Abstract

The present application relates to a data compression and decompression device and a data compression method, which can realize the shuffling of the input original data stream, and can overcome the large difference in the compression efficiency of the data in the original data stream of each compression and decompression operation execution component. The execution time of each compression and decompression operation execution component varies greatly, which reduces the problem of data compression efficiency.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data compression and decompression device and a data compression method. Background technique [0002] Data compression refers to reducing the amount of data to reduce storage space without losing useful information, improving its transmission, storage and processing efficiency, or reorganizing data according to a certain algorithm to reduce data redundancy and storage space. a technical method. [0003] However, traditional data compression methods have the problem of low efficiency when compressing data. Contents of the invention [0004] Based on this, it is necessary to provide a data compression and decompression device and a data compression method for efficiently decompressing data in view of the above technical problems. [0005] A data compression and decompression device, comprising: a data shuffling operation execution component, n compression and dec...
