Video data processing method and system, and relevant assemblies

Abstract

A video data processing method, including: obtaining three-dimensional feature data and three-dimensional weight data corresponding to video data; separately preprocessing the three-dimensional feature data and the three-dimensional weight data to obtain a feature value matrix and a weight value matrix; and inputting the feature value matrix and the weight value matrix into a plurality of three-dimensional systolic arrays for parallel computing to obtain a video data processing result. The present method can fully expand the degree of parallelism of computation and a four-dimensional systolic computation architecture is constructed by using multiple three-dimensional systolic arrays, so as to perform parallel computing on a three-dimensional feature value matrix and a three-dimensional weight value matrix, thereby shortening the computation time of three-dimensional convolution, and improving the video data processing efficiency.
