The operation type may refer to a type of the operation performed by the matrix vector calculation macro-instruction on the data, and represents a specific type of the matrix vector calculation macro-instruction, for example, when an operation type of a certain matrix vector calculation macro-instruction is "XXX", the specific type of the operation performed by the matrix vector calculation macro-instruction on the data may be determined according to "XXX". The instruction set required for executing the matrix vector calculation macro instruction may be determined according to the operation type, for example, when the operation type of a certain matrix vector calculation macro instruction is "XXX", the instruction set required for the certain matrix vector calculation macro instruction is all instruction sets required for performing the processing corresponding to "XXX".

The operands may include the length of the register, the address of the register, the identity of the register, the immediate, and the like. The immediate is the number given in the immediate addressing mode instruction.

Instruction generation module 12 may generate one or more execution instructions. When a plurality of generated operating instructions are provided, the plurality of operating instructions may be executed in the same operating device or different operating devices, and the present disclosure is not limited thereto.

The matrix vector calculation instruction generation device provided by the embodiment of the disclosure comprises an equipment determination module and an instruction generation module, wherein the equipment determination module is used for calculating a macro instruction according to a received matrix vector and determining an operation device for executing the matrix vector calculation macro instruction.

The macro instruction generating module 13 is configured to receive a to-be-executed matrix vector calculation instruction, and generate a matrix vector calculation macro instruction according to the determined identifier of the specific device and the to-be-executed matrix vector calculation instruction.

In this implementation, the specified device may be determined according to the operation type, the input amount, the output amount, and the like of the matrix vector calculation instruction to be executed. The received matrix vector calculation instruction to be executed can be one or more.

The matrix vector calculation instruction to be executed may include at least one of: the method comprises a to-be-executed matrix multiplication vector calculation instruction, a to-be-executed vector multiplication matrix calculation instruction, a to-be-executed tensor calculation instruction, a to-be-executed matrix addition calculation instruction and a to-be-executed matrix subtraction calculation instruction.

In this implementation, when there is one matrix vector calculation instruction to be executed, the determined identifier of the specific device may be added to the matrix vector calculation instruction to be executed, and a matrix vector calculation macro instruction is generated. For example, some matrix vector calculation 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 matrix vector calculation instruction m to be executed. Then, an identification (e.g., 09) specifying the device M-1 is added to the matrix vector calculation instruction M to be executed, and a matrix vector calculation macro instruction M "XXX 09, … … param" corresponding to the matrix vector calculation instruction M to be executed is generated. When the matrix vector calculation instruction to be executed is multiple, the identifier of the specified device corresponding to each determined matrix vector calculation instruction to be executed may be added to the matrix vector calculation instruction to be executed, and one matrix vector calculation macro instruction or multiple corresponding matrix vector calculation macro instructions may be generated according to the multiple matrix vector calculation instructions to be executed with the identifier of the specified device.

It should be understood that the instruction format and the content of the matrix vector calculation instruction to be executed may be set by those skilled in the art according to the needs, and the present disclosure does not limit this.

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 an operating device when it is determined that the matrix vector calculation macro includes an identifier of the specified device and a resource of the specified device meets an execution condition for executing the matrix vector calculation macro. Wherein, the execution condition may include: the specifying device contains an instruction set corresponding to a matrix vector computation macro instruction.

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

In one possible implementation, as shown in fig. 2, the apparatus may further include a resource acquisition 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 matrix vector calculation macro does not include the identifier of the specified device, determine, from the candidate devices, an operating device for executing the matrix vector calculation macro according to the received matrix vector calculation macro and resource information of the candidate devices. Wherein the resource information may comprise a set of instructions contained by the alternative device. The instruction set included in the alternative device may be a set of instructions corresponding to one or more types of operation of the matrix vector computation macro-instructions. The more instruction sets the candidate device contains, the more types of matrix vector computation macro instructions the candidate device is capable of executing.

In this implementation, when determining that the matrix vector calculation macro does not include the identifier of the specific device, the second determining submodule 112 may determine, from the candidate devices, one or more operating devices capable of executing the matrix vector calculation macro. Wherein the determined instruction set of the running device comprises an instruction set corresponding to a matrix vector computation macro. For example, where the received matrix vector computation macro is a matrix multiplication vector computation macro, an alternate device containing an instruction set corresponding to the matrix multiplication vector computation macro may be determined to be the executing device to ensure that it can execute the generated executing 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 matrix vector calculation macro instruction contains the identifier of the specified device and the resource of the specified device does not meet the execution condition for executing the matrix vector calculation macro instruction, the third determining submodule 113 determines the operating device according to the matrix vector calculation macro instruction and the resource information of the alternative device.

In this implementation, when it is determined that the matrix vector calculation macro includes the identifier of the specified device and the resource of the specified device does not satisfy the execution condition, the third determining sub-module 113 may determine that the specified device of the matrix vector calculation macro does not have the capability of executing the matrix vector calculation macro. The third determination submodule 113 may determine an execution device from among candidate devices, and may determine, as the execution device, a candidate device containing an instruction set corresponding to the operation type of the matrix vector calculation macro instruction.

In a possible implementation manner, as shown in fig. 2, the matrix vector calculation macro may include at least one of an input quantity and an output quantity, and the instruction generating module 12 is further configured to determine a data quantity of the matrix vector calculation macro, and generate the operation instruction according to the data quantity of the matrix vector calculation macro, and resource information of the operation device. The data amount of the matrix vector calculation macro instruction may be determined according to at least one of the input amount and the output amount, and 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 matrix vector calculation macro instruction according to the resource information of each operating device, the data amount of the matrix vector calculation macro instruction, and the like, so as to split the matrix vector calculation macro instruction and generate an operating instruction corresponding to the operating device.

In one possible implementation, as shown in fig. 2, the instruction generating module 12 may include a first instruction generating submodule 121. The first instruction generation submodule 121 is configured to split the matrix vector calculation macro instruction into a plurality of operation instructions according to the operation data amount and the data amount of the operation device when it is determined that the number of the operation devices is one and the operation data amount of the operation device is smaller than the data amount of the matrix vector calculation macro instruction, so that the operation device sequentially executes the plurality of operation instructions. The operation data amount of the operation device may be determined according to the resource information of the operation device, each operation instruction may include at least one of an operation input amount and an operation output amount, and the operation input amount and the operation output amount may be determined according to the operation data amount.

In this implementation, 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. The operation input quantity and the operation output quantity are required to be less than or equal to the operation data quantity so as to ensure that the generated operation instruction can be executed by the operation equipment. The operation input amount (or operation output amount) of different operation instructions in the plurality of operation instructions may be the same or different, and the disclosure does not limit this.

In this implementation, when it is determined that there is one operation device and the operation data amount of the operation device is greater than or equal to the data amount of the matrix vector calculation macro, the first instruction generation sub-module 121 may directly convert the matrix vector calculation macro into one operation instruction, and may also split the matrix vector calculation macro into a plurality of operation instructions, which is not limited in this disclosure.

In one possible implementation, as shown in FIG. 2, the instruction generation module 12 may include a second instruction generation submodule 122. The second instruction generating submodule 122 is configured to split the matrix vector calculation macro instruction according to the operation data amount and the data amount of each operating device when it is determined that a plurality of operating devices are provided, and generate an operation instruction corresponding to each operating device. The operation data amount of each operating device may be determined according to the resource information of each operating device, the operation instruction may include at least one of an operation input amount and an operation output amount, and the operation input amount and the operation output amount are determined according to the operation data amount of the operating device that executes the operation instruction.

In this implementation, the operation input quantity and the operation output quantity need to be less than or equal to the operation data quantity to ensure that the generated operation instruction can operate the device to execute. The second instruction generation sub-module 122 may generate one or more operation instructions for each operation device according to the operation data amount of each operation device, so as to be executed by the corresponding operation device.

In the above implementation, the operation instruction includes at least one of the operation input quantity and the operation output quantity, except that the data quantity of the operation instruction can be limited to be executed by the corresponding operation device. And special limiting requirements of different operation instructions on operation input quantity and/or operation output quantity can be met.

In a possible implementation manner, for some operation instructions that do not have a special limited requirement on the operation input amount and/or the operation output amount, where the operation input amount and/or the operation output amount may not be included, a default operation input amount and a default operation output amount may be preset, so that when it is determined that the operation input amount and the operation output amount do not exist in the received operation instructions, the operation device may use the default operation input amount and the default operation output amount as the operation input amount and the operation output amount of the operation instructions. By presetting the default operation input quantity and the default operation output quantity, the generation process of the operation instruction can be simplified, and the generation time of the operation instruction is saved.

In one possible implementation, the default input quantity and the default output quantity of the macro instruction may be preset for different types of matrix vectors. When the input quantity and the output quantity are not included in the matrix vector calculation macro instruction, the corresponding preset default input quantity and default output quantity can be used as the input quantity and the output quantity of the matrix vector calculation macro instruction. And then determining the data volume of the matrix vector calculation macro instruction according to the default input quantity and/or the default output quantity, calculating the resource information of the macro instruction and the operating equipment according to the data volume of the matrix vector calculation macro instruction and the matrix vector, and generating the operating instruction. When the matrix vector calculation macro instruction does not include the input quantity and the output quantity, the generated operation instruction may not include the operation input quantity and the operation output quantity, and may include at least one of the operation input quantity and the operation output quantity. When the operation instruction does not include the operation input amount and/or the operation output amount, the operation device may execute the operation instruction according to a preset default operation input amount and/or a default operation output amount.

In a possible implementation manner, the instruction generating module 12 may further split the matrix vector calculation macro instruction according to the matrix vector calculation macro instruction and a preset matrix vector calculation macro instruction splitting rule, so as to generate the operation instruction. The matrix vector calculation macro instruction splitting rule may be determined according to a conventional matrix vector calculation macro instruction splitting manner (for example, splitting according to a processing procedure of a matrix vector calculation macro instruction, and the like), and in combination with an operation data amount threshold of an instruction that can be executed by all the candidate devices. And splitting the matrix vector calculation macro instruction into operation instructions of which the operation input quantity and the operation output quantity are less than or equal to an operation data quantity threshold value so as to ensure that the generated operation instructions can be executed in corresponding operation equipment (the operation equipment is any one of the alternative equipment). 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 generating module according to the matrix vector calculation macro instruction may be a to-be-executed matrix vector calculation instruction, or may be one or more analyzed instructions obtained by analyzing the to-be-executed matrix vector calculation instruction, which is not limited in this disclosure.

In one possible implementation, as shown in fig. 2, the apparatus 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 a predicted execution time for executing the operation instruction, a generation time of the operation instruction, an operation input amount, an operation output amount, and an operation type related to the operation instruction itself, which is not limited by this disclosure.

In one possible implementation, as shown in FIG. 2, the apparatus 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 matrix vector 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 may be one or any combination of a CPU, a GPU, and an embedded Neural-Network Processing Unit (NPU). In this way, the speed of the device for generating the operation instruction according to the matrix vector calculation macro instruction is improved.

In one possible implementation, the apparatus may be provided in the CPU and/or the NPU. The process of generating the operation instruction according to the matrix vector calculation macro instruction is realized by the CPU and/or the NPU, and more possible modes are provided for the realization of the device.

In one possible implementation, the matrix-vector computation macro-instruction may refer to a macro-instruction used to compute matrices and vectors. For example, the macro instruction performs calculation such as matrix multiplication vector calculation, vector multiplication matrix calculation, tensor calculation, matrix addition calculation, and matrix subtraction calculation on the matrix and the vector. The different types of matrix vector calculation macro-instructions correspond to different operation types, for example, the operation type corresponding to the matrix addition calculation macro-instruction is MADD, and the operation type corresponding to the matrix multiplication vector calculation macro-instruction is MMV.

The operating device comprises a control module and an execution module.
