Description

Technical Field

[0001] The present invention relates to the field of computer technology, and more specifically, to a computing system, a method executed by the computing system, and a storage medium. Background Art

[0002] In the prior art, AI chip solutions for detection and computing tasks are mainly divided into two categories. One is general-purpose processors, such as CPU (Central Processing Unit), FPGA (Field Programmable Gate Array), GPU (Graphics Processing Unit), etc.; the other is acceleration processors specifically for artificial neural networks, such as Google's TPU (Tensor Processing Units). These chips all belong to the von Neumann architecture, where computing and storage are separated, and the two work together to complete data access and computing. However, since the design of the processor is mainly to improve computing speed, and storage is more focused on capacity improvement and cost optimization, there is a performance mismatch between "storage" and "computing", which leads to problems such as low memory access bandwidth, extended latency, and high power consumption, which are commonly referred to as the "storage wall" and "power consumption wall". The denser the memory access, the more serious the "wall" problem, and the more difficult it is to improve computing power.

[0003] As a new computing architecture, storage-computing integration fully integrates storage and computing, effectively overcomes the bottleneck of the von Neumann architecture, and can greatly improve computing power.

[0036] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, the same elements are represented by the same or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0037] The specific implementation of the present invention is further described in detail below in conjunction with the drawings and examples.

[0038] As mentioned above, general-purpose CPUs and GPUs have advantages in data-intensive general-purpose computing related to artificial intelligence, but general-purpose computing is difficult to cope with complex and changeable computing operators. In-memory computing generally adopts the AISC (application-specific integrated circuit) mode, which supports very limited operator types, and has poor programming flexibility and versatility, and cannot flexibly match the current development speed of neural network models.

[0039] In response to the above technical problems, the basic idea of ​​the present application is to combine a general-purpose processor and a tensor processor, describe the instruction type in the computing instruction to distinguish between tensor operation instructions and general-purpose operation instructions, send the tensor operation instructions to the tensor processor to perform in-memory calculations or non-memory calculations, and send the general-purpose operation instructions to the general-purpose processor to perform general-purpose calculations. This can not only ensure versatility but also improve computing power, and support complex and changeable computing operators in neural networks.

[0040] Figure 1 FIG. 1 is a schematic diagram showing a structure of a computing system provided according to an embodiment of the present application. Figure 1 As shown, the computing system 100 includes a general purpose processor 110 and a tensor processor 120 .

[0041] The general purpose processor 110 includes an instruction scheduling module 111 and at least one computing unit CU.

[0042] The instruction scheduling module 111 is used to identify a computing instruction, and when the computing instruction is identified as a tensor operation instruction, send the tensor operation instruction to the tensor processor 120 .

[0043] In this embodiment, the computing instruction includes an operation code and an operation field, wherein the operation code includes the instruction type and operation code of the computing instruction, and the operation field includes at least a source address and a target address of data to be operated.

[0044] Specifically, the instruction type is used to describe the type of operation involved in the computing instruction, and the instruction type includes tensor operation, vector operation, scalar operation and transcendental function operation. The operation code is used to describe the operation to be completed by the computing instruction (for example, addition, subtraction, multiplication, division, special function, etc.), which specifically describes the nature and function of the operation.

[0045] The operation domain includes the source address and target address of the data to be operated. The source address and the target address can be a memory address or a register address (i.e., a register number). The memory or register can be an off-chip memory. Of course, in practical applications, it can also be an on-chip memory for storing data. The data can specifically be 1 data value (scalar) or n-dimensional data (vector or tensor), where n is an integer greater than or equal to 1. For example, when n=1, it is 1-dimensional data, i.e., a vector; when n=2, it is 2-dimensional data, i.e., a matrix; when n=3 or more, it is a multi-dimensional tensor.

[0046] In this embodiment, the opcode may be the part of the instruction or field (usually represented by a code) specified in the computer program to perform the operation, which is an instruction sequence number used to inform the device executing the instruction which specific instruction needs to be executed. The operation domain may be the source of all data required to execute the corresponding instruction, such as the corresponding address, etc. All data required to execute the corresponding instruction include the data to be calculated and the corresponding instruction processing method, etc. For a calculation instruction, it must include an opcode and an operation domain, wherein the operation domain at least includes the source address and the target address of the data to be calculated. It should be understood that those skilled in the art can set the instruction format of the calculation instruction and the opcode and operation domain contained therein as needed, and the present disclosure does not limit this.

[0047] In a preferred embodiment, the source address of the data to be operated may be the starting address of the storage space where the data to be operated is located, and the general processor 110 or the tensor processor 120 may obtain instructions and data through a data input and output unit, which may be one or more data I / O interfaces or I / O pins. Further, the general processor 110 or the tensor processor 120 may determine the data to be operated according to the source address of the data to be operated, and obtain the data to be operated. Of course, in other embodiments, the general processor 110 or the tensor processor 120 may also determine the data required for the operation according to the operation code of the calculation instruction.

[0048] In one possible implementation, the instruction format of the calculation instruction may be as shown in the following table:

[0049] Table 1:

[0050]

[0051] Wherein, type, opcode is the operation code of the computing instruction, dst, scr is the operation domain of the computing instruction, and dst is the target address. src is the source address of the data to be operated. When there are multiple data to be operated, src may include multiple data to be operated src0, src1, ..., srcn, and dst may also include multiple target addresses dst0, dst1, ..., dstn, which is not limited in the present disclosure.

[0052] In some specific embodiments, the scalar operation and vector operation in the general operation instruction may be shown in the following table:

[0053] Table 2:

[0054]

[0055] When executing the operation instructions shown in the above table, the general processor 110 reads Num1 floating-point data or integer data from the address specified in the register Reg1, reads Num2 floating-point data or integer data from the address specified in the register Reg2, then performs multiplication and addition operations, and then stores the calculation results in the address space specified in the register Reg3.

[0056] In some specific embodiments, the transcendental function operation in the general operation instruction may be as shown in the following table:

[0057] Table 3:

[0058]

[0059] When executing the operation instructions shown in the above table, the general processor 110 reads Num1 data from the address specified in the register Reg1, reads Num2 data from the address specified in the register Reg2, then performs the function operation, and then stores the calculation result in the address space specified in the register Reg3.

[0060] In some specific embodiments, the tensor operation instruction may be as shown in the following table:

[0061] Table 4:

[0062]

[0063] When executing the operation instructions shown in the above table, the tensor processor 120 reads Num1 tensor data from the address specified in the register Reg1, reads Num2 weight data from the address specified in the register Reg2, and then performs a convolution operation or a multiplication and addition operation, and then stores the calculation result in the address space specified in the register Reg3.

[0064] In a preferred embodiment, if there is no information on the number of data that needs to be read in the operation domain of the operation instruction, it means that the data that needs to be read is a fixed number of data, which can be one data, a row of data, or a column of data, etc., and the embodiment of the present application does not make specific restrictions.

[0065] In this embodiment, when the instruction type in the computing instruction is a tensor operation (for example, the instruction type is Tensor), the instruction scheduling module 111 identifies the computing instruction as a tensor operation instruction; when the instruction type in the computing instruction is one of a vector operation, a scalar operation, and a transcendental function operation (for example, the instruction type is Float, INT, SUF), the instruction scheduling module 111 identifies the computing instruction as a general operation instruction. The tensor operation instruction includes at least one of a matrix multiplication operation (MM), a matrix multiplication and addition operation (MAC), and a convolution operation (Conv); the general operation instruction includes at least one of a floating-point multiplication and addition operation, an integer multiplication and addition operation, and a transcendental function operation.

[0066] The instruction scheduling module 111 is further configured to send the general operation instruction to the computing unit CU when identifying that the computing instruction is a general operation instruction; the computing unit CU is configured to perform general calculation according to the general operation instruction.

[0067] Figure 1 Two computing units CU are specifically shown as examples, and other possible computing units are omitted. Each computing unit CU includes an instruction distribution module, multiple computing cores (Kernel), a register stack, a shared L1 cache, etc. The instruction scheduling module 111 is also used to schedule the execution of computing tasks between multiple computing units CU. The general-purpose processor in this embodiment is any one of a CPU, a GPU, a DSP (Digital Signal Process, digital signal processor), and a GPGPU (General Purpose Computing on Graphics Processing Units, general-purpose graphics processor).

[0068] The computing system can be used for computing tasks such as matrix calculations, which can be executed in parallel by multiple threads. For example, before execution, these threads are divided into multiple thread blocks in the instruction scheduling module 111, and then these thread blocks are distributed to each computing unit CU (for example, a streaming multiprocessor (SM)). All threads in a thread block are usually assigned to the same computing unit for execution. At the same time, the thread block is split into thread bundles (or simply thread bundles, thread warps), for example, each thread bundle contains a fixed number (or less than this fixed number) of threads, for example, 32 threads. Multiple thread blocks can be executed in the same computing unit, or in different computing units.

[0069] In each computing unit, the instruction distribution module 112 schedules and distributes the thread bundles so that the multiple computing cores of the computing unit CU run the corresponding thread bundles. Each computing core includes an arithmetic logic unit (ALU), a floating point computing unit, etc. According to the number of computing cores in the computing unit, multiple thread bundles in a thread block can be executed simultaneously or in time-sharing. Multiple threads in each thread bundle will execute the same instruction, and the result obtained after the instruction is executed is updated to the register corresponding to each thread bundle. The instructions and data corresponding to each computing unit CU are sent to the shared cache (e.g., shared L1 cache) in the computing unit or further sent to the unified cache for read and write operations, etc.

[0070] The tensor processor 120 is used to perform in-memory calculations and / or non-in-memory calculations according to the tensor operation instructions.

[0071] In this embodiment, the tensor processor 120 includes an instruction decoding module 121 , a first computing module 122 , and a second computing module 123 .

[0072] Among them, the instruction decoding module 121 is used to parse the tensor operation instruction, generate a selection signal according to the source address of the data to be operated and obtain the data to be operated, divide the data to be operated into multiple groups of operation data, and send the operation code and multiple groups of operation data to the first computing module 122 or the second computing module 123 according to the selection signal.

[0073] In this embodiment, the instruction decoding module 121 obtains the data to be operated and generates a selection signal according to the source address of the data to be operated described in the tensor operation instruction. The data to be operated includes activation data and weight data; if the source address of the weight data is a storage-computation integrated unit, the weight data is static data, and the instruction decoding module 121 sends the operation code and multiple groups of operation data to the first calculation module 122 according to the selection signal; if the source address of the weight data is a memory, the weight data is dynamic data, and the instruction decoding module 121 sends the operation code and multiple groups of operation data to the second calculation module 123 according to the selection signal. In other embodiments, the instruction decoding module 121 can also generate a selection signal according to the operation code.

[0074] See also Figure 2 The instruction decoding module 121 includes an instruction parsing unit 1211, a data grouping unit 1212 and a control unit 1213, wherein the instruction parsing unit 1211 is used to parse the tensor operation instruction to obtain the operation code and the source address and target address of the data to be operated; the data grouping unit 1212 is used to obtain the data to be operated according to the source address of the data to be operated, and divide the data to be operated into multiple groups of operation data; the control unit 1213 is used to generate a selection signal according to the source address of the data to be operated, and send the operation code, multiple groups of data and the target address to the first computing module 122 or the second computing module 123 according to the selection signal.

[0075] In this embodiment, the operation domain may also include an execution amount. The instruction decoding module 121 is also used to obtain the execution amount and divide the data to be operated into multiple groups of operation data according to the execution amount. The execution amount is the amount of data that the first calculation module 122 or the second calculation module 123 can execute and process at one time.

[0076] In a preferred embodiment, when the operation domain does not include the execution amount, the data to be operated can be divided into multiple groups of operation data according to a preset default execution amount.

[0077] The first calculation module 122 is used to perform in-memory calculation according to the received operation code, multiple sets of operation data and target address.

[0090] In step S510 , an instruction dispatching module of a general purpose processor identifies a computing instruction.

[0091] In this embodiment, the computing instruction includes an operation code and an operation field, wherein the operation code includes the instruction type and operation code of the computing instruction, and the operation field includes at least a source address and a target address of data to be operated.

[0092] Specifically, the instruction type is used to describe the type of operation involved in the computing instruction, and the instruction type includes tensor operation, vector operation, scalar operation and transcendental function operation. The operation code is used to describe the operation to be completed by the computing instruction (for example, addition, subtraction, multiplication, division, special function, etc.), which specifically describes the nature and function of the operation.

[0093] The operation domain includes the source address and target address of the data to be operated. The source address and the target address can be a memory address or a register address (i.e., a register number). The memory or register can be an off-chip memory. Of course, in practical applications, it can also be an on-chip memory for storing data. The data can specifically be 1 data value (scalar) or n-dimensional data (vector or tensor), where n is an integer greater than or equal to 1. For example, when n=1, it is 1-dimensional data, i.e., a vector; when n=2, it is 2-dimensional data, i.e., a matrix; when n=3 or more, it is a multi-dimensional tensor.

[0094] In this embodiment, when the instruction type in the computing instruction is a tensor operation (for example, the instruction type is Tensor), the instruction scheduling module 111 identifies the computing instruction as a tensor operation instruction; when the instruction type in the computing instruction is one of a vector operation, a scalar operation, and a transcendental function operation (for example, the instruction type is Float, INT, SUF), the instruction scheduling module 111 identifies the computing instruction as a general operation instruction. The tensor operation instruction includes at least one of a matrix multiplication operation (MM), a matrix multiplication and addition operation (MAC), and a convolution operation (Conv); the general operation instruction includes at least one of a floating-point multiplication and addition operation, an integer multiplication and addition operation, and a transcendental function operation.

[0100] In this embodiment, the operation domain may also include an execution amount. The instruction decoding module 121 is also used to obtain the execution amount and divide the data to be operated into multiple groups of operation data according to the execution amount. The execution amount is the amount of data that the first calculation module 122 or the second calculation module 123 can execute and process at one time.

[0102] In step S533, a selection signal is generated according to the source address of the data to be operated, and in-memory calculation and / or non-in-memory calculation is performed according to the selection signal, the operation code, multiple groups of data and the target address.

[0103] In this embodiment, the data to be operated includes activation data and weight data; if the source address of the weight data is a storage-computation integrated unit, the weight data is static data, and the instruction decoding module 121 sends the operation code and multiple groups of operation data to the first calculation module 122 according to the selection signal; if the source address of the weight data is a memory, the weight data is dynamic data, and the instruction decoding module 121 sends the operation code and multiple groups of operation data to the second calculation module 123 according to the selection signal. In other embodiments, the instruction decoding module 121 can also generate a selection signal according to the operation code.

[0104] In step S540, when the instruction scheduling module identifies that the computing instruction is a general operation instruction, the general operation instruction is sent to the computing unit.

[0105] In step S550, the computing unit performs general computing according to the general computing instruction.

[0106] The computing method provided by the present invention combines a general-purpose processor and a tensor processor together, uses the general-purpose processor to process general-purpose calculations in a neural network, and uses the tensor processor to perform in-memory calculations or non-in-memory calculations, which can both ensure versatility and improve computing power, and support complex and changeable computing operators in neural networks.

[0107] Furthermore, the computing instructions use a unified instruction format, and one instruction can be used to drive different computing modules in the tensor processor to perform in-memory or non-memory computing, greatly reducing programming complexity.
