Abstract

The embodiment of the invention discloses a matrix-to-multiplier, relates to the technical field of data calculation, and aims to perform block calculation on two matrixes. The matrix multiplier comprises: 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;and the controller is used for controlling the first matrix and the second matrix to perform partitioning according to a preset program or instruction, and controlling the operational circuit to perform multiplication operation on corresponding partitions in the first memory and the second memory according to a partitioning result of the controller. The matrix multiplier may be used to multiply two matrices.

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 Regl, which can realize the multiplication between the corresponding elements of Reg0 and Reg1, and finally complete the accumulation operation through the addition tree, and calculate the data C of the i-th row and j-th column of the matri...
