Embodiment Construction

[0064] The disclosure provides a matrix calculation device, including a storage unit, a register unit and a matrix operation unit, the storage unit stores a matrix, and the register unit stores an address of the matrix storage. The matrix operation unit obtains the matrix address in the register unit according to the matrix operation instruction. , and then obtain a corresponding matrix in the storage unit according to the matrix address, and then perform a matrix operation according to the obtained matrix to obtain a matrix operation result. In this disclosure, the matrix data involved in the calculation is temporarily stored in the high-speed temporary memory, so that the matrix operation process can support data of different widths more flexibly and effectively, and improve the execution performance of tasks involving a large number of matrix calculations.

Abstract

The invention provides a matrix calculation instruction and a method therefor. The matrix calculation instruction comprises an operation code and an operation domain; the operation code is used for identifying different matrix calculation instructions; and the operation domain is used for indicating data information of the matrix calculation instruction, wherein the data information is a registernumber corresponding to an immediate operand of a specific value or data of a specific size. The matrix data participating in calculation is temporarily stored in a scratch pad memory, so that the data different in width can be supported more flexibly and effectively in a matrix calculation process, and the executive performance of a task containing a large amount of matrix calculations is improved.

Description

technical field [0001] The disclosure relates to a matrix operation instruction and a method thereof, which are used for performing matrix operations according to the matrix operation instruction, and can well solve the problem that more and more algorithms in the current computer field include a large number of matrix operations. Background technique [0002] At present, more and more algorithms in the computer field involve matrix operations. Taking artificial neural network algorithms as an example, various neural network algorithms contain a large number of matrix operations. In the neural network, the operation expression of the output neuron is y=f(wx+b), where w is a matrix, x and b are matrices, and the process of calculating the output matrix y is to multiply the matrix w by the matrix x, and add Matrix b, and then perform an activation function operation on the obtained matrix (that is, perform an activation function operation on each element in the matrix). There...
