[0061] Many specific details have been set forth to provide a more thorough understanding of at least one embodiment. However, it will be apparent to those skilled in the art that these inventive concepts can be practiced without one or more of these specific details.
[0062] In at least one embodiment, in an Open Radio Access Network (“O-RAN”) deployment, one or more central processing units (“CPUs”) handle functional operations as part of a distributed unit (“DU”) or a centralized unit (“CU”). In at least one embodiment, in an O-RAN deployment, one or more CPUs can offload computationally intensive algorithm operations (such as physical layer signal processing, game processing, and video processing) to hardware accelerators in lower layers of the O-RAN network protocol stack. In at least one embodiment, the hardware accelerator can be a GPU, a field-programmable gate array (“FPGA”), an application-specific integrated circuit (“ASIC”), a system-on-a-chip (“SoC”), or other processors specifically designed for accelerated processing (e.g., one or more PPUs). In at least one embodiment, the hardware accelerators provide performance enhancements to processing operations in the O-RAN because they are designed to accelerate processing. For example, a GPU can execute thousands of operations in parallel compared to a CPU that performs operations serially.
[0063] In at least one embodiment, a 5G-NR service provider uses O-RAN to offer a range of services as part of “network slicing,” where different network slices of the 5G-NR network provide different types of services corresponding to different qualities of service (“QoS”). For example, a 5G-NR service provider provides one or more cells in a 5G-NR network with network slices employing enhanced mobile broadband (“eMBB”), ultra-reliable low-latency communication (“URLLC”), massive machine-type communication (“mMTC”), and / or vehicle-to-everything (“V2X”), where each service type has a different QoS; for example, URLLC is associated with ultra-low latency when handling 5G-NR workloads. In at least one embodiment, a cell refers to a portion of a 5G-NR network divided into geographical areas (e.g., 5G small cells). In at least one embodiment, a cell refers to a portion of a 5G-NR network operating using different frequency ranges or bands (e.g., macrocells, microcells, femtocells, or picocells).
[0064] In at least one embodiment, the hardware accelerator may have different capabilities for handling different types of 5G-NR workloads (e.g., workloads in different network slices with different QoS requirements). For example, a particular GPU or GPU group may inherently be better than a CPU for executing game-related mMTC workloads due to its parallel processing architecture; as another example, an FPGA or FPGA group programmed for low-latency workloads may be better than a CPU for executing URLLC workloads to meet QoS requirements because the programming is designed to reduce latency in the FPGA or FPGA group.
[0065] In at least one embodiment, applications deployed on an O-RAN network may be unaware of whether hardware accelerators in lower layers (e.g., Layer 1) are optimized for performing specific workloads to meet QoS requirements. More specifically, without determining what QoS requirements a hardware accelerator can meet, the application assumes that the hardware accelerator is standard and can meet predefined QoS requirements that may fall short of the capabilities of specialized hardware accelerators (e.g., newly designed GPUs optimized for machine learning operations), potentially leading to underutilization of hardware accelerator resources.
[0066] To illustrate the different capabilities of hardware accelerators and reduce underutilization of hardware accelerators designed for or specifically designed to handle workloads exceeding predefined standards, in at least one embodiment, apparatus, systems, and technologies execute one or more APIs that facilitate data communication between Layer 2 (“L2”) and Layer 1 (“L1”) of the O-RAN network protocol stack, enabling L2 and L1 to improve (e.g., optimize) the utilization of hardware accelerator resources in L1 to meet QoS requirements. In at least one embodiment, the one or more APIs may be executed by one or more processors, as described below, to exchange information between L2 and L1 of the O-RAN network protocol stack, allowing applications to determine, via L2, what QoS requirements one or more resources (e.g., hardware accelerators in L1) can meet when handling 5G-NR workloads in 5G-NR cells.
[0067] In at least one embodiment, the one or more APIs may be executed by one or more processors, as described below, to determine the maximum number of 5G-NR cells that resources in L1 can support while meeting required QoS requirements. For example, an application may use a set of APIs to determine how many 5G-NR cell resources in L1 can support URLLC workloads. Figures 3 to 6 The one or more APIs are disclosed in more detail. In at least one embodiment, because the application queries L1 to determine the maximum number of 5G-NR cells that can be supported while meeting quality requirements, the underutilization of hardware accelerators in L1 is reduced, since the application has queried the maximum number of cells that the resources in L1 can support while meeting quality parameters higher than predefined standards.
[0068] Figure 1 This is a schematic overview block diagram of a network protocol stack 100 according to at least one embodiment. In at least one embodiment, the network protocol stack 100 corresponds to or is used to perform one or more operations of an O-RAN network protocol stack or other network protocol stack for providing 5G-NR services. In other embodiments, the network protocol stack 100 corresponds to providing sixth-generation (6G) new radio network services or other wireless communication protocol stacks (e.g., any 3GPP wireless communication standard). In at least one embodiment, the network protocol stack 100 is used to support... Figures 34-38 and Figure 40 The network is publicly available in China.
[0069] Figure 1This includes a network protocol stack 100, an application 105, a layer 2 (“L2”) or higher layer 110 (also referred to as “L2+”), a layer 2 to layer 1 interface 115 (also referred to as “L2-L1 interface”), a driver 120, a first processor 125, a second processor 130, and a network interface controller 135. In at least one embodiment, L2 is associated with the 5G-NR data link layer, which is responsible for scheduling functions related to 5G-NR workloads. In at least one embodiment, layer 1 (“L1”) refers to the physical layer of the RAN protocol stack, which may be implemented as an L1 software library running on the first processor 125 (e.g., CPU) and / or the second processor 130 (e.g., an accelerated L1 run by an FPGA, GPU, ASIC, or SoC). In at least one embodiment, a layer refers to an abstraction of hardware that performs the functions or operations of a system, network, or computer; for example, L2 is an abstraction of hardware that performs data link and scheduling operations of an O-RAN network, and L1 is an abstraction of real-time hardware operations that perform physical layer operations of an O-RAN network (e.g., an O-RAN network). For example, a layer corresponds to an Open Systems Interconnection (OSI) model (e.g., L1, L2, L3) exposed by one or more interfaces used to handle the functions or operations of 5G-NR.
[0070] In at least one embodiment, application 105 is a RAN protocol stack program running on a host CPU (e.g., a first processor 125). For example, application 105 relates to software for a service provider of 5G-NR, used to provide eMBB, URLLC, mMTC, and / or V2X for one or more cells in a 5G-NR network. Although Figure 1 The diagram shows an application 105, but several applications can run on the network protocol stack 100, each application 105 providing the same or different services.
[0071] In at least one embodiment, the L2-L1 interface 115 enables application 105 to communicate with L1 and enables driver 120 in L1 to control first processor 125, second processor 130, and network interface controller 135. In at least one embodiment, application 105 uses L2-L1 interface 115 and one or more APIs to determine how many 5G-NR cells an L1 resource (e.g., a hardware accelerator) can concurrently support, schedule or prioritize workloads handled by the L1 resource, and perform operations to reconfigure or update the L1 resource as traffic conditions in the 5G-NR network change (see [link to API description] for more details on the one or more APIs). Figures 3 to 5In at least one embodiment, the L2-L1 interface 115 is an interface such as the fifth-generation functional application programming interface (5G FAPI), and / or a variant thereof. Figure 7 Further details regarding the L2-L1 interface are disclosed herein. In at least one embodiment, the L2-L1 interface 115 is connected to... Figure 7 It communicates with the Accelerated Abstraction Layer (AAL) interface disclosed in the document.
[0072] In at least one embodiment, driver 120 includes libraries for operating the first processor 125, the second processor 130, and the network interface controller 135. In at least one embodiment, driver, also referred to as a device driver, is a computer program that operates, controls, or otherwise provides an interface with various hardware, such as hardware accelerator devices and network communication / interface devices. In at least one embodiment, driver 120 includes one or more functions, processes, libraries, interfaces, and / or variations thereof that support the L2-L1 interface 115. In at least one embodiment, driver 120 is implemented such that the functionality of the L2-L1 interface 115 can be appropriately processed in relation to the first processor 125, the second processor 130, and the network interface controller 135.
[0073] In at least one embodiment, the first processor 125 is a processor with one or more circuits for performing operations corresponding to the network protocol stack 100. For example, the first processor 125 is a CPU configured to perform or operate a DU or CU of the O-RAN. In at least one embodiment, the second processor 130 is a hardware accelerator. The hardware accelerator may be a graphics processing unit (GPU), a field-programmable gate array (FPGA), an application-specific integrated circuit (ASIC), a system-on-a-chip (SoC), or other processors (e.g., parallel processing units) specifically designed to improve performance processing. In at least one embodiment, the first processor 125 (e.g., a CPU running a DU in the O-RAN network) can offload computationally intensive algorithms (such as physical (PHY) layer signal processing, game-related processing, video processing, and encryption processing) to the second processor 130 (e.g., a hardware accelerator).
[0074] In at least one embodiment, a network interface controller (NIC) 135 is a hardware component that connects one or more computing systems to one or more computing networks. In at least one embodiment, NIC 135 receives data to be processed by a first processor 125 or a second processor 130 (e.g., a hardware accelerator) and transmits the data processed by the first processor 125 or the second processor 130 to another component (e.g., a base station) in the O-RAN network. In at least one embodiment, NIC 135 receives data to be transmitted via an Accelerated Abstraction Layer interface (see... Figure 7 The NIC 135 processes data through one or more functions of the Accelerated Abstraction Layer interface and transmits the data processed by one or more functions of the Accelerated Abstraction Layer interface. In at least one embodiment, as part of providing 5G-NR services, the NIC 135 interacts with a Remote Radio Head (RRH), also known as a Remote Radio Unit (RRU).
[0075] Figure 2 A process flowchart for processing workloads of one or more 5G-NR cells according to at least one embodiment is shown. In at least one embodiment, a processor including one or more circuits or a system including one or more processors executes process 200 to process the O-RAN network protocol stack (e.g., such as...). Figure 1 The 5G-NR workload of the network protocol stack 100 shown.
[0076] In at least one embodiment, part or all of process 200 (or any other process described herein, or variations and / or combinations thereof) is executed under the control of one or more computer systems configured with computer-executable instructions and is implemented by hardware, software, or a combination thereof as code (e.g., computer-executable instructions, one or more computer programs, or one or more application programs) that executes jointly on one or more processors. In at least one embodiment, the code is stored in the form of a computer program on a computer-readable storage medium comprising a plurality of computer-readable instructions 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 available for executing process 200 are not stored using only transient signals (e.g., propagating 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 transceiver of transient signals. In at least one embodiment, process 200 is executed at least partially on a computer system (such as those described elsewhere in this disclosure). In at least one embodiment, logic (e.g., hardware, software, or a combination of hardware and software) executes process 200. In at least one embodiment, process 200 may begin with determination operation 205 and proceed to mapping operation 210.
[0077] In at least one embodiment, at determination operation 205, one or more processors execute an API to determine the number of cells that can be concurrently processed by one or more hardware accelerators in L1 based on quality parameters. In at least one embodiment, the quality parameters relate to QoS requirements for processing workloads, such as quality thresholds to be met, which correspond to latency, throughput, reliability, and / or connectivity for processing one or more workloads corresponding to 5G-NR cells. In at least one embodiment, the quality parameters correspond to a Key Performance Indicator (KPI) (also referred to as “performance metrics”) matrix that can be accessed by the hardware accelerators processing one or more workloads so that input quality parameters from the API can be used by L1 to query (or determine) the relevant KPIs for the workload to meet the quality parameters. For example, in determination operation 102, one or more processors executing L2+ applications negotiate with one or more processors providing L1 in the O-RAN network to determine how many 5G-NR cells the hardware acceleration resources in L1 can support to meet the URLLC or mMTB workloads of these cells. In such an example, L1 can query hardware accelerator resources (such as GPUs, CPUs, FPGAs, ASICs, and / or SoCs) to determine how many 5G cells they can support while meeting the quality parameters of URLLC or mMTB workloads. More details about the API and the determination process are available in [link to API documentation]. Figure 3 China has made it public, such as Figure 2 As shown by "A" in the diagram.
[0078] At mapping operation 210, one or more processors execute an API to map a specific 5G-NR cell (e.g., cell ID) to hardware accelerator resources in L1, which will handle workloads to meet specific quality parameters negotiated by the API in determination operation 102. In at least one embodiment, one or more processors providing an L2+ or L2 application provide a cell identification number (e.g., cell ID) to one or more processors providing L1, so that L1 can receive the cell ID for mapping a specific hardware accelerator to an L1 resource. In at least one embodiment, after determination operation 205, the application has learned the maximum number of cells that L1 can support while meeting the quality parameters, so mapping operation 210 further specifies the cell IDs and the L1 hardware resources that will handle the workloads of these cells. In at least one embodiment, the API can respond to whether the mapping from cell ID to hardware accelerator resource is successful (e.g., "1") or unsuccessful (e.g., "0"). Further details about the API and mapping operation 210 are provided in [link to API documentation]. Figure 4 China has made it public, such as Figure 2 As shown by "B" in the diagram.
[0079] At algorithm selection operation 215, one or more processors execute an API to select an algorithm for processing 5G-NR workloads. In at least one embodiment, one or more processors providing L1 have access to a library including different processing algorithms (e.g., one or more techniques) to process specific workloads to meet quality parameters, such as a low-latency algorithm with low-latency quality parameters for processing the workload, or a high-throughput algorithm designed to process the workload to meet high-throughput quality parameters. In at least one embodiment, one or more processors including one or more circuits are configured to schedule workload processing sequentially or in parallel. In at least one embodiment, one or more processors execute an API that determines whether to process the workload sequentially or in parallel to meet quality parameters. Further details about the API and operation 215 are provided in [link to API]. Figure 5 China has made it public, such as Figure 2 As shown by "C" in the diagram.
[0080] At workload execution operation 220, in at least one embodiment, one or more processors execute one or more APIs to perform workloads that have been set up and mapped based on determination operation 102, mapping operation 210, and selection algorithm operation 215. In at least one embodiment, L2 may provide information related to the number of cells that the hardware resources in L1 can support to the O-RAN Service Management and Coordinator (SMO), thereby determining updated scheduling information. In at least one embodiment, one or more processors execute one or more APIs from 5G FAPI and / or variations thereof to perform one or more workloads. Figure 7 Further details regarding the use of the 5G FAPI or its variants to perform one or more workloads have been disclosed.
[0081] At traffic condition determination operation 225, in at least one embodiment, one or more processors or systems executing an application (e.g., an L2 or L2+ application) determine that traffic conditions have changed based on traffic monitoring of the network (e.g., a 5G-NR network supported by a service provider). In at least one embodiment, if one or more processors or systems executing the application determine that traffic conditions have changed (e.g., between day and night, or based on providing new 5G-NR services for different network slices), the one or more processors or systems executing the application determine a new number of cells that can be processed concurrently based on quality parameters (e.g., as in determination operation 205, but with new quality parameters corresponding to the changed traffic conditions). For example, if an application receives a request to change from URLLC to mMTB service, such an application determines new quality parameters based on the new service mMTB and requests to determine the maximum number of cells that resources in L1 can support based on the new quality parameters. In at least one embodiment, the one or more processors or systems executing the application determine that the traffic conditions have not changed, and the one or more processors or systems executing the application determine to continue executing the workload to support 5G-NR cells (e.g., those already mapped by mapping operation 210).
[0082] Following traffic condition determination operation 225, in at least one embodiment, one or more circuits may repeat process 200 or a portion thereof, for example, for a new application requesting the use of the hardware accelerator in L1. In at least one embodiment, traffic condition determination operation 225, including one or more circuits, one or more processors or systems, may terminate process 200 (e.g., the application has been completed to provide 5G-NR service).
[0083] Figure 3 According to at least one embodiment, it includes a network protocol stack 100 for processing (see... Figure 1 A more detailed process flowchart for the workload. (e.g.) Figure 2 The "A" is indicated in the text. Figure 3 Further details are provided regarding whether it can be integrated into process 300 or executed by an API. In at least one embodiment, process 300 is executed by one or more circuits to process the O-RAN network protocol stack (e.g., such as...). Figure 1 The 5G-NR workload of the network protocol stack 100 shown.
[0084] In at least one embodiment, process 300 (or any other process described herein, or variations and / or combinations thereof) is partially or entirely executed under the control of one or more computer systems configured with computer-executable instructions, and is implemented by hardware, software, or a combination thereof as code (e.g., computer-executable instructions, one or more computer programs, or one or more application programs) that executes jointly on one or more processors. In at least one embodiment, at least some of the computer-readable instructions available for executing process 300 are not stored using merely transient signals (e.g., propagating transient electrical or electromagnetic transmissions). In at least one embodiment, process 300 is executed at least partially on computer systems (such as those described elsewhere in this disclosure). In at least one embodiment, process 300 is executed logically (e.g., by hardware, software, or a combination of hardware and software). In at least one embodiment, process 300 may begin with a call operation 310 and proceed to a response operation 315.
[0085] In at least one embodiment, at call operation 310, the application calls an API to query how many 5G-NR cells one or more L1 resources can support while meeting quality parameters (e.g., threshold QoS). In at least one embodiment, the API is referred to as the "QoS_config" API. In at least one embodiment, the API can receive input parameters, such as a QoS array (pointers to an array of integers) that includes quality parameters corresponding to one or more QoS requirements for processing one or more workloads corresponding to one or more 5G-NR cells. In at least one embodiment, the application calls the API and provides only the QoS array as input to determine how many maximum L1s can be supported while meeting the quality requirements in the QoS array. In at least one embodiment, the application calls the API to send a list of QoS requirements (e.g., [int Q1, int Q2, int Qn], where each QoS value maps to a set of KPIs corresponding to the quality parameters) to the L1 resources via the QoS array. For example, the QoS array can be mapped to one or more KPIs, as follows: Q1 "Latency Mode" refers to the maximum allowed latency limit when processing workloads, which is useful for URLLC; Q2 "Throughput Mode" refers to the minimum user throughput, which is useful for eMBB; Q3 "Reliability Mode" refers to the minimum reliability (calculated in bit error rate (BER) (KPI)), which is useful for mission-critical traffic, such as remote surgery; Q4 "Connectivity Mode" refers to the minimum number of end users per 5G-NR cell, which is useful for mMTC traffic. In at least one embodiment, call operation 310 can be performed to determine several different QoS parameters that the L1 resources can support (e.g., how many 5G-NR cells the resources in L1 can support while meeting latency requirements, and how many 5G-NR cells can be supported simultaneously to meet throughput requirements). In at least one embodiment, other values can be input into the QoS array, such as the number of cells, throughput per cell, number of end users per cell, or combinations of other relevant factors used to process cell workloads.
[0086] In at least one embodiment, the application using the API may provide additional input parameters, such as a maximum cell array (e.g., pointers to an array of integers) corresponding to the maximum number of 5G-NR cells that need to be supported for a specific quality parameter and / or a tier array (e.g., pointers to an array of integers) corresponding to tiers of 5G-NR cells and services with higher or lower priority. In at least one embodiment, the maximum number of 5G-NR cells requested for support, or the cell tiers, or the tiers or workloads, are used by one or more APIs to schedule and process one or more workloads corresponding to one or more 5G-NR cells.
[0087] In at least one embodiment, at response operation 315, the application (e.g., via an API) receives a response from L1 indicating whether L1 can acknowledge the workload to support 5G-NR cells based on quality requirements. In at least one embodiment, based on the response from L1, L2+ can adjust its scheduling strategy; for example, applications in L2+ can schedule for a maximum number of cells less than or equal to the maximum number of cells in L1 that meet a certain quality parameter. In at least one embodiment, response operation 315 includes L1 responding with a simple "1" or "0" to indicate acknowledgment or rejection (acknowledgment may also include allow, enable, accept start, and execute; rejection may include denial, stop, prevent, or block). In at least one embodiment, response operation 315 includes L1 responding with acknowledgment and / or rejection, and includes the maximum number of cells that can be supported while meeting one or more quality parameters (e.g., QoS corresponding to a network slice).
[0088] In at least one embodiment, at scheduling operation 320, one or more processors or systems executing the application may provide the maximum number of cells to the scheduler, allowing the scheduler to make scheduling decisions based on the maximum number of cells. For example, the API may provide the maximum number of 5G-NR cells that it can support while meeting quality thresholds to an L2+ application or hardware device (e.g., SMO) responsible for processing L1 scheduling workloads. In at least one embodiment, scheduling operation 320 is optional, or may be performed prior to scheduling operation 320, such that scheduling is not based on the maximum number of available cells.
[0089] In at least one embodiment, after response operation 315 or scheduling operation 320, one or more processors or systems executing the application may repeat process 300 or portions thereof, for example, for a new application requesting the use of the hardware accelerator in L1.

[0090] Figure 4 This is a process flowchart according to at least one embodiment, including more details on processing the workload of the network protocol stack. Figure 2 As indicated by the "B" mark in the document, Figure 4 Provides integration into Process 200 or with Figure 2 Further details regarding the parallel execution of process 400. In at least one embodiment, one or more processors or systems execute process 400 by executing an API. In at least one embodiment, process 400 is executed by one or more circuits to process the O-RAN network protocol stack (e.g., such as...). Figure 1 The 5G-NR workload of the network protocol stack 100 shown.
[0091] In at least one embodiment, part or all of process 400 (or any other process described herein, or variations and / or combinations thereof) is executed under the control of one or more computer systems configured with computer-executable instructions and is implemented by hardware, software, or a combination thereof as code (e.g., computer-executable instructions, one or more computer programs, or one or more application programs) that executes jointly on one or more processors. In at least one embodiment, at least some of the computer-readable instructions available for executing process 400 are not stored using merely transient signals (e.g., propagating transient electrical or electromagnetic transmissions). In at least one embodiment, process 400 is executed at least partially on computer systems (such as those described elsewhere in this disclosure). In at least one embodiment, process 400 is executed logically (e.g., hardware, software, or a combination of hardware and software). In at least one embodiment, process 400 may begin with a call operation 410 and proceed to a mapping cell operation 415 (e.g., as...). Figure 2 (Part of mapping operation 210 in process 200).
[0092] In at least one embodiment, at operation 410, where an API is called to map cell workloads, one or more processor or system calls to the API are executed to map a specific 5G-NR cell (e.g., cell ID) to a specific resource in L1. In at least one embodiment, "to map" refers to mapping, allocating, or reserving L1 resources (e.g., hardware accelerators) to support or execute one or more workloads for a 5G-NR cell with a specific cell ID. In at least one embodiment, mapping refers to associating a 5G-NR cell with a specific hardware accelerator or a specific thread or computing resource in L1. For example, an API might be called to map the cell IDs of five 5G-NR cells to five different GPUs, or to map cell IDs to 10,000 different threads supported by different hardware accelerators in L1, where the mapping is based on associating a specific 5G-NR cell to meet the requirements of operation 205. Figure 2 ) or call operation 310 ( Figure 3 The quality parameters established in ) are described. In at least one embodiment, the API may be based on the quality parameters established in the determination operation 205 ( Figure 2 ) or call operation 310 ( Figure 3 The content established in ) maps the cell ID to other characteristics, such as priority, level, or combination.
[0093] In at least one embodiment, at cell mapping operation 415, one or more processors map a specific 5G-NR cell to hardware accelerator resources and respond to the application regarding whether such mapping was successful. In at least one embodiment, at map verification operation 420, one or more processors or systems providing L1 return an array with entries "1" or "0" to indicate whether the mapping was successful. In at least one embodiment, if the mapping is unsuccessful, one or more processors repeat cell mapping operation 415.
[0094] In at least one embodiment, after the verification mapping operation 420, one or more circuits may repeat process 400 or a portion thereof, for example, for a new application requesting the use of the hardware accelerator in L1. In at least one embodiment, after the verification mapping operation 420, one or more processors provide the result of process 400 to process 200 and terminate process 400.
[0095] Figure 5 This is a process flowchart according to at least one embodiment, including more details on processing the workload of the network protocol stack. Figure 2 As indicated by the "C" mark, Figure 5Further details are provided regarding what can be integrated into process 200. In at least one embodiment, process 500 is executed by one or more circuits to process the O-RAN network protocol stack (e.g., such as...). Figure 1 The 5G-NR workload of the network protocol stack 100 shown.
[0096] In at least one embodiment, part or all of process 500 (or any other process described herein, or variations and / or combinations thereof) is executed under the control of one or more computer systems configured with computer-executable instructions and is implemented by hardware, software, or a combination thereof as code (e.g., computer-executable instructions, one or more computer programs, or one or more application programs) that executes jointly on one or more processors. In at least one embodiment, at least some of the computer-readable instructions available for executing process 500 are not stored using only transient signals (e.g., propagating transient electrical or electromagnetic transmissions). In at least one embodiment, the non-transient computer-readable medium does not necessarily include non-transient data storage circuitry (e.g., buffers, caches, and queues) within a transceiver of transient signals. In at least one embodiment, process 500 is executed at least partially on a computer system (such as those described elsewhere in this disclosure). In at least one embodiment, process 500 is executed logically (e.g., hardware, software, or a combination of hardware and software). In at least one embodiment, process 500 may begin with a call operation 510 and proceed to a response operation 515.
[0097] At operation 510, which involves calling a selection API, one or more processors or system calls of the application are executed to select a processing algorithm for a workload, wherein the workload is associated with supporting one or more 5G-NR cells, such as those established in process 200 or process 400. In at least one embodiment, one or more processors providing L1 can access a library including different processing algorithms (e.g., one or more technologies) to process a specific workload to meet quality parameters, such as a low-latency algorithm for processing a workload with low-latency quality parameters, or a high-throughput algorithm designed to process a workload to meet high-throughput quality parameters. In at least one embodiment, the API has quality parameters as input, and based on the quality parameters, the API searches a library of algorithms optimized for a specific workload that simultaneously meet the quality parameters. At selection operation 515, one or more processors or systems execute a selection of a processing algorithm based on a call to selection operation 510. In at least one embodiment, the API has a quality parameter as input, and based on the quality parameter, the API searches a library of algorithms optimized for a specific workload that simultaneously satisfy the quality parameter, and the API's response causes one or more processors to select an algorithm.
[0098] In addition to the selection algorithm, in at least one embodiment, one or more processors execute an API to determine a schedule or order for processing workloads (e.g., sequentially or in parallel to meet quality parameters or priorities). For example, if heterogeneous workloads are provided for processing by one or more cells, the API can cause one or more processors to schedule processing to prioritize groups with higher priorities than lower priorities in sequential processing (e.g., based on rank input received from another API). In at least one embodiment, for homogeneous workloads (e.g., without ranks or priorities), another scheduling strategy can be to group workloads based on the direction of data flow (e.g., downlink or uplink) and prioritize the processing of time-sensitive downlink operations over time-insensitive uplink operations.
[0099] In at least one embodiment, at query success operation 520, one or more processors or systems respond to the application via the L2-L1 interface, indicating whether the selection of an algorithm and / or scheduling for priority or rank was successful. For example, after L1 selects an algorithm and determines whether the workload is processed sequentially or in parallel, L1 may respond with "1" to indicate that the workload is being processed and the algorithm selection was successful. In at least one embodiment, if one or more processors determine that the selection was unsuccessful, the one or more processors may call the API again.
[0100] In at least one embodiment, after a successful query operation 520, one or more circuits may repeat process 500 or a portion thereof, for example, for a new application requesting the use of the hardware accelerator in L1. In at least one embodiment, after a successful query operation 520, one or more processors provide the result of process 500 to process 200 and terminate process 400.
[0101] Figure 6 A schematic block diagram of a process 600 for processing workloads according to at least one embodiment is shown. Figure 6 Including application 105 (e.g., from Figure 1 ), L2-L1 interface 115 (e.g., from Figure 1 ), first layer (L1) 605 and hardware accelerator 610 (e.g., from Figure 1The second processor 130). In at least one embodiment, one or more processors or systems execute process 600 when supporting 5G-NR services for multiple 5G-NR cells. In at least one embodiment, application 105 queries L1 605 via L2-L1 interface 115 to determine how many 5G-NR cells resources (e.g., hardware accelerators) in L1 605 can support, as indicated by QoS query 615. In at least one embodiment, the QoS query is based on quality parameters (e.g., latency corresponding to URLLC) and a set of KPIs for satisfying those quality parameters. In response to QoS query 615, L1 605 can respond to application 105 to acknowledge or reject the request to support the 5G-NR workload in QoS response / acknowledgment 620, and it can also respond with the number of cells that can be supported and satisfy the quality parameters (e.g., such as...). Figure 2 and Figure 3 (As discussed in the document). In at least one embodiment, if the request is acknowledged, application 105 communicates via the L2-L1 interface (e.g., using...). Figure 3 , Figure 4 and Figure 5 The L1 605 provides configuration parameters 625 to the L1 605 via the publicly available API. For example, application 105 provides a cell ID for a 5G-NR cell that will be supported by one or more hardware accelerators in the L1 605. After providing a configuration response 635, the L1 605 can assign a specific cell to a thread or hardware accelerator, as shown in operation allocation resource 630. For example, through interface L2-L1, the L1 can reserve a specific hardware accelerator 610 (e.g., 5 GPUs or 1 FPGA) to handle the workload to support the 5G-NR cell.
[0102] In at least one embodiment, L1 605 responds to application 105 with an acknowledgment response 635 via L2-L1 interface 115, for example, whether the mapping from cell ID to specific hardware accelerator 610 was successful. In at least one embodiment, after configuring response 635, application 105 can provide workloads and enqueue (e.g., prepare) workloads using workload enqueue 640. Next, in at least one embodiment, L1 605 selects, as... Figure 2 Algorithm 645 disclosed herein is used to process workloads such that the optimal algorithm is selected based at least on the quality parameters of the workload. For example, if the workloads have similar or identical QoS requirements, L1 can use libraries and drivers to enable the hardware accelerator to select homogeneous workload processing, or L1 can use libraries and drivers to enable the hardware accelerator to select heterogeneous processing algorithms (e.g., one algorithm for processing workloads with low latency QoS requirements and another algorithm for processing different workloads with high throughput requirements).
[0103] In at least one embodiment, L1 605 can select a scheduling mode 650, such as scheduling workload processing sequentially (e.g., processing workload A first, and then processing workload B). In at least one embodiment, based on the selected scheduling mode 650, L1 605 schedules workload processing 655 as sequential 660 (e.g., processing sequential workloads on an FPGA), parallel 665 (e.g., processing different workloads in parallel using a GPU or parallel processor), or a combination of sequential and parallel processing, such that the workload is processed to meet QoS requirements and is processed on time. In at least one embodiment, application 105 can query the status of workload 670 being processed in L1 605 and receive a response regarding the workload processing status 675 (e.g., workload processing has completed, is still in progress, has ended, or there is an error).

[0236] In at least one embodiment, conventional ADAS systems may be prone to generating false alarms, 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 determine whether a safe situation truly exists and take appropriate action. In at least one embodiment, in the event of conflicting results, vehicle 1000 itself decides whether to follow the result of the main computer or the auxiliary computer (e.g., the first controller 1036 or the second controller 1036).

[0238] In at least one embodiment, the supervisory MCU may be configured to run a neural network trained and configured to determine, at least in part, the conditions under which the auxiliary computer provides a false alarm based on outputs from a host computer and an auxiliary computer. In at least one embodiment, the neural network in the supervisory MCU may learn when the outputs of the auxiliary computer can be trusted and when they cannot. For example, in at least one embodiment, when the auxiliary computer is a RADAR-based FCW system, the neural network in the supervisory MCU may learn when the FCW system recognizes a metallic object that is not actually dangerous, such as a drain grating or manhole cover that would trigger an alarm. In at least one embodiment, when the auxiliary computer is a camera-based LDW system, the neural network in the supervisory MCU may learn to override the LDW when a cyclist or pedestrian is present and lane departure is actually the safest operation.

In at least one embodiment, the supervisory MCU may include and / or be included as a component of one or more SoC 1004s.
[0239] In at least one embodiment, the ADAS system 1038 may include an auxiliary computer that performs ADAS functions using conventional computer vision rules. In at least one embodiment, the auxiliary computer may use classic computer vision rules (if-then), and the presence of a neural network in the supervisory MCU can improve reliability, security, and performance. For example, in at least one embodiment, diverse implementations and intentional non-identity make the entire system more fault-tolerant, especially for failures caused by software (or software-hardware interface) functionality. For example, in at least one embodiment, if a software vulnerability or bug exists in the software running on the host computer, and different software code running on the auxiliary computer provides consistent overall results, the supervisory MCU can more confidently assume that the overall result is correct and that the vulnerability in the software or hardware on the host computer will not lead to a significant error.
[0240] In at least one embodiment, the output of the ADAS system 1038 can be input to the perception module and / or the dynamic driving task module of the host computer. For example, in at least one embodiment, if the ADAS system 1038 indicates a forward collision warning due to an object directly ahead, the perception block can use this information when identifying the object. In at least one embodiment, as described herein, the assistance computer can have its own neural network trained to reduce the risk of false alarms.

In one embodiment, GPUs 1510-1513 are part of a first processor 125 or a second processor 130, wherein GPUs 1510-1513 can perform... Figures 3 to 6 The processes and procedures disclosed herein. In one embodiment, the high-speed links 1540-1543 support communication throughput of 4GB / s, 30GB / s, 80GB / s, or higher. Various interconnect protocols can be used, including but not limited to PCIe 4.0 or 5.0 and NVLink 2.0.
[0271] Furthermore, in one embodiment, two or more GPUs 1510-1513 are interconnected via high-speed links 1529-1530, which may use the same or different protocols / links as those used for high-speed links 1540-1543. Similarly, two or more multi-core processors 1505-1506 may be connected via high-speed link 1528, which may be a symmetric multiprocessor (SMP) bus operating at speeds of 20GB / s, 30GB / s, 120GB / s, or higher. Alternatively, the same protocol / link may be used (e.g., via a common interconnect structure). Figure 15A This shows all communication between the various system components.
[0272] In one embodiment, each multi-core processor 1505-1506 is communicatively coupled to processor memories 1501-1502 via memory interconnects 1526-1527, and each GPU 1510-1513 is communicatively coupled to GPU memories 1520-1523 via GPU memory interconnects 1550-1553. Memory interconnects 1526-1527 and 1550-1553 may utilize the same or different memory access technologies. By way of example and not limitation, processor memories 1501-1502 and GPU memories 1520-1523 may be volatile memories, 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 may be non-volatile memories, such as 3D XPoint or Nano-RAM. In one embodiment, some portions of processor memories 1501-1502 may be volatile memory, while other portions may be non-volatile memory (e.g., using a two-level memory (2LM) hierarchy).
[0273] As described in this article, although the various processors 1505-1506 and GPUs 1510-1513 can be physically coupled to specific memories 1501-1502 and 1520-1523 respectively, a unified memory architecture can be implemented, in which the same virtual system address space (also known as the “effective address” space) is distributed across the various physical memories. For example, processor memories 1501-1502 can each include 64 GB of system memory address space, and GPU memories 1520-1523 can each include 32 GB of system memory address space (resulting in a total addressable memory size of 256 GB in this example).
[0274] Figure 15BAdditional details are shown regarding the interconnection between a multi-core processor 1507 and a graphics acceleration module 1546 according to an exemplary embodiment. The graphics acceleration module 1546 may include one or more GPU chips integrated on a line card coupled to the processor 1507 via a high-speed link 1540. Alternatively, the graphics acceleration module 1546 may be integrated on the same package or chip as the processor 1507.
[0275] In at least one embodiment, the processor 1507 shown includes multiple cores 1560A-1560D, each core having a translation back buffer 1561A-1561D and one or more caches 1562A-1562D. In at least one embodiment, cores 1560A-1560D may include various other components (not shown) for executing instructions and processing data. Caches 1562A-1562D may include level 1 (L1) and level 2 (L2) caches. Furthermore, one or more shared caches 1556 may be included in caches 1562A-1562D and shared by the respective groups of cores 1560A-1560D. For example, one embodiment of the processor 1507 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 1507 and the graphics acceleration module 1546 are connected to a system memory 1518, which may include... Figure 15A The processor memory 1501-1502 in the memory.
[0276] Consistency of data and instructions stored in the various caches 1562A-1562D, 1556 and system memory 1514 is maintained via inter-core communication through the consistency bus 1564. For example, each cache may have associated cache consistency logic / circuit to communicate via the consistency bus 1564 in response to the detection of a read or write to a specific cache line. In one implementation, a cache snooping protocol is implemented via the consistency bus 1564 to snoop on cache accesses.
[0277] In one embodiment, proxy circuitry 1525 communicatively couples graphics acceleration module 1546 to coherence bus 1564, thereby allowing graphics acceleration module 1546 to participate in cache coherence protocols as a peer of cores 1560A-1560D. Specifically, interface 1535 provides connectivity to proxy circuitry 1525 via high-speed link 1540 (e.g., PCIe bus, NVLink, etc.), and interface 1537 connects graphics acceleration module 1546 to link 1540.
[0278] In one implementation, the accelerator integrated circuit 1536 represents multiple graphics processing engines 1531, 1532, N of the graphics acceleration module 1546, providing cache management, memory access, context management, and interrupt management services. The graphics processing engines 1531, 1532, N may each include a separate graphics processing unit (GPU). Optionally, the graphics processing engines 1531, 1532, N may selectively include different types of graphics processing engines within the GPU, such as graphics execution units, media processing engines (e.g., video encoders / decoders), samplers, and blit engines. In at least one embodiment, the graphics acceleration module 1546 may be a GPU having multiple graphics processing engines 1531-1532, N, or the graphics processing engines 1531-1532, N may be individual GPUs integrated on a general-purpose package, line card, or chip.
[0279] In one embodiment, the accelerator integrated circuit 1536 includes a memory management unit (MMU) 1539 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 1514. The MMU 1539 may also include a translation back buffer (“TLB”) (not shown) for caching virtual / effective-to-physical / real address translations. In one implementation, cache 1538 may store commands and data for effective access by graphics processing engines 1531-1532,N. In one embodiment, data stored in cache 1538 and graphics memories 1533-1534,M is kept consistent with core caches 1562A-1562D, 1556 and system memory 1514. As previously mentioned, this task can be accomplished via proxy circuitry 1525 representing cache 1538 and graphics memory 1533-1534, M (e.g., sending updates related to the modification / access of cache lines on processor caches 1562A-1562D, 1556 to cache 1538 and receiving updates from cache 1538).
[0280] A set of registers 1545 stores the context data of the threads executed by graphics processing engines 1531-1532, N, and context management circuitry 1548 manages the thread context. For example, context management circuitry 1548 can perform save and restore operations to save and restore the context of individual threads during context switching (e.g., saving the first thread and storing the second thread so that the second thread can be executed by the graphics processing engine). For example, during context switching, context management circuitry 1548 can store the current register value into a designated area in memory (e.g., identified by the context pointer). The register value can then be restored when returning to the context. In one embodiment, interrupt management circuitry 1547 receives and processes interrupts received from system devices.
[0281] In one implementation, MMU 1539 translates virtual / effective addresses from graphics processing engine 1531 into real / physical addresses in system memory 1514. One embodiment of accelerator integrated circuit 1536 supports multiple (e.g., 4, 8, 16) graphics accelerator modules 1546 and / or other accelerator devices. Graphics accelerator module 1546 may be dedicated to a single application executing on processor 1507, or may be shared among multiple applications. In one embodiment, a virtualized graphics execution environment is presented, where the resources of graphics processing engines 1531-1532, N are shared with multiple applications or virtual machines (VMs). In at least one embodiment, resources may be subdivided into “slices” based on processing requirements and priorities associated with VMs and / or applications, which are allocated to different VMs and / or applications.
[0282] In at least one embodiment, the accelerator integrated circuit 1536 acts as a bridge to the system of the graphics acceleration module 1546, providing address translation and system memory caching services. Additionally, in at least one embodiment, the accelerator integrated circuit 1536 can provide virtualization facilities for the host processor to manage the virtualization, interrupt, and memory management of the graphics processing engines 1531-1532.
[0283] Because the hardware resources of graphics processing engines 1531-1532, N are explicitly mapped to the actual address space seen by the host processor 1507, any host processor can directly address these resources using valid address values. In one embodiment, one function of the accelerator integrated circuit 1536 is to physically separate the graphics processing engines 1531-1532, N, so that they appear as independent units to the system.
[0284] In at least one embodiment, one or more graphics memories 1533-1534, M are coupled to each graphics processing engine 1531-1532, N, respectively. Graphics memories 1533-1534, M store instructions and data, which are processed by each graphics processing engine 1531-1532, N. Graphics memories 1533-1534, M may be volatile memories, such as DRAM (including stacked DRAM), GDDR memory (e.g., GDDR5, GDDR6), or HBM, and / or may be non-volatile memories, such as 3D XPoint or Nano-RAM.
[0285] In one embodiment, to reduce data traffic on link 1540, a biasing technique can be used to ensure that the data stored in graphics memories 1533-1534, M is the data most frequently used by graphics processing engines 1531-1532, N, and preferably not used (or at least infrequently used) by cores 1560A-1560D. Similarly, in at least one embodiment, the biasing mechanism attempts to keep the data needed by the cores (and preferably not graphics processing engines 1531-1532, N) in the core caches 1562A-1562D, 1556 and system memory 1514.
[0286] Figure 15C Another exemplary embodiment is shown, in which the accelerator integrated circuit 1536 is integrated within the processor 1507. In this embodiment, graphics processing engines 1531-1532, N communicate directly with the accelerator integrated circuit 1536 via a high-speed link 1540 through interfaces 1537 and 1535 (which can also utilize any form of bus or interface protocol). The accelerator integrated circuit 1536 can perform operations related to... Figure 15B The operations described are the same. However, due to its close proximity to the coherence bus 1564 and caches 1562A-1562D, 1556, it may have higher throughput. 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 may include a programming model controlled by accelerator integrated circuit 1536 and a programming model controlled by graphics acceleration module 1546.
[0287] In at least one embodiment, graphics processing engines 1531-1532, N are dedicated to a single application or process within a single operating system. In at least one embodiment, a single application can funnel requests from other applications to graphics processing engines 1531-1532, N, thereby providing virtualization within a VM / partition.
[0288] In at least one embodiment, graphics processing engines 1531-1532, N can be shared by multiple VM / application partitions. In at least one embodiment, the shared model can use a hypervisor to virtualize graphics processing engines 1531-1532, 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 1531-1532, N. In at least one embodiment, the operating system can virtualize graphics processing engines 1531-1532, N to provide access to each process or application.
[0289] In at least one embodiment, the graphics acceleration module 1546 or the respective graphics processing engines 1531-1532, N uses a process handle to select a process element. In at least one embodiment, the process element is stored in system memory 1514 and can be addressed using the effective address to physical address translation techniques described herein. In at least one embodiment, the process handle may be an implementation-specific value provided to the host process when registering its context with the graphics processing engines 1531-1532, N (i.e., invoking 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 may be the offset of the process element in the process element linked list.
[0290] Figure 15D An exemplary accelerator integration slice 1590 is shown. As used herein, a “slice” includes a designated portion of the processing resources of the accelerator integrated circuit 1536. The application’s effective address space 1582 in system memory 1518 stores process element 1583. In one embodiment, process element 1583 is stored in response to a GPU call 1581 from an application 1580 executing on processor 1507. Process element 1583 includes the process state of the corresponding application 1580. A job descriptor (WD) 1584 included in process element 1583 may be a single job requested by the application, or may include a pointer to a job queue. In at least one embodiment, WD 1584 is a pointer to a job request queue in the application’s address space 1582.
[0291] The graphics acceleration module 1546 and / or the various graphics processing engines 1531-1532, N can be shared by all processes or a subset of processes in the system. In at least one embodiment, infrastructure may be included for setting process states and sending WD 1584 to the graphics acceleration module 1546 to begin operations in a virtualized environment.
[0292] 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 the graphics acceleration module 1546 or an individual graphics processing engine 1531. When the graphics acceleration module 1546 is owned by a single process, the hypervisor initializes the accelerator integrated circuit 1536 for the owned partition; when the graphics acceleration module 1546 is assigned, the operating system initializes the accelerator integrated circuit 1536 for the owned process.
[0293] In operation, the WD fetch unit 1591 in the accelerator integrated slice 1590 fetches the next WD 1584, which includes instructions for the work to be performed by one or more graphics processing engines of the graphics acceleration module 1546. Data from the WD 1584 can be stored in register 1545 and used by the MMU 1539, interrupt management circuitry 1547, and / or context management circuitry 1548, as shown. For example, one embodiment of the MMU 1539 includes segment / page roaming circuitry for accessing segment / page tables 1586 within the OS virtual address space 1585. The interrupt management circuitry 1547 can handle interrupt events 1592 received from the graphics acceleration module 1546. When performing graphics operations, the effective address 1593 generated by the graphics processing engines 1531-1532,N is translated into a real address by the MMU 1539.
[0294] In one embodiment, for each graphics processing engine 1531-1532, N and / or graphics acceleration module 1546, the same set of registers 1545 is copied, and said registers 1545 can be initialized by a hypervisor or operating system. Each of these copied registers can be included in the accelerator integration slice 1590. Exemplary registers that can be initialized by a hypervisor are shown in Table 1.
[0295]
[0296] Table 2 shows exemplary registers that can be initialized by the operating system.
[0297]
[0298] In one embodiment, each WD 1584 is specific to a particular graphics acceleration module 1546 and / or graphics processing engine 1531-1532,N. It includes all the information required for the graphics processing engine 1531-1532,N to complete its work, or it may be a pointer to a memory location where the application has set up a command queue for the work to be completed.
[0299] Figure 15EAdditional details of an exemplary embodiment of the shared model are shown. This embodiment includes a hypervisor real address space 1598, in which a list of process elements 1599 is stored. The hypervisor real address space 1598 can be accessed via a hypervisor 1596, which virtualizes the graphics acceleration module engine for operating system 1595.
[0300] In at least one embodiment, the shared programming model allows all processes or subsets of processes from all partitions or subsets of partitions in the system to use the graphics acceleration module 1546. In at least one embodiment, there are two programming models, wherein the graphics acceleration module 1546 is shared by multiple processes and partitions, time-slice sharing, and graphics-oriented sharing.
[0301] In this model, the hypervisor 1596 owns the graphics acceleration module 1546 and makes its functionality available to all operating systems 1595. For the graphics acceleration module 1546 to support virtualization through the hypervisor 1596, the graphics acceleration module 1546 may comply with the following: (1) the job requests of the application must be autonomous (i.e., no state needs to be maintained between jobs), or the graphics acceleration module 1546 must provide a context saving and restoring mechanism; (2) the graphics acceleration module 1546 guarantees that the job requests of the application are completed within a specified amount of time, including any conversion errors, or the graphics acceleration module 1546 provides the ability to preempt job processing; and (3) when operating in a directed shared programming model, fairness between the processes of the graphics acceleration module 1546 must be ensured.
[0302] In at least one embodiment, application 1580 needs to make a system call to operating system 1595 using graphics acceleration module 1546 type, working descriptor (WD), authority mask register (AMR) value, and context save / restore region pointer (CSRP). In at least one embodiment, the graphics acceleration module 1546 type describes the target acceleration function for the system call. In at least one embodiment, the graphics acceleration module 1546 type can be a system-specific value. In at least one embodiment, the WD is specifically formatted for graphics acceleration module 1546 and can take the form of graphics acceleration module 1546 commands, valid address pointers to user-defined structures, valid address pointers to command queues, or any other data structure describing the work to be performed by graphics acceleration module 1546. 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 the application that sets the AMR. In at least one embodiment, if the implementation of accelerator integrated circuit 1536 and graphics acceleration module 1546 does not support the User Authority Mask Overwrite Register (UAMOR), the operating system can apply the current UAMOR value to the AMR value before passing the AMR in the hypervisor call. In at least one embodiment, the hypervisor 1596 may selectively apply the Current Privilege Mask Overwrite Register (AMOR) value before placing the AMR into process element 1583. In at least one embodiment, the CSRP is one of registers 1545 that includes the effective address of a region in the application's address space 1582 for the graphics acceleration module 1546 to save and restore context state. This pointer is optional if saving state between jobs is not required or when a job is preempted. In at least one embodiment, the context save / restore region may be fixed system memory.
[0303] Upon receiving a system call, the operating system 1595 can verify that the application 1580 has been registered and granted permission to use the graphics acceleration module 1546. Then, the operating system 1595 uses the information shown in Table 3 to invoke the hypervisor 1596.
[0304]
[0305] Upon receiving a hypervisor call, hypervisor 1596 verifies that operating system 1595 has been registered and granted permission to use graphics acceleration module 1546. Then, hypervisor 1596 adds process element 1583 to the linked list of process elements of the corresponding graphics acceleration module 1546 type. The process element may include the information shown in Table 4.
[0306]
[0307] In at least one embodiment, the hypervisor initializes multiple accelerator integration slice 1590 registers 1545.
[0308] like Figure 15F As shown, in at least one embodiment, a unified memory is used, which is addressable via a common virtual memory address space for accessing physical processor memories 1501-1502 and GPU memories 1520-1523. In this implementation, operations performed on GPUs 1510-1513 utilize the same virtual / effective memory address space to access processor memories 1501-1502 and vice versa, thereby simplifying programmability. In one embodiment, a first portion of the virtual / effective address space is allocated to processor memory 1501, a second portion to second processor memory 1502, a third portion to GPU memory 1520, and so on. In at least one embodiment, the entire virtual / effective memory space (sometimes referred to as the effective address space) is thus distributed across each of processor memories 1501-1502 and GPU memories 1520-1523, thereby allowing any processor or GPU to access that memory using a virtual address mapped to any physical memory.
[0309] In one embodiment, the bias / coherence management circuitry 1594A-1594E within one or more MMUs 1539A-1539E ensures cache coherence between the caches of one or more host processors (e.g., 1505) and the GPUs 1510-1513, and implements biasing techniques to indicate the physical memory in which certain types of data should be stored. In at least one embodiment, although in Figure 15F Several instances of bias / coherence management circuitry 1594A-1594E are shown, but bias / coherence circuitry can be implemented within the MMU of one or more host processors 1505 and / or within the accelerator integrated circuit 1536.
[0310] One embodiment allows GPU-attached memories 1520-1523 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-attached memories 1520-1523 as system memory without the heavy overhead of cache coherence provides a favorable operating environment for GPU offloading. This arrangement allows the host processor 1505 to software-set operands and access computation results without the overhead of conventional I / O DMA data copying. Such conventional copying includes 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-attached memories 1520-1523 without cache coherence overhead can be critical for the execution time of offloaded computations. For example, in cases with high streaming write traffic to memory, cache coherence overhead can significantly reduce the effective write bandwidth seen by GPUs 1510-1513. In at least one embodiment, the efficiency of operand setup, the efficiency of result access, and the efficiency of GPU computation may play a role in determining the effectiveness of GPU offloading.
[0311] 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 may be a page-granular structure (e.g., controlled at the memory page level) comprising 1 or 2 bits of memory pages attached to each GPU. In at least one embodiment, with or without a bias cache (e.g., for caching frequently / recently used entries in the bias table) in GPUs 1510-1513, the bias table can be implemented across the stolen memory range of one or more GPU-attached memories 1520-1523. Alternatively, the entire bias table can be maintained within the GPU.
[0312] In at least one embodiment, prior to actual access to GPU memory, the bias table entry associated with each access to GPU-attached memory 1520-1523 is accessed, causing the following operations: First, a local request from GPUs 1510-1513 to find its page in the GPU bias is directly forwarded to the corresponding GPU memory 1520-1523. A local request from the GPU to find its page in the host bias is forwarded to processor 1505 (e.g., via the high-speed link described above). In one embodiment, a request from processor 1505 to find the requested page in the host processor bias completes a request similar to a normal memory read. Alternatively, requests to GPU bias pages can be forwarded to GPUs 1510-1513. In at least one embodiment, if the GPU is not currently using the page, the GPU may subsequently migrate the page to the host processor bias. In at least one embodiment, the page bias state can be changed through software-based mechanisms, hardware-assisted software mechanisms, or, in limited cases, purely hardware-based mechanisms.
[0313] One mechanism for changing the bias state employs an API call (e.g., OpenCL), which subsequently invokes the GPU's device driver. The device driver then sends a message (or enqueues a command descriptor) to the GPU, instructing the GPU to change the bias state and, in some migrations, performs a cache refresh operation on the host. In at least one embodiment, the cache refresh operation is used for migrations from the host processor 1505 bias to the GPU bias, but not for the reverse migration.
[0314] In one embodiment, cache coherence is maintained by temporarily rendering GPU bias pages that the host processor 1505 cannot cache. To access these pages, the processor 1505 may request access from the GPU 1510, which may or may not grant access immediately. Therefore, to reduce communication between the processor 1505 and the GPU 1510, it is beneficial to ensure that the GPU bias pages are pages needed by the GPU, not those needed by the host processor 1505, and vice versa.
