Abstract

The invention relates to a data compression and decompression device and a data decompression method. n input data streams can be decompressed in parallel, FIFO memories are arranged at an input end and an output end respectively, synchronous operation is conducted on the input data streams and an output decompression result, and it is guaranteed that the output result is accurate when multiple data streams of the to-be-compressed data are compressed in parallel or the compressed data are decompressed.

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 decompression 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, the traditional data decompression method has the problem of low efficiency when decompressing 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 division circuit, and n compression and decompression ...
