, the secondary computer can have its own trained neural network, thus reducing the risk of false alarms, as described herein.

In at least one embodiment, the graphics acceleration module 1746 can comprise one or more GPU chips integrated on a line card connected to the processor 1707 via a high-speed connection 1740 (e.g., a PCIe bus, NVLink, etc.). Alternatively, in at least one embodiment, the graphics acceleration module 1746 can be integrated on a package or chip with the processor 1707.
[0224] In at least one embodiment, the processor 1707 comprises a plurality of cores 1760A-1760D (which may be referred to as "execution units"), each with a translation lookaside buffer ("TLB") 1761A-1761D and one or more caches 1762A-1762D.

In at least one embodiment, the caches 1762A-1762D may include Level 1 (L1) and Level 2 (L2) caches. Additionally, one or more shared caches 1756 may be present within the caches 1762A-1762D, which are shared by groups of cores 1760A-1760D. For example, one embodiment of the 1707 processor has 24 cores, each with its own L1 cache, twelve shared L2 caches and twelve shared L3 caches.In this embodiment, one or more L2 and L3 caches are shared by two adjacent cores. In at least one embodiment, the processor 1707 and the graphics acceleration module 1746 are connected to the system memory 1714, which shares the processor memories 1701(1) - 1701(M) of . Fig. can exhibit 17A.
[0225] In at least one embodiment, the coherence of data and instructions stored in various caches 1762A-1762D, 1756, and system memory 1714 is maintained by communication between the cores via a coherence bus 1764. In at least one embodiment, for example, each cache can have cache coherence logic / circuitry connected to it to communicate via the coherence bus 1764 in response to detected read or write operations in specific cache rows. In at least one embodiment, a cache snooping protocol is implemented over the coherence bus 1764 to monitor cache accesses.
[0226] In at least one embodiment, a proxy circuit 1725 communicatively couples the graphics acceleration module 1746 to the coherence bus 1764, so that the graphics acceleration module 1746 can participate in a cache coherence protocol as a peer of the cores 1760A-1760D. In at least one embodiment, an interface 1735 provides connectivity with the proxy circuit 1725 via the high-speed connection 1740, and an interface 1737 connects the graphics acceleration module 1746 to the high-speed connection 1740.
[0227] In at least one embodiment, an accelerator integration circuit 1736 provides cache management, memory access, context management, and interrupt management services on behalf of a plurality of graphics processing machines 1731(1) to 1731(N) of the graphics acceleration module 1746. In at least one embodiment, the graphics processing machines 1731(1) to 1731(N) can each comprise a separate graphics processing unit (GPU). In at least one embodiment, the plurality of graphics processing machines 1731(1) to 1731(N) of the graphics acceleration module 1746 can comprise one or more graphics cores 2000, as described in the following sections: Fig. 20A and Fig.20B is discussed. In at least one embodiment, the graphics processing machines 1731(1) - 1731(N) can alternatively comprise different types of graphics processing machines within a graphics processor, such as graphics execution units, media processing machines (e.g., video encoders / decoders), samplers, and blith modules. In at least one embodiment, the graphics acceleration module 1746 can be a GPU with a plurality of graphics processing units 1731(1) - 1731(N), or the graphics processing units 1731(1) - 1731(N) can be individual GPUs integrated in a common package, line card, or chip.
[0228] In one embodiment, the accelerator integration circuit 1736 includes a memory management unit (MMU) 1739 to perform various memory management functions, such as translations from virtual to physical memory (also referred to as translations from effective to real memory) and memory access protocols for accessing the system memory 1714. In at least one embodiment, the MMU 1739 may also include a translation lookaside buffer (TLB) (not shown) to cache translations from virtual / effective to physical / real addresses. In at least one embodiment, instructions and data may be stored in a cache 1738 for efficient access by the graphics processors 1731(1) - 1731(N).In at least one embodiment, the data stored in the cache 1738 and in the graphics memories 1733(1) - 1733(M) are kept coherent with the core caches 1762A-1762D, 1756 and the system memory 1714, possibly employing a retrieval unit 1744. As already mentioned, this can be accomplished via a proxy circuit 1725 on behalf of the cache 1738 and the memories 1733(1) - 1733(M) (e.g., sending updates to the cache 1738 in connection with changes / accesses to cache lines in the processor caches 1762A-1762D, 1756 and receiving updates from the cache 1738).
[0229] In at least one embodiment, a set of registers 1745 stores context data for threads executed by graphics processing machines 1731(1) - 1731N, and a context management circuit 1748 manages thread contexts. For example, the context management circuit 1748 can perform save and restore operations to save and restore the contexts of different threads during context switching (e.g., when a first thread is saved and a second thread is saved so that a second thread can be executed by a graphics processing machine). During a context switch, the context management circuit 1748 can, for example, store current register values in a specific area in memory (e.g., identified by a context pointer). The register values can then be restored upon returning to a context.In at least one embodiment, an interrupt management circuit 1747 receives and processes interruptions received by system devices.
[0230] In at least one embodiment, virtual / effective addresses from a graphics processing unit 1731 are translated by the MMU 1739 into real / physical addresses in system memory 1714.

Furthermore, in at least one embodiment, the accelerator integration circuit 1736 can provide virtualization functions for a host processor to manage the virtualization of the graphics processing modules 1731(1) - 1731(N), interrupts, and memory management.
[0232] Since, in at least one embodiment, the hardware resources of the graphics processors 1731(1) - 1731(N) are explicitly mapped to a real address space seen by the host processor 1707, each host processor can directly address these resources with an effective address value. In at least one embodiment, a function of the accelerator integration circuit 1736 is the physical separation of the graphics processing machines 1731(1) - 1731(N), so that they appear to a system as independent units.

[0234] In at least one embodiment, allocation or biasing methods can be used to reduce data traffic over the high-speed connection 1740 by ensuring that the data stored in the graphics memories 1733(1) - 1733(M) is data most frequently used by the graphics processing units 1731(1) - 1731(N) and preferably not (or at least not frequently) used by the cores 1760A-1760D. Similarly, in at least one embodiment, an allocation or biasing mechanism attempts to keep data required by cores (and preferably not by the graphics processing units 1731(1) - 1731(N)) in the caches 1762A-1762D, 1756, and in system memory 1714.

[0241] Fig.Figure 17D shows an exemplary accelerator integration slice 1790. In at least one embodiment, a "slice" comprises a specific portion of the processing resources of the accelerator integration circuit 1736.

In at least one embodiment, a process element 1783 contains the process state for the corresponding application 1780. In at least one embodiment, a work descriptor (WD) 1784 contained in the process element 1783 can be a single job requested by an application or a pointer to a queue of jobs.In at least one embodiment, the WD 1784 is a pointer to a job request queue in the effective address space 1782 of an application.

[0243] In at least one embodiment, a programming model for dedicated processes is implementation-specific. In at least one embodiment, a single process in this model owns the graphics acceleration module 1746 or a single graphics processing machine 1731. When the graphics acceleration module 1746 is owned by a single process in at least one embodiment, a hypervisor initializes the accelerator integration circuit 1736 for an owning partition, and an operating system initializes the accelerator integration circuit 1736 for an owning process when the graphics acceleration module 1746 is allocated.
[0244] In operation, a WD retrieval unit 1791 in the accelerator integration slice 1790 retrieves the nearest WD 1784 in at least one embodiment. This WD contains information about the work to be performed by one or more graphics processing units of the graphics acceleration module 1746. In at least one embodiment, the data from the WD 1784 can be stored in registers 1745 and used by the MMU 1739, the interrupt management circuit 1747, and / or the context management circuit 1748, as shown. For example, one embodiment of the MMU 1739 includes a segment / page scrolling circuit for accessing segment / page tables 1786 in the virtual address space 1785 of the operating system. In at least one embodiment, the interrupt management circuit 1747 can process interrupt events 1792 received from the graphics acceleration module 1746.In at least one embodiment, when performing graphics operations, an effective address 1793, generated by a graphics processing machine 1731-1731, N, is translated into a real address by the MMU 1739.
[0245] In at least one embodiment, for each graphics processing machine 1731(1) - 1731(N) and / or each graphics acceleration module 1746, the same set of registers 1745 is duplicated and can be initialized by a hypervisor or operating system.

[0247] In at least one embodiment, each WD 1784 is specific to a particular graphics acceleration module 1746 and / or the graphics processing machines 1731(1) - 1731(N). In at least one embodiment, it contains all the information required by a graphics processing machine 1731(1) - 1731(N) to perform work, or it can be a pointer to a memory location where an application has established a queue of commands to be executed.
[0248] In at least one embodiment, at least one in Fig. The component shown or described in Figure 17D is used to implement procedures and / or functions related to the Fig. 1-8 are described. In at least one embodiment, at least one component of Fig.17D is used to cause access to a three-dimensional (3D) representation of an environment, the determination of one or more static features and one or more dynamic features of the 3D representation, the determination of one or more static density values, the determination of one or more dynamic density values, and / or the generation of one or more images based on the one or more static density values and the one or more dynamic density values. In at least one embodiment, at least one component of Fig. 17D selects at least one aspect relating to the machine learning model(s) 110, the static hash encoder 104, the dynamic hash encoder 106, the flow hash encoder 108, the RGB mesh 130, the rendering module 120, the gaze direction module 112 and / or the processor 140 of Fig. 1, the scene breakdown 200 of Fig.2, the image generation 300 of Fig. 3, the hash encoder 404, the hash encoder 424, the MLP 408, the MLP 428, the static RGB net 414, the dynamic RGB net 434 and / or the renderer 420 of Fig. 4, the hash encoder 504, the hash encoder 524, the MLP 508, the MLP 528, the RGB net 534 and / or the renderer 520 of Fig. 5, the static and dynamic decomposition 600 of Fig. 6, the procedure 700 of Fig. 7 and / or the 800 processor from Fig. 8 is described.
[0249] Fig.Figure 17E illustrates additional details for an exemplary embodiment of a common model. This embodiment has a real hypervisor address space 1798 in which a process element list 1799 is stored. In at least one embodiment, the real hypervisor address space 1798 can be accessed via a hypervisor 1796, which virtualizes graphics acceleration module machines for the operating system 1795.
[0250] 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 1746. In at least one embodiment, there are two programming models in which the graphics acceleration module 1746 is shared by multiple processes and partitions: namely, time-shared and graphically directed sharing.
[0251] In this model, in at least one embodiment, the SystemHypervisor 1796 owns the Graphics Acceleration Module 1746 and makes its functionality available to all Operating Systems 1795. For a Graphics Acceleration Module 1746 to support virtualization by the SystemHypervisor 1796, in at least one embodiment, the Graphics Acceleration Module 1746 may meet certain conditions, such as: 1) An application job request must be autonomous (i.e., the state does not need to be maintained between jobs), or the Graphics Acceleration Module 1746 must provide a context saving and recovery mechanism.2) A graphics acceleration module 1746 guarantees that the job request of an application will be completed within a certain time period, including any translation errors, or the graphics acceleration module 1746 provides the possibility to interrupt the processing of a job, and 3) the graphics acceleration module 1746 must be guaranteed fairness between processes when operating in a directed common programming model.
[0252] In at least one embodiment, the application 1780 must execute a system call of the operating system 1795 with a graphics acceleration module type, a work descriptor (WD), an authority mask register (AMR) value, and a context save / restore area pointer (CSRP). In at least one embodiment, the graphics acceleration module type describes a specific acceleration function for a 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 1746 and can be in the form of a graphics acceleration module 1746 instruction, an effective address pointer to a user-defined structure, an effective address pointer to an instruction queue, or another data structure that describes the work to be performed by the graphics acceleration module 1746.
[0253] In 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. If the implementations of the accelerator integration circuit 1736 and the graphics acceleration module 1746 do not support a User Authority Mask Override Register (UAMOR) in at least one embodiment, an operating system can apply a current UAMOR value to an AMR value before an AMR is passed in a hypervisor call. The hypervisor 1796 can optionally apply a current AMR value before an AMR is placed in a process element 1783 in at least one embodiment.In at least one embodiment, CSRP is one of the registers 1745 that contain an effective address of a range in the effective address space 1782 of an application for the graphics acceleration module 1746 for storing and restoring context state. This pointer is optional in at least one embodiment if no state needs to be stored between jobs or if a job is prematurely terminated. In at least one embodiment, the context memory / restore area can be anchored in system memory.
[0254] Upon receiving a system call, the operating system 1795 can check whether the application 1780 is registered and has been granted permission to use the graphics acceleration module 1746. In at least one embodiment, the operating system 1795 then calls the hypervisor 1796 with the information shown in Table 3. Table 3 - Hypervisor call parameters from the operating system Parameter # Description 1 A working descriptor (WD) 2 An Authority Mask Register (AMR) value (possibly masked) 3 An effective address (EA) Context Backup / Restore Area Pointer (CSRP) 4 A process ID (PID) and optionally a thread ID (TID) 5 A virtual address (VA) Accelerator Usage Record Pointer (AURP) 6 Virtual address of a memory segment table pointer (SSTP) 7 A Logical Interrupt Service Number (LISN)
[0255] Upon receiving a hypervisor call, in at least one embodiment, the hypervisor 1796 checks whether the operating system 1795 is registered and has been granted permission to use the graphics acceleration module 1746. In at least one embodiment, the hypervisor 1796 then adds the process element 1783 to a linked process element list for a corresponding graphics acceleration module type 1746. In at least one embodiment, a process element can contain the information shown in Table 4. Table 4 - Process element information Parameter # Description 1 A working descriptor (WD) 2 An Authority Mask Register (AMR) value (possibly masked) 3 An effective address (EA) Context Backup / Restore Area Pointer (CSRP) 4 A process ID (PID) and optionally a thread ID (TID) 5 A virtual address (VA) Accelerator Usage Record Pointer (AURP) 6 Virtual address of a memory segment table pointer (SSTP) 7 A Logical Interrupt Service Number (LISN) 8 Break vector table derived from hypervisor call parameters 9 A status register (SR) value 10 A logical partition ID (LPID) 11 Real Address (RA) Hypervisor Accelerator Usage Record Pointer 12 Memory Description Registers (SDRs)
[0256] In at least one embodiment, the hypervisor initializes a plurality of registers 1745 for accelerator integration slices 1790.
[0257] In at least one embodiment, at least one in Fig. 17E component shown or described is used to implement procedures and / or functions related to the Fig.1-8 are described. In at least one embodiment, at least one component of Fig. 17E is used to cause access to a three-dimensional (3D) representation of an environment, the determination of one or more static features and one or more dynamic features of the 3D representation, the determination of one or more static density values, the determination of one or more dynamic density values, and / or the generation of one or more images based on the one or more static density values and the one or more dynamic density values. In at least one embodiment, at least one component of Fig.17E selects at least one aspect relating to the machine learning model(s) 110, the static hash encoder 104, the dynamic hash encoder 106, the flow hash encoder 108, the RGB mesh 130, the rendering module 120, the gaze direction module 112 and / or the processor 140 of Fig. 1, the scene breakdown 200 of Fig. 2, the image generation 300 of Fig. 3, the hash encoder 404, the hash encoder 424, the MLP 408, the MLP 428, the static RGB net 414, the dynamic RGB net 434 and / or the renderer 420 of Fig. 4, the hash encoder 504, the hash encoder 524, the MLP 508, the MLP 528, the RGB net 534 and / or the renderer 520 of Fig. 5, the static and dynamic decomposition 600 of Fig. 6, the procedure 700 of Fig. 7 and / or the 800 processor from Fig. 8 is described.
[0258] As it is in Fig.As shown in Figure 17F, at least one embodiment uses a unified memory addressable via a common virtual memory address space, which is used for accessing physical processor memories 1701(1) - 1701(N) and GPU memories 1720(1) - 1720(N). In this implementation, operations performed on the GPUs 1710(1) - 1710(N) use the same virtual / effective memory address space for accessing the processor memories 1701(1) - 1701(N) and vice versa, simplifying programmability. In at least one embodiment, a first section of a virtual / effective address space is allocated to the processor memory 1701(1), a second section to the second processor memory 1701(N), a third section to the GPU memory 1720(1), and so on.In at least one embodiment, this distributes an entire virtual / effective memory space (sometimes also referred to as effective address space) across each of the processor memory 1701 and GPU memory 1720, allowing each processor or GPU to access each physical memory with a virtual address assigned to that memory.
[0259] In at least one embodiment, the bias / coherence management circuit 1794A-1794E within one or more MMUs 1739A-1739E ensures cache coherence between the caches of one or more host processors (e.g., 1705) and GPUs 1710 and implements biasing procedures that specify in which physical memories certain data types should be stored. While in at least one embodiment multiple instances of the bias / coherence management circuit 1794A-1794E are located in Fig.As shown in Figure 17F, the bias / coherence circuit can be implemented within an MMU of one or more host processors 1705 and / or within the accelerator integration circuit 1736.
[0260] One embodiment allows GPU memory 1720 to be mapped as part of system memory and accessed using shared virtual memory (SVM) technology, without the performance drawbacks associated with full system cache coherence. In at least one embodiment, the ability to access GPU memory 1720 as system memory without the cumbersome cache coherence overhead provides an advantageous operating environment for GPU offloading. This arrangement allows the host processor 1705 software, in at least one embodiment, to set operands and access computational results without the overhead of conventional I / O DMA data copies. Such conventional copies, in at least one embodiment, involve driver calls, interrupts, and memory-mapping 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 1720 without cache coherence overhead can be critical for the execution time of an offloaded computation. In cases with significant streaming write memory traffic, the cache coherence overhead can, for example, significantly reduce the effective write bandwidth of a GPU 1710 in at least one embodiment. In at least one embodiment, the efficiency of operand setup, result access, and GPU computation can all play a role in determining the effectiveness of GPU offloading.
[0261] In at least one embodiment, the selection of a GPU bias and a host processor bias is controlled 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 (i.e., controlled by the granularity of a memory page) having 1 or 2 bits per GPU-connected memory page. In at least one embodiment, a bias table can be implemented in a stolen memory area of one or more GPU 1720 memories, with or without a bias cache in a GPU 1710 (e.g., to cache frequently / recently used entries of a bias table). Alternatively, in at least one embodiment, an entire bias table can be managed in a single GPU.
[0262] In at least one embodiment, before the actual access to a GPU memory, a bias table entry associated with each access to GPU memory 1720-1723 is accessed, which performs the following operations. First, in at least one embodiment, local requests from GPU 1710 that find their page in the GPU bias are forwarded directly to a corresponding GPU memory 1720. In at least one embodiment, local requests from a GPU that find their page in the host bias are forwarded to processor 1705 (e.g., via a high-speed connection). In at least one embodiment, requests from processor 1705 that find a requested page in the host processor bias are completed like a normal memory read access. Alternatively, requests directed to a GPU-biased or GPU-bound page can be forwarded to GPU 1710.In at least one embodiment, a GPU can transition a page into a host processor bias when it is not currently using that page. In at least one embodiment, the bias state of a page can 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.
[0263] In at least one embodiment, a mechanism for changing the bias state uses an API call (e.g., OpenCL) that in turn calls a GPU setup driver, which then sends a message to a GPU (or queues a command descriptor) to instruct it to change a bias state and, for some transitions, to perform a cache flushing operation on a host. In at least one embodiment, the cache flushing operation is used for a transition from the bias of the host processor 1705 to the bias of the GPU, but not for a reverse transition.
[0264] In one embodiment, cache coherence is maintained by temporarily rendering GPU-bound pages that cannot be cached by the host processor 1705. To access these pages in at least one embodiment, the processor 1705 may request access from the GPU 1710, which may not grant access immediately. Therefore, to reduce communication between the processor 1705 and the GPU 1710 in at least one embodiment, it is advantageous to ensure that GPU-bound pages are those required by a GPU but not by the host processor 1705, and vice versa.
[0265] Hardware structure(s) 1115 are used to implement one or more embodiments. Details of the hardware structure(s) 1115 can be found here in conjunction with the Fig. 9A and / or 9B must be specified.
