Title:
SPARSE MATRIX COMPUTATION METHOD AND ACCELERATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/022117
Kind Code:
A1
Abstract:
A sparse matrix computation method, comprising: when at least one of two multiplied matrices is a sparse matrix, determining whether the uniformity of the sparse matrices satisfies a preset condition, wherein the uniformity is used to indicate the distribution uniformity of non-zero elements in the sparse matrix; if so, performing multiplication processing on the two matrices using a first mode, wherein the first mode involves shifting and compressing the sparse matrix to obtain at least one set of non-zero elements, and respectively multiplying each set of non-zero elements in at least one set of non-zero elements by the other matrix and performing shifting to obtain a result matrix; otherwise, performing multiplication processing on the two matrices using a second mode, wherein the second mode involves respectively multiplying each non-zero element in the sparse matrix by the other matrix to obtain a result matrix.
