Title:
NEURAL NETWORK PROCESSING DEVICE, NEURAL NETWORK PROCESSING METHOD, AND NEURAL NETWORK PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/075433
Kind Code:
A1
Abstract:
A convolution neural network (CNN) processing device (1) is provided with: an input buffer (10) for storing an input signal A to be applied to a CNN; a weighting buffer (11) for storing a weighting U; a convolution operation unit (12) which performs a convolution operation including a product-sum operation between the input signal A and the weighting U; a storage unit (16) which stores a table (160) in which an input and an output of a conversion-quantizing process are associated with one another, for a case in which the conversion-quantizing process accepts the operation result of the convolution operation as said input, converts the input value on the basis of a predefined condition, carries out quantization by reducing the bit accuracy of the converted data, and outputs the result; and a processing unit (14) which refers to the table (160) to acquire the output of the conversion-quantizing process corresponding to the operation result of the convolution operation.
