CNN processing equipment, CNN processing methods, and programs

摘要

PROBLEM TO BE SOLVED: To provide a CNN processing apparatus, a CNN processing method, and a program capable of reducing the amount of calculation as compared with the conventional case. A CNN processing device includes a kernel storage unit that stores a kernel used in a convolutional operation, a table storage unit that stores a Fourier basis function used in a convolutional operation, and a k-th kernel in a CNN (convolutional neural network). Coefficient Gk (k, m) (k is any integer between 1 and K, K is the number of kernels, m is any integer between 1 and M, M is the total number of pixels of the kernel) The elements gk and m in the above are modeled by N (N is an integer of 1 or more) next Fourier series expansion, and the processing target information, which is the processing target information, is convolved by the CNN method using the kernel and the Fourier base function. It is provided with a convolutional calculation unit that performs [Selection diagram] Fig. 2
