Device and method for executing vector outer product operation

Abstract

The invention provides a device and method for executing vector outer product operation. The device comprises a storage unit, a register unit and a vector outer product operation unit, wherein the storage unit is internally stored with vectors; the register unit is internally stored with addresses for vector storage; and the vector outer product operation unit is used for obtaining a vector address in the register unit according to an assorted instruction, obtaining a corresponding vector in the storage unit according to the vector address and carrying out vector outer product operation according to the obtained vector so as to obtain an operation result. According to the device and method, vector data participating in the calculation is temporarily stored on a scratch pad memory, so that the data with different widths can be supported more flexibly and effectively in the vector outer product operation process and then the execution performance of applications comprising vector outer products is enhanced.

Description

technical field [0001] The invention relates to a vector outer product operation device and method, which are used for performing vector outer product operation according to a vector outer product operation instruction. Background technique [0002] In the category of vector spaces, homomorphisms between objects are all linear maps. But in fact, we often encounter the concept of "bilinear mapping". For example, the inner product is a bilinear mapping V×V→C. We hope to attribute the property of "bilinear" to the category of vector space. One way is to construct a vector space Z related to V and W, so that all "bilinear maps" defined on V×W can be replaced by a "only" "linear map" defined on Z. This Z is called the tensor product (outer product) of V and W. For example, the magnitude of the calculated value of the vector outer product a×b is |a|·|b|·sin<a, b>. [0003] Among the existing applications in the computer field, applications related to vector operations are...
