Title:
CONVOLUTION CALCULATION DEVICE AND METHOD, PROCESSOR AND MOVABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/155044
Kind Code:
A1
Abstract:
A convolution calculation device (400) and method, a processor and a movable device. The device (400) comprises: an array of multiply-add units (410), comprising M rows and N columns of multiply-add units, a specific multiply-add unit among the M rows and N columns of multiply-add units being used for multiplying a feature value inputted into the specific multiply-add unit and a weight value corresponding to the specific multiply-add unit, adding the resulting product and a previous multiply-add output result, and outputting the resulting sum as an output result of the specific multiply-add unit; and an array of accumulate units (420), comprising one row of N accumulate units, the N accumulate units respectively corresponding to N columns of the array of multiply-add units (410), and a specific accumulate unit among the N accumulate units being used for adding an output result of the last multiply-add unit of a column corresponding to the specific accumulate unit to a previous accumulate output result, and outputting the resulting sum as an output result of the specific accumulate unit. The described technical solution may improve the efficiency of convolution calculation.
