Deep learning processing apparatus and method, device and storage medium

Abstract

Embodiments of the present disclosure propose a deep learning processing apparatus and method, device and storage medium, relating to the field of artificial intelligence. A deep learning processing apparatus includes: at least one matrix multiply-add module, configured to perform a matrix multiply-add operation of a convolution kernel parameter value matrix of a convolutional layer in a convolutional neural network and a first error gradient value matrix to obtain a plurality of intermediate matrices; a storage apparatus, configured to store the plurality of intermediate matrices without reshaping elements in the plurality of intermediate matrices; and a plurality of matrix accumulation modules, configured to read the plurality of intermediate matrices from the storage apparatus and perform a matrix accumulation operation based on the plurality of intermediate matrices according to a convolution scheme of the convolutional layer in parallel, to obtain a second error gradient value matrix for the convolutional layer.

Dependencies are inferred from the claim text.
