Title:

MULTI-PRECISION ACCELERATOR BASED ON SYSTOLIC ARRAY AND DATA PROCESSING METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2023/092669

Kind Code:

A1

Abstract:

Disclosed in the present invention are a multi-precision accelerator based on a systolic array and a data processing method therefor. The method comprises: obtaining data precision of preset input data, wherein the data precision is used for representing the number of data bits; determining segment data corresponding to the input data according to the data precision and the input data; and mapping the segment data to a multiplier unit group, and performing multiply-accumulate operation on the segment data by means of a multi-precision accelerator. According to embodiments of the present invention, different pieces of segment data are determined according to the data precision of the input data, then the segment data is mapped to the multiplier unit group, and the segment data is subjected to multiply-accumulate operation by means of the multi-precision accelerator, such that the multiply-accumulate operation of higher throughput can be realized with less memory bandwidth consumption.
