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. Such deep learning processing apparatus may significantly improve the calculation efficiency of the convolution inverse operation, improve the calculation speed and reduce the power consumption.
