Problems solved by technology

[0003] At present, when performing matrix operations, especially matrix multiplication operations, due to the characteristics of matrix multiplication, it is often necessary to multiply the corresponding elements of the matrix by reading the matrix data multiple times, and after the matrix data is read into the register, the register The data transmitted on all channels of the thread is the same, and there is a lot of redundancy in the data between threads, which will also cause additional power consumption
Existing data processing methods can realize the copying of data between threads by executing specific instructions, but the instructions used are not suitable for matrix operation operations, and the instructions for operating data between threads exist as separate instructions independent of operation instructions. Still less efficient for actual data processing

Abstract

The invention provides a data processing method and device for matrix multiplication, equipment and a storage medium. The data processing method comprises the steps of obtaining a matrix multiplication instruction and a data selection instruction; determining a first vector general register storing a first operation matrix and a second vector general register storing a second operation matrix based on the matrix multiplication instruction and the data selection instruction; determining target operation data in a second number of operation data of the second operation matrix based on the data selection instruction; respectively providing a first number of operation data of the first operation matrix to the first number of multipliers as a first multiplication factor, and providing the target operation data to the first number of multipliers as a second multiplication factor.

Description

technical field [0001] The present disclosure relates to the field of data processing, and more particularly, to a data processing method and device for matrix multiplication. Background technique [0002] A graphics processing unit (GPU) includes a large number of data processing units, and each data processing unit is a single instruction multiple data (SIMD) structure. By executing an instruction, multiple threads are simultaneously controlled to perform the same operation. In each SIMD structure, It has a dedicated set of vector general-purpose registers (VGPR) and a large number of parallel-executable arithmetic units, such as multiplication units. Because the SIMD structure has a high degree of parallelism, the SIMD structure is widely used in matrix operations. [0003] At present, when performing matrix operations, especially matrix multiplication operations, due to the characteristics of matrix multiplication, it is often necessary to multiply the corresponding ele...
