[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application incorporates the entire disclosure of concurrently filed U.S. Patent Application No. 18 / 220,162, entitled "APPLICATION PROGRAMMING INTERFACE TO INDICATE ALLOCATION OF OPERATIONS," for all purposes. Technical Field
[0003] At least one embodiment relates to an open radio access network (O-RAN) that distributes signal processing operations.For example, one or more APIs indicate a functional split of signal processing operations between one or more units. Background Art
[0004] Using O-RAN to process signals may include a default allocation of tasks between radio units (RUs) and distributed units (DUs). The default allocation of signal processing may be restrictive. For example, the default allocation of tasks may limit bandwidth, latency, or other network attributes that network users may wish to optimize. As another example, a network using default settings may use a significant amount of time and computing resources based on the default allocation, or may be less flexible. Therefore, the ability of the units to process signals may be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] In at least one embodiment, operations in 5G signal processing are statically distributed between the RU and DU (e.g., using a "7.2" split). However, this distribution may not always be ideal. In at least some embodiments, it may be advantageous for the RU and / or DU to perform more or fewer operations.
[0068] In at least one embodiment, the systems and methods implemented according to the present disclosure are used to execute an application programming interface (API) to instruct the allocation of wireless signal processing operations between one or more open radio access network (O-RAN) radio units (RUs) and one or more O-RAN distributed units (DUs) and / or otherwise perform the operations described herein. In at least one embodiment, the systems and methods implemented according to the present disclosure are used to execute an application programming interface (API) so that one or more software programs indicated by the API are assigned to one or more 5G DUs indicated by the API and / or otherwise perform the operations described herein.
[0069] In at least one embodiment, an open radio access network (O-RAN) allocates different signal processing operations between radio units (e.g., units used for transmit / receive, the O-RU 106 in O-RAN) and distributed units (e.g., O-DUs in O-RAN, units used for computationally intensive operations such as channel estimation) according to the 7.2 split. In at least one embodiment, the "7.2 split" is a version of how different signal processing operations are allocated to the RU or DU. In at least one embodiment, in 7.2, the O-RU 106 performs receive / transmit operations (e.g., receives an analog signal, samples it, and converts the analog signal to a digital signal), while the O-DU performs more intensive operations (e.g., channel estimation, demapping, and / or descrambling). However, in at least one embodiment, there are advantages to performing operations differently than in the 7.2 split version to optimize bandwidth (e.g., performing channel estimation in the O-RU rather than in the O-DU as in 7.2).
[0070] In at least one embodiment, one or more units in the system perform operations based on a functional partition (e.g., the allocation of functionality between the RU and the DU). In at least one embodiment, one or more APIs are used to communicate the partition information to allocate functionality between the RU and the DU. In at least one embodiment, by allowing the DU and the RU to handle different functional allocations, the network can meet different standards for different clients (e.g., autonomous vehicles will have different network performance compared to standard voice services).
[0071] In at least one embodiment, a processor is used to execute an API to indicate how to allocate 5G signal processing operations between the DUs and RUs of the O-RAN. In at least one embodiment, the input to the API is an identifier of one of several ways to split the operation (e.g., a function of a 5G or 6G network). In at least one embodiment, the processor executing the API causes the DU to receive information indicating which operations the DU is to perform and which operations the RU is to perform. When the DU receives the identifier, the DU can use the identifier to look up what function the DU should perform and what operation the RU is to perform. In at least one embodiment, the DU then provides the operation allocation to each RU, and each RU can use this information to configure itself accordingly.
[0072] In at least one embodiment, a processor is configured to execute an API to provide a specific library to an accelerator (e.g., a GPU) of a DU to perform its functions based on the allocation indicated by executing the first API (described above). In at least one embodiment, the CPU of the DU executes the API. In at least one embodiment, the input to the API is an identifier of the accelerator and an identifier from the first API (described above) indicating how operations should be allocated between the DU and the RU. The DU executes the API by using the identifier to locate a software kernel to schedule it onto the identified accelerator so that the accelerator can perform the operations allocated to the DU. In at least one embodiment, the processor using or executing the API can cause the O-RU or O-DU to skip, bypass, or otherwise skip functional operations. For example, the processor using the API can cause the O-RU or O-DU to skip or bypass a demapping operation because it is being performed by another unit (e.g., not the O-DU, but the O-RU). In at least one embodiment, the processor using the API can cause certain cells (e.g., antenna groups providing 5G or 6G) to have different functional partitioning than other cells. For example, the O-RUs of one cell group may perform more operations than the O-RUs of another cell group so that bandwidth can be saved or used differently in different cells or different parts of the network.
[0073] In the preceding and following descriptions, various techniques are described. For purposes of explanation, specific configurations and details are set forth to provide a thorough understanding of possible ways to implement the techniques. However, it will be apparent that the techniques described below can be practiced in different configurations without these specific details. Furthermore, well-known features may be omitted or simplified to avoid obscuring the described techniques.
[0074] Figure 11 is a block diagram illustrating a system 100 for distributing signal processing operations based at least in part on indicated partition 102 information, according to at least one embodiment. In at least one embodiment, the system 100 uses the partition 102 information (e.g., a partition 102 architecture identifier) to distribute one or more operations among one or more units. For example, the system 100 distributes the operations based on the partition 102 information identifying a functional partition for distributing the one or more operations (e.g., to adjust L1 acceleration of the system 100).
[0075] In at least one embodiment, system 100 performs communication 112 between DU 104 and RU 106, for example, using a first API that indicates split 102 information and / or otherwise performs operations described herein. In at least one embodiment, a CPU executing DU 104 receives split 102 information (e.g., from a network administrator or client), where the split 102 information indicates a split version, where each version corresponds to a different allocation of functionality between RU 106 and DU 104. In at least one embodiment, the unit (e.g., DU 104 and / or RU 106) performs the functionality corresponding to the split information, such as an indication of a split architecture. For example, input to the first API may be "split 7.3," where 7.3 is a split 102 indicating that RU 106 performs demodulation (rather than the standard 7.2 split where DU 104 performs demodulation). In at least one embodiment, when DU 104 receives the split 102 information, it can use this information to determine what functionality (e.g., demodulation) the DU 104 should perform and what functionality the RU 106 should perform, based on the version. For example, the DU 104 has a database that stores split 102 versions and corresponding functional allocations between the DU 104 and the RU 106. In at least one embodiment, after determining the split 102 information for the DU 104, the DU 104 provides the split 102 information to the RU 106, and the RU 106 can use it to configure itself accordingly. In at least one embodiment, the first API allows the O-RAN network to receive a split 102 version (including a version that is different from the standard) and then configure the network to perform according to the information indicating the functional split 102. For example, the processor includes one or more circuits that are configured to execute an application programming interface (API) to cause one or more DUs 104 to, at least in part, cause one or more functions to be performed by one or more RUs 106 based on input indicating allocation of one or more functions between one or more distributed units 104 and one or more radio units 106, and / or otherwise perform the operations described herein. For example, the input indicating the split 102 information indicating allocation of one or more functions includes an input indicating the functional split 102 (e.g., Figure 2 and / or Figure 3 The functional partitioning shown in (e.g., 202 or 302)) is described in detail.
[0076] In at least one embodiment, the system 100 performs communication 112 between the DU 104 and the RU 106, for example, by using a second API that allows an accelerator (e.g., a GPU) to use a specific library to perform its functions based at least in part on the received partition 102 information. In at least one embodiment, the CPU executing the DU 104 receives the partition 102 information and the accelerator ID (e.g., the GPU ID). In at least one embodiment, using the partition 102 information and the accelerator ID, the CPU looks up (e.g., in a database) what functions need to be performed based on the partition 102 version and what libraries the accelerator needs to use to perform these functions. In at least one embodiment, based on the one or more libraries found, the CPU can then configure the accelerator to perform the operations necessary to perform the functions for the partition 102 version. In at least one embodiment, the communication 112 includes an API that allows the DU 104 to find one or more libraries for different accelerators and then configure the accelerator to perform operations based on the one or more libraries. For example, the processor includes: one or more circuits for executing an application programming interface (API) so that the one or more processors indicate a library to be used to perform operations based at least in part on input indicating how to allocate one or more functions between one or more distributed units 104 and one or more radio units 106 and one or more instructions to one or more accelerators, and / or otherwise perform the operations described herein. In at least one embodiment, the library may include operations for performing specific 5G, 6G, or other wireless protocol operations, such as demapping, demodulation, modulation, or other signal processing operations. In at least one embodiment, the signal processing operations refer to fifth generation (5G), sixth generation (6G), or other wireless communication standards indicated by 802.11 IEEE.
[0077] In at least one embodiment, the system 100 performs communication 112 between the DU 104 and the RU 106, for example, by using a second API that allows an accelerator (e.g., a GPU) to use a specific library to perform its functions based at least in part on the received segmentation 102 information. In at least one embodiment, the accelerator includes one or more hardware accelerators, such as a GPU, an application-specific integrated circuit (ASIC), a system-on-chip (SoC), a data processing unit (DPU), or a combination thereof. In at least one embodiment, the APIs of the present disclosure can specify an accelerator ID (e.g., an identification, a processor ID, a memory location, a bus address) such that the APIs specify the functional segmentation of operations and which accelerators will execute which portions of the functional segmentation. In at least one embodiment, the APIs of the present disclosure specify a layer or portion of a layer of the O-RAN software stack (e.g., layer 1, layer 2, layer 3, or a portion thereof) that is a portion of the DU or RU to be executed by one or more accelerators based on the functional segmentation.
[0078] In at least one embodiment, the system 100 comprises a collection of one or more hardware and / or software computing resources having instructions that, when executed, perform one or more communication 112 processes, such as the processes described herein. In at least one embodiment, the system 100 is a software program executed on computer hardware, an application executed on computer hardware, and / or variations thereof. In at least one embodiment, one or more processes of the system 100 are executed by any suitable processing system or unit (e.g., a graphics processing unit (GPU), a general-purpose GPU (GPGPU), a parallel processing unit (PPU), a central processing unit (CPU)), a data processing unit (DPU) (described below) in any suitable manner, including sequentially, in parallel, and / or variations thereof. In at least one embodiment, the system 100 implements and executes the operations described herein using a machine learning training framework (e.g., PYTORCH, TENSORFLOW, BOOST, CAFFE, MICROSOFT COGNITIVE TOOLKIT / CNTK, MXNET, CHAINER, KERAS, DEEPLEARNING4J, and / or other training frameworks) to instruct the allocation of operations for processing wireless signals and / or to perform the operations. In at least one embodiment, as an example, training a neural network model includes using a server (e.g., an NVIDIA DGX server) that also includes at least a GPU (e.g., AMD MI200, VEGAL10, VEGO20, and ARCTURUS), an optimizer (e.g., ADAM OPTIMIZER), or a discriminator architecture (e.g., a discriminator architecture from face-vid2vid for training using a GAN loss).
[0079] In at least one embodiment, system 100 is comprised of modules (e.g., modules 1104-1110, see Figure 11 ) such that the system 100 executes an application programming interface (API) to instruct the allocation of wireless signal processing operations between one or more open radio access network (O-RAN) radio units (RUs) and one or more O-RAN distributed units (DUs). In at least one embodiment, the system 100 is composed of modules (e.g., modules 1104-1110, see Figure 11 ) is configured so that the system 100 executes an application programming interface (API) so that one or more software programs indicated by the API are assigned to one or more 5G DUs indicated by the API.

[0082] In at least one embodiment, fifth generation new radio ("5G-NR") is a radio access technology for mobile networks. In at least one embodiment, 5G-NR complies with the global standard for the air interface of 5G networks, as an example.

[0083] In at least one embodiment, a network interface controller (NIC) is a hardware component that connects one or more computing systems to one or more computing networks. In at least one embodiment, the NIC receives data to be processed by a first processor or a second processor (e.g., a hardware accelerator) and sends the data processed by the first processor or the second processor to another component in the O-RAN network (e.g., a base station).

In at least one embodiment, system 100 performs acceleration based at least in part on software-defined programmable L1 acceleration using an inline high PHY mode (e.g., using an L1 software library implemented at a "component" level rather than an end-to-end fixed pipeline) rather than existing fixed-function accelerators.

In at least one embodiment, L2+ 604 triggers uplink (UL) processing to L1, which sends the corresponding C-plane to the O-RU for UL reception and uses appropriate software libraries and dedicated computing resources to process the U-plane received from multiple O-RUs with different split architectures and returns the output of the L1 UL processing to the L2+ application. In at least one embodiment, discovering the capabilities of the O-RU 608 and / or 610 and configuring one or more cells supported by the O-RU can be combined into one step (e.g., a function call) or as separate API calls.
[0141] In at least one embodiment, the system 600 performs dynamic chaining of L1 functional blocks. For example, an O-DU 602 is serving an O-RU (e.g., 608 and / or 610), where the O-RU supports a 7.2 split architecture and a second O-RU supports a split architecture 7.2-x variant. In at least one embodiment, the O-DU L1 606 is an inline acceleration solution (e.g., a software-defined programmable HWA such as a GPU), where different software libraries implement different split architectures based at least in part on physical splits, such as different sets of signal processing blocks. In at least one embodiment, the L2+ 604 application, upon discovering the capabilities of the O-RU 608 and / or 610, assigns dedicated L1 compute resources and configures one or more cells supported by the O-RU 608 and / or 610, where the L2+ application configures the one or more cells supported by the O-RU based on the split architecture. For example, internally, L1 606 has a pool of different functional block implementations (e.g., in the same software library) that can be individually selected and then linked together in sequence to create an L1 processing pipeline. In at least one embodiment, L1 606 selects a set of functional blocks and / or components from the pool (e.g., based on functional partitioning) and links these components to create a high PHY processing pipeline. In at least one embodiment, Figure 7 Unlike the different software libraries in the previous examples shown in , L1 606 uses a different set of chained components to handle the uplink U-plane corresponding to the different architectures.
[0142] In at least one embodiment, the system 600 performs dynamic switching (e.g., turning on or off) of L1 functional blocks. For example, an O-DU 602 is serving an O-RU (e.g., 608 and / or 610), where the O-RU supports a 7.2 split architecture and a second O-RU supports a 7.2-x variant of the split architecture. In at least one embodiment, the O-DU L1 606 is an inline acceleration solution (e.g., a software-defined programmable HWA such as a GPU), where different software libraries implement different split architectures based at least in part on physical splits, such as different sets of signal processing blocks. In at least one embodiment, the L2+ 604 application, upon discovering the capabilities of the O-RU 608 and / or 610, assigns dedicated L1 compute resources and configures one or more cells supported by the O-RU 608, and / or the L2+ 604 application configures one or more cells supported by the O-RU 608 and / or 610 based on the architecture. For example, internally, L1 606 has a pre-linked L1 pipeline (e.g., with the same software library), with a set of functional blocks that can be selectively switched (e.g., turned on or off). In at least one embodiment, when a block is turned off, the interconnections of the blocks before and after it are reconfigured. In at least one embodiment, L1 606 selects a set of functional blocks (e.g., components) based on functional partitioning and reconfigures the L1 pipeline chain. In at least one embodiment, as an alternative to different software libraries (e.g., such as Figure 7 ), L1 606 uses different L1 reconfigured pipelines (eg, with different blocks turned on or off) to process the uplink U-plane corresponding to the split architecture.
[0143] In at least one embodiment, system 600 performs dynamic fusion of L1 functional blocks. For example, O-DU 602 is serving an O-RU (e.g., 608 and / or 610), where the O-RU supports a 7.2 split architecture and a second O-RU supports a 7.2-x variant of the split architecture. In at least one embodiment, O-DU L1 606 is an inline acceleration solution (e.g., a software-defined programmable HWA such as a GPU), where different software libraries implement different split architectures based at least in part on physical splits, such as different sets of signal processing blocks. In at least one embodiment, an L2+ 604 application, upon discovering the capabilities of O-RU 608 and / or 610, assigns dedicated L1 compute resources and configures cells supported by O-RU 608. The L2+ 604 application configures one or more cells supported by O-RU 608 and / or 610 based on the architecture, and a processor (e.g., processor 1102) performs selective fusion of enabled functional blocks to further optimize performance (e.g., customizable to the split architecture). In at least one embodiment, as an alternative to different software libraries (e.g., Figure 7), L1 606 uses a different L1 reconfiguration pipeline, in which turned-on blocks are selectively merged and the uplink U-plane corresponding to the split architecture is processed.

In at least one embodiment, the code is stored on a computer-readable storage medium in the form of a computer program that includes a plurality of computer-readable instructions that are executable by one or more processors. In at least one embodiment, the computer-readable storage medium is a non-transitory computer-readable medium. In at least one embodiment, at least some of the computer-readable instructions that can be used to perform process 700 are not stored using only transient signals (e.g., propagated transient electrical or electromagnetic transmissions). In at least one embodiment, the non-transitory computer-readable medium does not necessarily include non-transitory data storage circuitry (e.g., buffers, caches, and queues) within a transient signal transceiver.

In at least one embodiment, logic (eg, hardware, software, or a combination of hardware and software) performs process 700 .
[0147] For example, in process 700, the O-DU is serving the O-RU (e.g., 608 and / or 610, see Figure 6 ), wherein one O-RU supports a 7.2 split architecture and a second O-RU supports a 7.2-x variant of the split architecture. In at least one embodiment, process 700 includes one or more steps of configuring 704 a cell for functional split (e.g., 7.2-x and / or a 7.2-x variant), selecting 706 an L1 software library from a library pool, performing processing according to the functional split using 708 the library, and / or sending a success or failure response. In at least one embodiment, a processor uses 708 the library according to the functional split (e.g., indicated by functional split information), for example, the processor instantiates the library.
[0148] In at least one embodiment, once the processor executing process 700 uses the library 708, the process proceeds to decision block 710. In at least one embodiment, if the process is successful (e.g., the processing is performed according to the functional partition using the library 708), the decision in decision block 710 is "yes." In at least one embodiment, otherwise, the decision in decision block 710 is "no." In at least one embodiment, if the answer is "yes" in decision block 710, the process proceeds to end 712. In at least one embodiment, if the answer is "no" in decision block 710, the process re-attempts process 700 by continuing to step 704 and / or ends 712 with a failure indication.
[0149] In at least one embodiment, the O-DU L1 606 is an inline acceleration solution (e.g., a software-defined programmable HWA such as a GPU) in which different software libraries implement different partitioning architectures, such as different sets of signal processing blocks, based at least in part on the physical partitioning. In at least one embodiment, the L2+ 604 application, upon discovering the capabilities of the O-RU, selects 706 dedicated L1 compute resources based on the partitioning architecture and configures 704 one or more cells supported by the O-RU. In at least one embodiment, internally, in response, the L1 instantiates (e.g., using 708 libraries) execution instances of different software libraries dedicated to processing the L1 pipelines for the different partitions. In at least one embodiment, the L2+ triggers uplink (UL) processing to the L1, which sends the corresponding C-plane to the O-RU for UL reception, uses appropriate software libraries and dedicated compute resources to process the U-planes received from multiple O-RUs with different partitioning architectures, and returns the output of the L1 UL processing to the L2+ application. In at least one embodiment, discovering the capabilities and configuration of the O-RU supported by the O-RU (e.g., configuring one or more cells for functional segmentation in 704) can be combined into one step (e.g., a function call) or a separate API call. In at least one embodiment, the software continues normal operation after sending a success or failure response and / or then ends 712.

[0151] Figure 8800 is a flow chart illustrating a process 800 for accelerating dynamic linking of blocks of a library based at least in part on a partitioned architecture, according to at least one embodiment.

[0152] In at least one embodiment, part or all of process 800 (or any other process described herein, or variations and / or combinations thereof) is performed under the control of one or more computer systems configured with computer-executable instructions and implemented as code (e.g., computer-executable instructions, one or more computer programs, or one or more applications) that is executed on one or more processors by hardware, software, or a combination thereof. In at least one embodiment, the code is stored on a computer-readable storage medium in the form of a computer program that includes a plurality of computer-readable instructions that are executable by one or more processors.

In at least one embodiment, otherwise, the decision in decision block 810 is "no." In at least one embodiment, if the decision is "yes," the process proceeds to end 812. In at least one embodiment, if the decision in decision block 810 is "no," the process retries process 800 by continuing to step 804 and / or ends with a failure indication 812.
[0155] For example, O-DU 602 is serving an O-RU (e.g., 608 and / or 610, see Figure 6 ), where the first O-RU supports the 7.2 split architecture and the second O-RU supports the split architecture 7.2-x variant.

For example, internally, the L1 has a pool of different functional block implementations (e.g., in the same software library) that can be picked separately and then linked 808 in sequence to create the L1 processing pipeline. In at least one embodiment, the L1 selects 806 a set of functional blocks and / or components from the pool (e.g., based on functional partitioning) and links 808 these components to create a high PHY processing pipeline. In at least one embodiment, the L1 uses a different set of linked 808 components to process the uplink U-plane corresponding to the different architectures, rather than as Figure 7 In at least one embodiment, the software continues normal operation and / or then ends 812 when a response of success or failure is sent.

[0281] 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 controller 1336 or the second controller 1336). For example, in at least one embodiment, the ADAS system 1338 can be a backup and / or secondary computer that provides perception information to a backup computer rationality module.

[0282] 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.
[0283] In at least one embodiment, the supervisory MCU can be configured to run a neural network that is trained and configured to determine, based at least in part on outputs from the primary and secondary computers, conditions under which the secondary computer provides a false alarm. 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.
[0284] 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 bug in the software running on the main computer, and a different software code running on the auxiliary computer provides the same 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 did not cause a significant error.
[0285] 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.

[0320] Figure 18AAn exemplary architecture is shown in which multiple GPUs 1810-1813 are communicatively coupled to multiple multi-core processors 1805-1806 via high-speed links 1840-1843 (e.g., buses / point-to-point interconnects, etc.).

[0321] Furthermore, in one embodiment, two or more GPUs 1810-1813 are interconnected via high-speed links 1829-1830, which may be implemented using the same or different protocols / links as used for high-speed links 1840-1843.

Alternatively, the same protocol / 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 .
[0322] In one embodiment, each multi-core processor 1805-1806 is communicatively coupled to processor memory 1801-1802 via memory interconnects 1826-1827, respectively, and each GPU 1810-1813 is communicatively coupled to GPU memory 1820-1823 via GPU memory interconnects 1850-1853, respectively. Memory interconnects 1826-1827 and 1850-1853 can utilize the same or different memory access technologies. By way of example and not limitation, processor memory 1801-1802 and GPU memory 1820-1823 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 one embodiment, some portion of the processor memory 1801-1802 may be volatile memory, while another portion may be non-volatile memory (eg, using a two-level memory (2LM) hierarchy).
[0323] As described herein, although the various processors 1805-1806 and GPUs 1810-1813 may each be physically coupled to a specific memory 1801-1802, 1820-1823, a unified memory architecture may be implemented in which the same virtual system address space (also referred to as an "effective address" space) is distributed across the various physical memories. For example, the processor memories 1801-1802 may each contain 64GB of system memory address space, and the GPU memories 1820-1823 may each contain 32GB of system memory address space (resulting in a total addressable memory size of 256GB in this example).
[0324] Figure 18B 1807 and a graphics acceleration module 1846. 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. Alternatively, the graphics acceleration module 1846 may be integrated on the same package or chip as the processor 1807.
[0325] In at least one embodiment, the illustrated processor 1807 includes a plurality of cores 1860A-1860D, each having a translation lookaside buffer 1861A-1861D and one or more caches 1862A-1862D. In at least one embodiment, the cores 1860A-1860D may include various other components, not shown, for executing instructions and processing data. In at least one embodiment, the 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 the caches 1862A-1862D and shared by each group of cores 1860A-1860D. For example, one embodiment of the processor 1807 includes 24 cores, each 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. The processor 1807 and the graphics acceleration module 1846 are connected to the system memory 1814, which may include Figure 18A Processor memory 1801-1802 in.
[0326] Coherence is maintained for data and instructions stored in the various caches 1862A-1862D, 1856, and system memory 1814 via inter-core communication over a coherence bus 1864. For example, each cache may have cache coherence logic / circuitry associated therewith to communicate over the coherence bus 1864 in response to detecting a read or write to a particular cache line. In one implementation, a cache snooping protocol is implemented over the coherence bus 1864 to snoop cache accesses.
[0327] In 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 (e.g., a PCIe bus, NVLink, etc.), and interface 1837 connects graphics acceleration module 1846 to link 1840.
[0328] In one implementation, 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, 1832, N of the graphics acceleration module. The graphics processing engines 1831, 1832, N may each comprise a separate graphics processing unit (GPU). Alternatively, the graphics processing engines 1831, 1832, N may selectively comprise 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 1831-1832, N, or the graphics processing engines 1831-1832, N may be individual GPUs integrated into a common package, line card, or chip.
[0329] In 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. The MMU 1839 may also include a translation lookaside buffer ("TLB") (not shown) for caching virtual / effective-to-physical / real address translations. In one implementation, cache 1838 may store commands and data for efficient access by the graphics processing engines 1831-1832, N. In at least one embodiment, data stored in cache 1838 and graphics memory 1833-1834, M is kept 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 1833-1834, M (e.g., sending updates related to modifications / accesses of cache lines on processor caches 1862A-1862D, 1856 to cache 1838 and receiving updates from cache 1838).
[0330] A set of registers 1845 stores context data for threads executed by graphics processing engines 1831-1832, 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 context 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 one embodiment, interrupt management circuitry 1847 receives and processes interrupts received from system devices.
[0331] In one implementation, the MMU 1839 converts virtual / effective addresses from the graphics processing engine 1831 into real / physical addresses in the system memory 1814. One embodiment of the accelerator integrated circuit 1836 supports multiple (e.g., 4, 8, 16) graphics accelerator modules 1846 and / or other accelerator devices. 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 one embodiment, a virtualized graphics execution environment is presented in which the resources of the graphics processing engines 1831-1832, 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 processing requirements and priorities associated with the VMs and / or applications.
[0332] 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. In addition, 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 1831-1832.
[0333] Because the hardware resources of graphics processing engines 1831-1832, 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 1831-1832, N so that they appear as independent units to the system.
[0334] In at least one embodiment, one or more graphics memories 1833-1834, M are respectively coupled to each graphics processing engine 1831-1832, N. Graphics memories 1833-1834, M store instructions and data, which are processed by each graphics processing engine 1831-1832, N. Graphics memories 1833-1834, 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.
[0335] In one embodiment, to reduce data traffic on link 1840, biasing techniques can be used to ensure that the data stored in graphics memory 1833-1834, M is the data most frequently used by graphics processing engines 1831-1832, N, and preferably 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 core (and preferably not graphics processing engines 1831-1832, N) in the core's cache 1862A-1862D, 1856 and system memory 1814.
[0336] Figure 18C Another exemplary embodiment is shown in which an accelerator integrated circuit 1836 is integrated into the processor 1807. In this embodiment, the graphics processing engines 1831-1832, N communicate directly with the accelerator integrated circuit 1836 via interfaces 1837 and 1835 (which may also utilize any form of bus or interface protocol) over a high-speed link 1840. The accelerator integrated circuit 1836 can perform operations related to Figure 18B The operations described above are identical 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.
[0337] In at least one embodiment, the graphics processing engines 1831-1832, 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 the graphics processing engines 1831-1832, N, thereby providing virtualization within a VM / partition.
[0338] In at least one embodiment, graphics processing engines 1831-1832,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 1831-1832,N to allow each operating system to access them. For a single-partition system without a hypervisor, the operating system owns graphics processing engines 1831-1832,N. In at least one embodiment, the operating system can virtualize graphics processing engines 1831-1832,N to provide access to each process or application.
[0339] In at least one embodiment, the graphics acceleration module 1846 or individual graphics processing engines 1831-1832,N use a process handle to select a process element. In one embodiment, the process element is stored in the 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 1831-1832,N (i.e., calling system software to add the process element to the process element linked list). In at least one embodiment, the lower 16 bits of the process handle can be the offset of the process element in the process element linked list.
[0340] Figure 18D An exemplary accelerator integrated slice 1890 is shown. As used herein, a "slice" comprises a designated portion of the processing resources of an accelerator integrated circuit 1836. An application is an effective address space 1882 in system memory 1814 that stores process elements 1883. In one embodiment, process elements 1883 are stored in response to a GPU call 1881 from an application 1880 executing on processor 1807. Process elements 1883 contain the process state of the corresponding application 1880. A work descriptor (WD) 1884 contained in process element 1883 may be a single job requested by the application, or may contain a pointer to a job queue. In at least one embodiment, WD 1884 is a pointer to a job request queue in the application's address space 1882.
[0341] The graphics acceleration module 1846 and / or the individual graphics processing engines 1831-1832, N can be shared by all processes or a subset of processes in the system. In at least one embodiment, an infrastructure for setting process state and sending WD 1884 to the graphics acceleration module 1846 to start a job in a virtualized environment can be included.
[0342] In at least one embodiment, a dedicated process programming model is implementation-specific. In this model, a single process owns either a graphics acceleration module 1846 or an individual graphics processing engine 1831. Since the hypervisor initializes the accelerator integrated circuit for the owning partition when the graphics acceleration module 1846 is owned by a single process, the operating system initializes the accelerator integrated circuit 1836 for the owning process when the graphics acceleration module 1846 is assigned.
[0343] In operation, the WD fetch unit 1891 in the accelerator integrated slice 1890 fetches the next WD 1884, which includes an indication of work to be completed by one or more graphics processing engines of the graphics acceleration module 1846. Data from 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. The interrupt management circuitry 1847 can process interrupt events 1892 received from the graphics acceleration module 1846. When executing graphics operations, effective addresses 1893 generated by the graphics processing engines 1831-1832, N are converted into real addresses by the MMU 1839.
[0344] In one embodiment, the same set of registers 1845 is replicated for each graphics processing engine 1831-1832, N, and / or graphics acceleration module 1846, and the registers 1845 can be initialized by the hypervisor or operating system. Each of these replicated registers can be included in the accelerator integration slice 1890. Example registers that can be initialized by the hypervisor are shown in Table 1.
[0345]
[0346] Example registers that may be initialized by the operating system are shown in Table 2.
[0347]
[0348] In one embodiment, each WD 1884 is specific to a particular graphics acceleration module 1846 and / or graphics processing engine 1831-1832, N. It contains all the information needed by the graphics processing engine 1831-1832, N to complete the work, or it can be a pointer to a memory location where the application has set up a command queue for the work to be done.
[0349] Figure 18E 1896 , which virtualizes the graphics acceleration module engine for the operating system 1895.
[0350] 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. There are two programming models in which the graphics acceleration module 1846 is shared by multiple processes and partitions: time-sliced sharing and graphics-directed sharing.
[0351] In this model, the hypervisor 1896 owns the graphics acceleration module 1846 and makes its functionality available to all operating systems 1895. For the graphics acceleration module 1846 to support virtualization through the hypervisor 1896, the graphics acceleration module 1846 may adhere to the following: (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.
[0352] In at least one embodiment, an application 1880 is required to make an operating system 1895 system call using a graphics acceleration module 1846 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 1846 type describes the target acceleration function for the system call. In at least one embodiment, the graphics acceleration module 1846 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 describing work to be performed by the graphics acceleration module 1846. In 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 that of an application setting the AMR. If the implementation of the accelerator integrated circuit 1836 and graphics acceleration module 1846 does not support the User Authority Mask Override Register (UAMOR), the operating system can apply the current UAMOR value to the AMR value before passing the AMR in the hypervisor call. Hypervisor 1896 can optionally apply the current privilege mask overwrite register (AMOR) value before placing the AMR into process element 1883. In at least one embodiment, CSRP is one of registers 1845 that contains the effective address of an area in the application's address space 1882 for graphics acceleration module 1846 to save and restore context state. 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 can be fixed system memory.
[0353] Upon receiving the system call, the operating system 1895 may verify that the application 1880 has been registered and granted permission to use the graphics acceleration module 1846. The operating system 1895 then uses
[0354] The information shown in Table 3 is used to call the management program 1896.
[0355]
[0356] Upon receiving the hypervisor call, the hypervisor 1896 verifies that the operating system 1895 has registered and been granted permission to use the graphics acceleration module 1846. The hypervisor 1896 then places the process element 1883 into a linked list of process elements of the corresponding graphics acceleration module 1846 type. The process element may include the information shown in Table 4.
[0357]
[0358] In at least one embodiment, the hypervisor initializes the plurality of accelerator integrated slice 1890 registers 1845 .
[0359] like Figure 18F As shown, in at least one embodiment, a unified memory is used that is addressable via a common virtual memory address space for accessing physical processor memories 1801-1802 and GPU memories 1820-1823. In this implementation, operations executed on GPUs 1810-1813 utilize the same virtual / effective memory address space to access processor memories 1801-1802, 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, a second portion is allocated to second processor memory 1802, a third portion is allocated to GPU memory 1820, 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 memories 1801-1802 and GPU memories 1820-1823, thereby allowing any processor or GPU to access that memory using a virtual address mapped to any physical memory.
[0360] 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 GPUs 1810-1813 and implements biasing techniques that indicate the physical memory where certain types of data should be stored. 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 .
[0361] One embodiment allows GPU attached memory 1820-1823 to be mapped as part of system memory and accessed using shared virtual memory (SVM) technology, but without suffering the performance drawbacks associated with full system cache coherence. In at least one embodiment, the ability to access GPU attached memory 1820-1823 as system memory without the heavy cache coherence overhead provides a favorable operating environment for GPU offloading. This arrangement allows software of the host processor 1805 to set operands and access calculation results without the overhead of traditional I / O DMA data copies. Such traditional copies include driver calls, interrupts, and memory mapped I / O (MMIO) accesses, which are all less efficient than simple memory accesses. In at least one embodiment, the ability to access GPU attached memory 1820-1823 without cache coherence overhead can be critical to the execution time of the offloaded calculation. For example, in situations with large amounts of streaming write memory traffic, cache coherence overhead can significantly reduce the effective write bandwidth seen by the GPUs 1810-1813. In at least one embodiment, efficiency of operand setup, efficiency of result access, and efficiency of GPU computation may play a role in determining the effectiveness of GPU offloading.
[0362] In at least one embodiment, the selection of GPU bias and host processor bias is driven by a bias tracker data structure. For example, a bias table can be used, which can be a page-granular structure (e.g., controlled at the granularity of a memory page) that includes 1 or 2 bits per GPU-attached memory page. In at least one embodiment, the bias table can be implemented in the stolen memory range of one or more GPU-attached memories 1820-1823, with or without a bias cache in GPUs 1810-1813 (e.g., to cache frequently / recently used entries in the bias table). Alternatively, the entire bias table can be maintained within the GPU.
[0363] In at least one embodiment, before actually accessing the GPU memory, the bias table entry associated with each access to the GPU attached memory 1820-1823 is accessed, resulting in the following operations. First, local requests from GPUs 1810-1813 whose pages are found in the GPU bias are forwarded directly to the corresponding GPU memory 1820-1823. Local requests from the GPU whose pages are found in the host bias are forwarded to processor 1805 (e.g., via a high-speed link as described above). In one embodiment, a request from processor 1805 to find the requested page in the host processor bias completes a request similar to a normal memory read. Alternatively, a request to a GPU biased page can be forwarded to GPUs 1810-1813. 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.
[0364] One mechanism for changing the bias state employs an API call (e.g., OpenCL), which 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.
[0365] In one embodiment, cache coherence is maintained by temporarily rendering GPU-biased pages that cannot be cached by host processor 1805. To access these pages, processor 1805 may request access from GPU 1810, which may or may not immediately grant access. Therefore, 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.
