Title:
COMPUTATION PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/265044
Kind Code:
A1
Abstract:
Provided is a computation processing device that can further reduce power consumption. Element data from within a pooling region is sequentially inputted into a pooling processing unit 22 from a convolution computation unit. The pooling processing unit 22 has a nonvolatile resistor 32, a comparator 33, and a multiplexer 34. The comparator 33 compares the element data from the convolution computation unit with element data stored at the resistor 32. On the basis of the comparison results, the multiplexer 34 selects element data that has a large value, and the selected element data is stored at the resistor 32. After the element data from within the pooling region has been inputted, the element data stored at the resistor 32 is outputted as pooling data. When the pooling processing unit 32 is waiting for input of element data, a PG switch 35 is turned off, and power supply to the resistor 32 is disconnected.
