Data processing method and device for performing a convolution operation

Abstract

A data processing method comprises: if detecting that a number of image data to be transferred is greater than zero wherein the number of image data is a product of a number of input image data and a number of output image data, and a first available storage space of a FIFO memory is greater than or equal to a storage space occupied by an N number of input image data, transferring the N input image data in a first memory to the first FIFO memory; if detecting that a number of weight data to be transferred is greater than zero wherein the number of weight data is a product of the number of input image data and the number of output image data, and a second available storage space of a second FIFO memory is greater than or equal to a storage space occupied by an M number of weight data, transferring the M weight data in a second memory to the second FIFO memory; when the number of input image data cached in the first FIFO memory and the number of weight data cached in the second FIFO memory are greater than or equal to 1, performing a convolution operation on input image data i read from the first FIFO memory and weight data w read from the second FIFO memory to obtain output image data corresponding to an output index of the weight data w, wherein N, M, i, and w are integers.
