Title:
DATA COMPRESSION STORAGE SYSTEM AND METHOD, PROCESSOR, AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/237513
Kind Code:
A1
Abstract:
A data compression storage system and method, a processor, and a computer storage medium, used for compressing a feature map in an on-chip memory and then storing same in an external memory. The system comprises: a compression command generating module is used for distributing compression commands to each of at least two compression paths; each compression path is used for reading a corresponding original feature map from an on-chip memory on the basis of the compression command and compressing same; a read arbitration module is used for performing arbitration on read feature map commands of the at least two compression paths; and a write arbitration module is used for performing arbitration on write requests of the at least two compression paths. Thus, the system enables compressed data to occupy less storage space, reducing the space occupation of the external memory and also reducing bandwidth resources during read/write, saving power consumption. In addition, the data compression is performed in parallel by at least two compression paths, increasing compression efficiency.
