|1. (WO2018108126) NEURAL NETWORK CONVOLUTION OPERATION DEVICE AND METHOD|
|Applicants:||SHANGHAI CAMBRICON INFORMATION TECHNOLOGY CO., LTD
|Title:||NEURAL NETWORK CONVOLUTION OPERATION DEVICE AND METHOD|
A neural network convolution operation device and method, the device being used for implementing a convolution operation of a weight matrix and neurons in a neural network using a matrix multiplication mode, and comprising: a shift operator, used for carrying out Winograd transformation on a neuron matrix and a weight matrix respectively so as to obtain a transformed neuron matrix and a transformed weight matrix; a matrix multiplication operator, used for carrying out a matrix multiplication operation on the transformed neuron matrix and the transformed weight matrix so as to obtain a multiplication matrix, the shift operator also being used for carrying out Winograd inverse transformation on the multiplication matrix so as to obtain a convolution operation result; a controller, used for controlling the shift operator to perform Winograd transformation or Winograd inverse transformation, and also used for controlling the matrix multiplication operator to perform the matrix multiplication operation.
