Abstract

Embodiments of the present invention provide a system and method for data compression. The system includes: a preprocessing module, used for acquiring compression information of each data block in N data blocks; a management module, used for according to the preprocessing The compression information of each data block obtained by the module determines resource allocation information, and the resource allocation information includes N target parallelisms corresponding to the N data blocks one-to-one; Allocate information to generate N compression processors. The embodiments of the present invention can dynamically adjust the parallelism of the compression processors for data blocks to be compressed with different compression information, so that the parallelism of the multiple compression processors generated by the compression module can further improve the system compression speed under the condition of satisfying the system compression speed. Therefore, the embodiments of the present invention can flexibly and quickly implement data compression.

Description

technical field [0001] The present invention relates to the communication field, and more particularly, to a data compression system and method in the communication field. Background technique [0002] With the continuous growth of data volume and data generation speed, data storage and analysis put forward higher performance requirements for data compression. On the one hand, data compression can significantly reduce the storage space of data on the disk; on the other hand, data compression can reduce the bandwidth requirements for data transmission in the network and data analysis system. [0003] Among many data compression algorithms, LZ77 provides a lossless data compression algorithm based on dictionaries, and has become the basis of most LZ algorithm variants such as LZW, LZSS, etc. and some other compression algorithms. For byte strings that have already appeared, LZ77 replaces repeated occurrences with a "distance-length" pair pointing to its matching byte string. ...
