Abstract

The present application relates to a data compression and decompression device and a data decompression method, which can decompress n input data streams in parallel, and set FIFO memories at both the input and output ends to perform synchronous operations on the input data streams and the output decompression results, It is ensured that when multiple data streams of the data to be compressed are compressed in parallel, or when the compressed data is decompressed, the output result is accurate.

Description

technical field [0001] The present application relates to the field of computer technology, and 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, improving its transmission, storage and processing efficiency, or reorganizing data according to certain algorithms to reduce data redundancy and storage space without losing useful information. a technical method. [0003] However, the traditional data decompression method has the problem of low efficiency when decompressing data. SUMMARY 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 response to the above technical problems. [0005] A data compression and decompression device, comprising: a data division circuit, and n compression and decompr...
