Problems solved by technology

[0003] Therefore, the existing vector operation instructions cannot realize variable-scale vector or matrix operations, and the current vector operation instructions can only implement one type of operation. Instructions cannot implement more than two types of operations, so the existing vector operations have high computational overhead and high energy consumption

Abstract

The invention provides an operation device. The operation device is used for executing operation according to an extended instruction and comprises a storage, an operation unit and a control unit; theextended instruction comprises an operation code and an operation domain, and the storage is used for storing a vector; the control unit is used for obtaining the extended instruction, analyzing theextended instruction to obtain a vector operation instruction and a second operation instruction, determining the calculation sequence of the vector operation instruction and the second operation instruction according to the vector operation instruction and the second operation instruction and reading an input vector corresponding to an input vector address from the storage; the operation unit isused for executing the vector operation instruction and the second operation instruction on the input vector according to the calculation sequence to obtain a result of the extended instruction. The operation device has the advantages of being low in power consumption and small in calculation expenditure.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a computing device and related products. Background technique [0002] In modern general-purpose and special-purpose processors, more and more calculation instructions (such as vector instructions) are introduced to perform operations. Vector instructions are instructions that enable the processor to perform vector or matrix operations, such as addition and subtraction of vectors, inner product of vectors, matrix multiplication, and matrix convolution. In the vector instruction, at least one input is a vector or a matrix, or the operation result is a vector or a matrix. Vector instructions can perform parallel calculations by calling the vector processing components inside the processor to improve the operation speed. In the existing vector instructions, the vector or matrix in its operand or result is generally fixed in size. For example, the vector instruction in the ve...
