Vector multiply-accumulate processing method, apparatus, storage medium, and program product

Abstract

A vector multiply-accumulate processing method and device, a storage medium and a program product, the method comprising: in response to receiving a first multiply-accumulate instruction, the first multiply-accumulate instruction comprising a first register, a second register, a target register and a first coefficient z, selecting (z) elements from an update coefficient vector as current update coefficients according to the first coefficient z, and copying each current update coefficient to (z) respectively, wherein (z) and (z) are both preset functions of the first coefficient z, and the values of (z) and (z) are both greater than or equal to 1, the first register is used to store the update coefficient vector, the second register is used to store a first data matrix, the target register is used to store a second data matrix, and the first data matrix and the second data matrix have the same number of columns; multiplying (z)*(z) current update coefficients with elements in (z) rows and (z) columns in the second register respectively, and adding the multiplication results with elements in corresponding positions of the target register to obtain a vector multiply-accumulate result.
