Abstract

The invention provides a two-dimensional convolution implementation method and device. The method comprises the steps: one-dimension processing of two-dimensional input data, wherein two-dimensional input data is expanded into one-dimensional data according to a set dimension; convolution core decomposition, wherein the two-dimensional convolution core is decomposed into independent rows or columns according to the expansion mode of the two-dimensional input data; sub-result calculation, wherein the one-dimensional data is subjected to one-dimensional convolution operation respectively with the decomposed convolution core to correspondingly obtain a plurality of one-dimensional sub-result sequences; and sub-result merging, wherein all corresponding data in the multiple one-dimensional sub-result sequences are merged to obtain and output a final two-dimensional convolution calculation result. The invention further provides a two-dimensional convolution implementation device. According to the method and the device, all two-dimensional data can be converted into one-dimensional data, and two-dimensional convolution operation can be completed through one-dimensional convolution operation, so that the control complexity and the on-chip data routing difficulty are greatly simplified.
