Abstract

The embodiment of the invention discloses a matrix multiplier, relates to the technical field of data calculation, and aims to perform block calculation on two matrixes. The matrix multiplier includes: a first memory, a second memory, an operational circuit and a controller, wherein the operational circuit can be in data communication with the first memory and the second memory through a bus; andthe controller is used for controlling the first matrix and the second matrix to separate; according to a preset program or an instruction, and controlling the operation circuit to multiply the corresponding blocks in the first memory and the second memory according to the dividing result of the controller. The matrix multiplier can be used for carrying out multiplication operation on two matrixes.

Description

technical field [0001] The invention relates to the technical field of computing, in particular to a matrix multiplier. Background technique [0002] Currently, to calculate the product of two matrices A and B, it can be calculated in either of the following two ways: [0003] Method 1: Computation is performed by a vector processor. [0004] Assuming C=A*B, the number of elements that can be calculated by the vector processor at the same time is M, see figure 1 , the vector processor will take the i-th row vector of matrix A (including element A i1 、A i2 ,...,A i(M-1) 、A iM ) into the source register Reg0, and then the jth column vector of matrix B (including element B j1 , B j2 ,...,B j(M-1) , B jM ) is loaded into the register Reg1, the multiplication between the corresponding elements of Reg0 and Reg1 can be realized, and finally the accumulation operation is completed through the addition tree, and the data C of the i-th row and j-th column of the matrix C is c...
