Abstract

The invention discloses a neural-network operation device. The device includes: a sparseness processing unit, which is used for carrying out sparseness processing on a weight matrix to generate a binary sparse sequence, wherein "0" corresponds to an element, of which a numerical value is "0", in the weight matrix, and "1" corresponds to an element, of which a numerical value is not 0, in the transformed weight matrix; a mapping unit, which is used for generating a mapping relationship table of the sparse sequence and element positions in a neuron matrix, wherein a K-th bit of the sparse sequence corresponds to an element of an i-th row and a j-th column in the neuron matrix of M rows x N columns, and it is met that (i-1) x N + j = K or (j-1) x M + i = K; and a controller, which is used forcontrolling the sparseness processing unit to generate the sparse sequence, and controlling the mapping unit to generate the mapping relationship table.

Description

technical field [0001] The present disclosure relates to the technical field of artificial neural networks, and in particular to a neural network computing device and a neural network computing 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 calculation speed of the neu...
