Title:
DATA PROCESSING DEVICE, DATA PROCESSING PROGRAM, AND DATA PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/248309
Kind Code:
A1
Abstract:
A data processing device 1 with a minimum precision of N bits for convolution operations performs a convolution operation on two pieces of input data with a width of 2M×N bits (N is a positive integer and M is an integer equal to or larger than 0), and performs minimum-precision product-sum operations when performing a plurality of consecutive processes corresponding to the integer M. If the value of the integer M is not 0, the data processing device 1 performs shift operations on the results of the minimum-precision product-sum operations while performing sign operations in the convolution operation on the input data, reflects a sign, which has been held until a reset signal is received, in the outputs of the shift operations according to the value of the integer M, and calculates a cumulative sum of the outputs of the shift operations with the reflected sign.
