Abstract

A neural network convolution operation device and method, wherein the device is used to realize the convolution operation of the weight matrix and neurons in the neural network in the form of matrix multiplication, which includes: a shift operator, used for the neural network The element matrix and the weight matrix are respectively subjected to winograd transformation to obtain a transformed neuron matrix and a transformed weight matrix; a matrix multiplication operator is used to multiply the transformed neuron matrix and the transformed weight matrix matrix multiplication operation to obtain a multiplication matrix; the shift operator is also used to perform winograd inverse transformation on the multiplication matrix to obtain a convolution operation result; the controller is used to control the shift operator to perform winograd transformation or The winograd inverse transform is also used to control the matrix multiplication operator to perform matrix multiplication.

Description

technical field [0001] The present disclosure relates to the technical field of artificial neural networks, in particular to a neural network convolution operation device and a neural network convolution operation method. Background technique [0002] Multi-layer artificial neural networks are widely used in the fields of pattern recognition, image processing, function approximation, and optimization calculations. In recent years, multi-layer artificial neural networks have been favored by academic circles and industry is getting more and more attention. [0003] In order to meet the increasingly high task requirements, the scale of neural networks has become larger and larger. At present, large-scale convolutional neural networks have included hundreds of layers of network layer structures. The resulting problem is that the neural network needs to do more calculations, especially the convolutional neural network. A large number of convolution operations reduce the calculat...
