Title:
SIGNAL PROCESSING DEVICE, IMAGING DEVICE, AND SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/070947
Kind Code:
A1
Abstract:
A signal processing device is configured so as to comprise a multiply-accumulator that is positioned in the form of a one-dimensional or two-dimensional array and that is capable of carrying out multiply-accumulate operations in a neural network, a threshold value assessment processing unit for assessing whether or not input data used for computation by the multiply-accumulator is less than a prescribed threshold value, and an avoidance processing unit for causing multiply-accumulate operations on the input data to be avoided when the input data is less than the prescribed threshold value.
