PARALLEL METHOD AND DEVICE FOR CONVOLUTION COMPUTATION AND DATA LOADING OF NEURAL NETWORK ACCELERATOR

Disclosed are a parallel method and device for convolution computation and data loading of a neural network accelerator. The method needs two input feature maps and two convolution kernel cache blocks, and sequentially stores the input feature maps and 64 convolution kernels into cache sub-blocks according to a loading length, so as to execute convolution computation and simultaneously load data of a next group of 64 convolution kernels.
