The first and second operands are scalar storage locations, which may include length of register, address of register, identification of register, immediate, and the like. The immediate is the number given in the immediate addressing mode instruction. The output address may be an address where data is stored, such as an output address and a write address of the processed data. The scalar calculation macro may also include other parameters related to scalar calculation, which are not limited by this disclosure.

In one possible implementation, the scalar compute macro instruction may include at least one of: a scalar addition computation macro instruction, a scalar subtraction computation macro instruction, a scalar multiplication computation macro instruction, and a scalar division computation macro instruction.

The instruction generation device comprises a device determination module, a scalar calculation macro module and a control module, wherein the device determination module is used for determining an operation device for executing the scalar calculation macro according to the received scalar calculation macro; the instruction generation module is used for calculating macro instructions and running equipment according to scalars to generate running instructions.

FIG. 2 illustrates a block diagram of a scalar compute instruction processing system according to an embodiment of the present disclosure. In one possible implementation, as shown in fig. 2, the device determining module 11 may include a first determining sub-module 111. The first determining submodule 111 is configured to determine the specified device as the running device when it is determined that the scalar calculation macro includes the identifier of the specified device and the resource of the specified device satisfies the execution condition for executing the scalar calculation macro. Wherein, the execution condition may include: the specifying means includes an instruction set corresponding to a scalar compute macro.

The identifier of the specific device may be a physical address, an IP address, a name, a number, and the like of the specific device. The mark may comprise one or any combination of numbers, letters, symbols. When the position of the identifier of the designated equipment of the scalar calculation macro instruction is null, determining that the scalar calculation macro instruction has no designated equipment; alternatively, when the field "identification of specified device" is not included in the scalar calculation macro, it is determined that the scalar calculation macro does not have a specified device.

In this implementation, the scalar compute macro may include therein an identification of one or more specified devices that execute the scalar compute macro. When the scalar calculation macro includes the identifier of the designated device and the resource of the designated device meets the execution condition, the first determining sub-module 111 may directly determine the designated device as the execution device, save the generation time for generating the execution instruction based on the scalar calculation macro, and ensure that the generated execution instruction can be executed by the corresponding execution device.

In one possible implementation, as shown in fig. 2, the instruction generating device 100 may further include a macro instruction generating module 13. The macro instruction generation module 13 is configured to receive a scalar calculation instruction to be executed, and generate a scalar calculation macro instruction according to the determined identifier of the specific device and the scalar calculation instruction to be executed.

In this implementation, the specifying device may be determined according to the operation type of the scalar calculation instruction to be executed, or the like. The received scalar calculation instruction to be executed can be one or more.

The scalar compute instruction to be executed may include at least one of: the method comprises the steps of a to-be-executed scalar addition calculation instruction, a to-be-executed scalar subtraction calculation instruction, a to-be-executed scalar multiplication calculation instruction and a to-be-executed scalar division calculation instruction.

The scalar compute instruction to be executed may include at least the following: an operation type, a first operand, a second operand, and an output address.

In this implementation, when there is one scalar calculation instruction to be executed, the determined identifier of the specific device may be added to the scalar calculation instruction to be executed, and a scalar calculation macro instruction is generated. For example, some scalar compute instruction m to be executed is "XXX … … param". Where XXX is the operation type and param is the instruction parameter. Its designated device m-1 may be determined from the operation type "XXX" of the scalar calculation instruction m to be executed. Then, an identifier (e.g., 09) specifying the device M-1 is added to the scalar calculation instruction M to be executed, and a scalar calculation macro instruction M "XXX 09, … … param" corresponding to the scalar calculation instruction M to be executed is generated. When the scalar calculation instruction to be executed is multiple, the determined identifier of the designated device corresponding to each scalar calculation instruction to be executed can be added to the scalar calculation instruction to be executed, and one scalar calculation macro instruction or multiple corresponding scalar calculation macro instructions can be generated according to the multiple scalar calculation instructions to be executed with the identifiers of the designated devices.

It should be understood that the instruction format and inclusion of scalar compute instructions to be executed may be arranged as desired by those skilled in the art, and the present disclosure is not limited thereto.

In one possible implementation, as shown in fig. 2, the instruction generating apparatus 100 may further include a resource obtaining module 14. The device determination module 11 may also include a second determination submodule 112. The resource obtaining module 14 is configured to obtain resource information of the alternative device. The second determining submodule 112 is configured to, when it is determined that the scalar calculation macro does not include the identifier of the specified device, determine, from the candidate device, an execution device for executing the scalar calculation macro according to the received scalar calculation macro and the resource information of the candidate device. Wherein the resource information may comprise a set of instructions contained by the alternative device. The instruction set included by the alternative device may be a set of instructions corresponding to the operation type of the one or more scalar compute macro instructions. The more instruction sets that the alternative device contains, the more types of scalar compute macro instructions the alternative device is capable of executing.

In this implementation, the second determination submodule 112 may determine, from the alternative devices, one or more running devices that are capable of executing the scalar calculation macro when it is determined that the scalar calculation macro does not include the identification of the specified device. Wherein the determined instruction set of the execution device includes an instruction set corresponding to a scalar compute macro. For example, the received scalar compute macro instruction is a scalar add compute macro instruction, and an alternate device containing an instruction set corresponding to the scalar add compute macro instruction may be determined to be a execute device to ensure that it can execute the generated execute instruction.

In one possible implementation, as shown in fig. 2, the device determining module 11 may further include a third determining sub-module 113. When it is determined that the scalar calculation macro includes the identifier of the specified device and the resource of the specified device does not satisfy the execution condition for executing the scalar calculation macro, the third determining submodule 113 determines the operating device according to the scalar calculation macro and the resource information of the alternative device.

In this implementation, when it is determined that the scalar calculation macro includes the identifier of the specified device and the resource of the specified device does not satisfy the execution condition, the third determination submodule 113 may determine that the specified device of the scalar calculation macro does not have the capability of executing the scalar calculation macro. The third determination submodule 113 may determine an execution device from among the alternative devices, and may determine an alternative device containing an instruction set corresponding to the scalar calculation macro instruction as the execution device.

In a possible implementation manner, the instruction generation module 12 is further configured to determine a data amount of the scalar calculation macro instruction according to the first operand and the second operand of the scalar calculation macro instruction, and generate the execution instruction according to the data amount of the scalar calculation macro instruction, and the resource information of the execution device. The resource information of the operating device may further include at least one of a storage capacity and a remaining storage capacity.

The storage capacity of the operating device may refer to the amount of binary information that the memory of the operating device can accommodate. The remaining storage capacity of the operating device may refer to the storage capacity that the operating device is currently available for instruction execution after the occupied storage capacity is removed. The resource information of the running device can characterize the running capability of the running device. The larger the storage capacity and the larger the remaining storage capacity are, the stronger the operation capability of the operation device is.

In this implementation, the instruction generating module 12 may determine a specific manner of splitting the scalar calculation macro according to the resource information of each running device, the data size of the scalar calculation macro, and the like, so as to split the scalar calculation macro and generate the running instruction corresponding to the running device.

In a possible implementation manner, the instruction generating module 12 may be configured to, when it is determined that there is one execution device and the data amount of the execution device is smaller than the data amount of the scalar calculation macro, split the scalar calculation macro into a plurality of execution instructions according to the data amount and the data amount of the execution device, so that the execution device sequentially executes the plurality of execution instructions. Wherein, the operation data amount of the operation device may be determined according to the resource information of the operation device. The operation data amount of the operation device may be determined according to the storage capacity or the remaining storage capacity of the operation device.

In this implementation, when it is determined that there is one execution device and the data amount of the execution device is greater than or equal to the data amount of the scalar calculation macro, the instruction generation module 12 may directly convert the scalar calculation macro into one execution instruction, and may split the scalar calculation macro into multiple execution instructions, which is not limited in this disclosure.

In a possible implementation manner, the instruction generating module 12 may be configured to, when it is determined that there are multiple running devices, split the scalar calculation macro instruction according to the running data amount of each running device and the data amount of the scalar calculation macro instruction, and generate a running instruction corresponding to each running device. Wherein the operation data amount of each operation device may be determined according to the resource information of each operation device.

In this implementation, the instruction generating module 12 may generate one or more operation instructions for each operating device according to the operation data amount of each operating device, so that the corresponding operating device can execute the operation instructions.

In a possible implementation manner, the instruction generating module 12 may further split the scalar calculation macro according to the scalar calculation macro and a preset scalar calculation macro splitting rule to generate the running instruction. The scalar computation macro instruction splitting rule may be determined according to a conventional scalar computation macro instruction splitting manner (e.g., splitting according to a processing procedure of a scalar computation macro instruction, etc.), in combination with a running data amount threshold of instructions that all alternative devices are capable of executing. And splitting the scalar calculation macro instruction into the operation instructions with the data quantity smaller than or equal to the operation data quantity threshold value so as to ensure that the generated operation instruction can be executed in the corresponding operation device (the operation device is any one of the alternative devices). The storage capacities (or remaining storage capacities) of all the candidate devices may be compared, and the determined minimum storage capacity (or remaining storage capacity) may be determined as an operation data amount threshold of the instruction that can be executed by all the candidate devices.

It should be understood that, the person skilled in the art can set the generation mode of the operation instruction according to the actual needs, and the present disclosure does not limit this.

In this embodiment, the operation instruction generated by the instruction generation module according to the scalar calculation macro instruction may be a to-be-executed scalar calculation instruction, or may be one or more analyzed instructions obtained by analyzing the to-be-executed scalar calculation instruction, which is not limited in this disclosure.

In one possible implementation, as shown in fig. 2, the instruction generating apparatus 100 may further include a queue building module 15. The queue building module 15 is configured to sort the operation instructions according to a queue sorting rule, and build an instruction queue corresponding to the operation device according to the sorted operation instructions.

In this implementation, an instruction queue uniquely corresponding to each execution device may be constructed for each execution device. The operating instructions can be sequentially sent to the operating equipment uniquely corresponding to the instruction queue according to the sequence of the operating instructions in the instruction queue; or the instruction queue may be sent to the execution device, so that the execution device sequentially executes the execution instructions in the instruction queue according to the order of the execution instructions in the instruction queue. By the mode, the operation equipment can execute the operation instruction according to the instruction queue, the operation instruction is prevented from being executed mistakenly and delayed, and the operation instruction is prevented from being omitted.

In this implementation, the queue sorting rule may be determined according to information such as an expected execution time for executing the execution instruction, a generation time of the execution instruction, and an operation type related to the execution instruction itself, which is not limited by this disclosure.

In one possible implementation, as shown in FIG. 2, instruction generation device 100 may also include an instruction dispatch module 16. The instruction dispatch module 16 is configured to send the execution instruction to the execution device, so that the execution device executes the execution instruction.

In this implementation, when there is one execution instruction executed by the execution device, the execution instruction may be directly sent to the execution device. When the number of the operation instructions executed by the operation device is multiple, all of the multiple operation instructions may be sent to the operation device, so that the operation device sequentially executes the multiple operation instructions. The plurality of operation instructions can also be sequentially sent to the corresponding operation equipment, wherein after the operation equipment completes the current operation instruction, the next operation instruction corresponding to the current operation instruction is sent to the operation equipment each time. The manner in which the person skilled in the art can send the operation instruction to the operation device is set, and the present disclosure does not limit this.

In one possible implementation, as shown in FIG. 2, the instruction dispatch module 16 may include an instruction assembly submodule 161, an assembly translation submodule 162, and an instruction issue submodule 163. The instruction assembling sub-module 161 is used for generating an assembling file according to the operation instruction. The assembly translation sub-module 162 is used to translate the assembly file into a binary file. The instruction sending submodule 163 is configured to send the binary file to the operating device, so that the operating device executes the operating instruction according to the binary file.

By the mode, the data volume of the operation instruction can be reduced, the time for sending the operation instruction to the operation equipment is saved, and the conversion and execution speed of the scalar calculation macro instruction is increased.

In this implementation manner, after the binary file is sent to the running device, the running device may decode the received binary file to obtain a corresponding running instruction, and execute the obtained running instruction to obtain an execution result.

In a possible implementation manner, the running device 200 may be one or any combination of a CPU, a GPU, and an embedded Neural-Network Processing Unit (NPU). In this way, the speed at which the apparatus generates the execution instruction from the scalar calculation macro is increased.

In one possible implementation, the instruction generating apparatus 100 may be provided in the CPU and/or the NPU. To implement the process of generating the execution instruction from the scalar computing macro by the CPU and/or NPU, provides more possible ways for the instruction generating apparatus 100 to be implemented.

In a possible implementation, the execution device 200 further comprises a storage module 23. The memory module 23 may include at least one of a register and a cache, and the cache may include a scratch pad cache. The cache may be used to store data. The registers may be used to store scalar data within the data.

In one possible implementation, the control module 21 may include an instruction storage submodule 211 and an instruction processing submodule 212. The instruction storage submodule 211 is used for storing the operation instruction. The instruction processing submodule 212 is configured to parse the operation instruction to obtain a plurality of parsing instructions.

In one possible implementation, the control module 21 may further include a store queue submodule 213. The storage queue submodule 213 is configured to store an operation instruction queue, where the operation instruction queue includes an operation instruction that needs to be executed by the operation device and a plurality of parsing instructions. And all the instructions in the operation instruction queue are sequentially arranged according to the execution sequence.

In a possible implementation, the execution module 22 may further include a dependency processing sub-module 221. The dependency relationship processing submodule 221 is configured to cache the first parsing instruction in the instruction storage submodule when it is determined that the first parsing instruction has an association relationship with a zeroth parsing instruction before the first parsing instruction, and extract the first parsing instruction from the instruction storage submodule after the zeroth parsing instruction is executed and send the first parsing instruction to the execution module.

The association relationship between the first parsing instruction and the zeroth parsing instruction before the first parsing instruction may include: the first storage address interval for storing the data required by the first analysis instruction and the zeroth storage address interval for storing the data required by the zeroth analysis instruction have an overlapping area. Conversely, the no association relationship between the first parse instruction and the zeroth parse instruction may be that the first memory address interval and the zeroth memory address interval have no overlapping area.

In one possible implementation, a scalar compute macro instruction may refer to a macro instruction used to perform arithmetic operations on scalars. For example, a macro instruction that performs calculation such as scalar addition, scalar subtraction, scalar multiplication, and scalar division on scalars. Different types of scalar compute macro instructions correspond to different operation types. For example, the operation type corresponding to the scalar subtraction macro is SSUB, and the operation type corresponding to the scalar addition macro is SADD.

In this embodiment, for a scalar compute macro-instruction, it must include an opcode, i.e., an operation type, and at least one operation domain that includes an identification of a specified device, a first operand, a second operand, and an output address. An opcode may be the portion of an instruction or field (usually denoted by a code) specified in a computer program that is to perform an operation, and is an instruction sequence number that tells the device executing the instruction which instruction specifically needs to be executed. The operation domain may be a source of all data required for executing the corresponding instruction, including parameter data, data to be operated on or processed, a corresponding operation method, or an address or the like storing the parameter data, the data to be operated on or processed, the corresponding operation method.

It should be noted that, although the scalar computing instruction processing system is described above by taking the above embodiment as an example, those skilled in the art will understand that the present disclosure should not be limited thereto. In fact, the user can flexibly set each module according to personal preference and/or actual application scene, as long as the technical scheme of the disclosure is met.

The working process and principle of the scalar calculation instruction processing system for generating and executing the operation instruction according to a certain scalar calculation macro instruction are as follows.

Resource acquisition module 14

And acquiring resource information of the alternative device, wherein the resource information comprises the residual storage capacity and the storage capacity of the alternative device and an instruction set contained in the alternative device. The resource obtaining module 14 sends the obtained resource information of the candidate device to the device determining module 11 and the instruction generating module 12.

The device determination module 11 (including a first determination sub-module 111, a second determination sub-module 112, and a third determination sub-module 113)

Upon receiving the scalar calculation macro, an execution device that executes the scalar calculation macro is determined based on the received scalar calculation macro. For example, the following scalar compute macro is received. Where scalar compute macro instructions may be from different platforms.

Scalar calculation macro instruction 1: @ XXX #01 … …

Scalar calculation macro instruction 2: @ SSS #02 … …

Scalar calculation macro instruction 3: @ DDD #04 … …

Scalar calculation macro instruction 4: @ NNN … …

When the first determination submodule 111 determines that the scalar calculation macro includes the identifier of the designated device and determines that the designated device includes the instruction set corresponding to the scalar calculation macro, the first determination submodule 111 may determine the designated device as an execution device that executes the scalar calculation macro, and transmit the identifier of the determined execution device to the instruction generation module 12. For example, the first determination submodule 111 may determine a specified device corresponding to the identification 01, such as CPU-2 (the CPU-2 includes an instruction set corresponding to the scalar calculation macro 1), as an execution device for executing the scalar calculation macro 1. A designated device such as CPU-1(CPU-1 contains an instruction set corresponding to scalar calculation macro instruction 2) to which the identifier 02 corresponds may be determined as an execution device for executing the scalar calculation macro instruction 2.

When the third determination submodule 113 determines that the scalar calculation macro includes the identifier of the specified device and determines that the instruction set corresponding to the scalar calculation macro is not included in the specified device, the third determination submodule 113 may determine, as the execution device, the candidate device including the instruction set corresponding to the scalar calculation macro, and transmit the identifier of the determined execution device to the instruction generation module 12. For example, when it is determined that the instruction set corresponding to the scalar calculation macro instruction 3 is not included in the specified device corresponding to the identifier 04, the third determination submodule 113 may determine, as the execution device for executing the scalar calculation macro instruction 3, an alternative device such as NPU-n, NPU-2 that includes the instruction set corresponding to the operation type DDD of the scalar calculation macro instruction 3.

When the second determining submodule 112 determines that the scalar calculation macro instruction does not have the identifier of the specified device (the position corresponding to the identifier of the specified device is empty, or the scalar calculation macro instruction does not include the field of "identifier of the specified device"), the second determining submodule 112 may determine the operating device from the alternative devices according to the scalar calculation macro instruction and the resource information of the alternative devices (the specific determination process is detailed in the related description of the second determining submodule 112 above), and send the determined identifier of the operating device to the instruction generating module 12. For example, since the scalar calculation macro 4 does not have the identifier of the specified device, the second determination submodule 112 may determine, from the candidate device, an execution device, for example, GPU-n (the GPU-n includes an instruction set corresponding to the operation type NNN) for executing the scalar calculation macro 4, according to the operation type NNN of the scalar calculation macro 4 and the resource information (the included instruction set) of the candidate device.

Instruction generation module 12

When there is one execution device, the scalar calculation macro may be split into multiple execution instructions, and the multiple execution instructions may be sent to the queue building module 15. For example, a plurality of execution instructions 2-1, 2-2, …, 2-n are generated from the data amount of the scalar calculation macro instruction 2 and the execution data amount of the execution device CPU-1. And generating a plurality of operating instructions 4-1, 4-2, … and 4-n according to the data volume of the scalar calculation macro instruction 4 and the operating data volume of the operating device GPU-n.

When it is determined that there is one execution device, an execution instruction may be generated from the scalar calculation macro and sent to the queue building block 15. For example, one execution instruction 1-1 is generated from the data amount of the scalar calculation macro instruction 1 and the execution data amount of the execution device CPU-2.

When a plurality of operating devices are determined, the scalar calculation macro is split, an operating instruction corresponding to each operating device is generated, and the operating instruction is sent to the queue building module 15. For example, the data amount of the macro instruction 3, the operation data amount of the operation device NPU-n, and the operation data amount of the operation device NPU-2 are calculated from scalars, a plurality of operation instructions 3-1, 3-2, …, 3-n are generated for the operation device NPU-n, and a plurality of operation instructions 3 ' -1, 3 ' -2, …, 3 ' -n are generated for the operation device NPU-2.

Queue building Block 15

When receiving the operation instruction, all the operation instructions to be executed by each operation device are sorted according to the queue sorting rule, a unique corresponding instruction queue is constructed for each operation device according to the sorted operation instructions, and the instruction queue is sent to the instruction dispatching module 16. In particular, the amount of the solvent to be used,

for an operation instruction 1-1 executed by the operation device CPU-2. The instruction queue CPU-2 "constructed corresponding to the execution device CPU-2 includes only the execution instructions 1-1.

And sequencing the plurality of operating instructions 2-1, 2-2, … and 2-n according to a queue sequencing rule, and constructing an instruction queue CPU-1' corresponding to the operating equipment CPU-1 according to the sequenced plurality of operating instructions 2-1, 2-2, … and 2-n.

For the plurality of execution instructions 3 ' -1, 3 ' -2, …, 3 ' -n executed by the execution device NPU-2. The plurality of operating instructions 3 '-1, 3' -2, …, 3 '-n are ordered according to a queue ordering rule, and an instruction queue NPU-2 "corresponding to the operating device NPU-2 is constructed according to the ordered plurality of operating instructions 3' -n, …, 3 '-2, 3' -1.

For the plurality of execution instructions 4-1, 4-2, …, 4-n executed by the execution device GPU-n. And sequencing the plurality of operating instructions 4-1, 4-2, … and 4-n according to a queue sequencing rule, and constructing an instruction queue GPU-n' corresponding to the operating equipment GPU-n according to the sequenced plurality of operating instructions 4-1, 4-2, … and 4-n.

Instruction dispatch module 16

After the instruction queues are received, the operation instructions in each instruction queue are sequentially sent to corresponding operation equipment, so that the operation equipment executes the operation instructions. For example, the execution instruction 1-1 included in the instruction queue CPU-2 ″ is sent to its corresponding execution device CPU-2. And sequentially sending a plurality of running instructions 2-1, 2-2, … and 2-n in the instruction queue CPU-1' to the corresponding running equipment CPU-1. And sequentially sending the plurality of operating instructions 3-n, …, 3-2 and 3-1 in the instruction queue NPU-n' to the corresponding operating equipment NPU-n. And sequentially sending the plurality of running instructions 3 '-n, …, 3' -2 and 3 '-1 in the instruction queue NPU-2' to the corresponding running equipment NPU-2. And sequentially sending the multiple operating instructions 4-1, 4-2, … and 4-n in the queue GPU-n' to the corresponding operating equipment GPU-n.

After receiving the instruction queue, the operation device CPU-2, the operation device CPU-1, the operation device NPU-n and the operation device NPU-2 execute the operation instructions in sequence according to the arrangement sequence of the operation instructions in the instruction queue. Taking the operating device CPU-2 as an example, a specific process of executing the received operating instruction will be described. The running device CPU-2 comprises a control module, an execution module and a storage module. The control module comprises an instruction storage submodule, an instruction processing submodule and a storage queue submodule, and the execution module comprises a dependency relationship processing submodule, which refers to the relevant description about the operation equipment in detail.

Assume that the execution instruction 1-1 generated from the scalar calculation macro instruction 1 is "@ XXX … …". After receiving the operation instruction 1-1, the operation device CPU-2 executes the operation instruction 1-1 as follows:

the control module of the operating device CPU-2 obtains data, a neural network model and an operating instruction 1-1. The instruction storage submodule is used for storing an operation instruction 1-1. The instruction processing submodule is used for analyzing the operation instruction 1-1, obtaining a plurality of analysis instructions such as an analysis instruction 0, an analysis instruction 1 and an analysis instruction 2, and sending the plurality of analysis instructions to the storage queue submodule and the execution module. The storage queue submodule is used for storing an operation instruction queue, the operation instruction queue comprises an analysis instruction 0, an analysis instruction 1, an analysis instruction 2 and other operation instructions which are required to be executed by the CPU-2 of the operation equipment, and all the instructions are sequentially arranged in the operation instruction queue according to the execution sequence. For example, the obtained sequence of the execution of the multiple analysis instructions is analysis instruction 0, analysis instruction 1, and analysis instruction 2, and there is an association relationship between analysis instruction 1 and analysis instruction 0.

After the execution module of the operating device CPU-2 receives the plurality of analysis instructions, the dependency relationship processing submodule judges whether an association relationship exists among the plurality of analysis instructions. And the dependency relationship processing submodule determines that the analysis instruction 1 and the analysis instruction 0 have an incidence relationship, caches the analysis instruction 1 into the instruction storage submodule, and extracts the analysis instruction 1 from the cache and sends the analysis instruction 1 to the execution module after determining that the analysis instruction 0 is executed, so that the execution module can execute the analysis instruction.

The execution module receives and executes the resolving instruction 0, the resolving instruction 1 and the resolving instruction 2 to complete the operation of the operation instruction 1-1.
