Abstract

The invention provides a dynamic code table generation device and method based on deflate Huffman coding, and the device comprises a code length statistical circuit which is configured to calculate the code length number of each code in to-be-coded data; a minimum coding circuit which is configured to receive the data of the code length statistical circuit and calculate a minimum code corresponding to each code length based on the code length quantity of each code in the data to be coded; and a code table generation circuit which is configured to receive the data of the minimum coding circuit, generate a dynamic code table based on the minimum code corresponding to each code length in the to-be-coded data, and store the dynamic code table in the register. By using the scheme of the invention, the time for generating the dynamic code table can be greatly reduced, the universality of the device can be improved, and the flexibility of the device can be improved.

Description

technical field [0001] The present invention relates to the field of computers, and more particularly to a device and method for generating a dynamic code table based on deflate Huffman coding. Background technique [0002] With the development of the times, people use and obtain data information no longer simply from books, magazines, newspapers, etc. At the same time, with the maturity and development of mobile Internet, 5G, social network, Internet of Things, big data, artificial intelligence (AI), cloud computing, security monitoring and other technologies, all kinds of data are rapidly expanding and becoming larger, showing explosive growth. the trend of. The popularity of 5G is accelerating, and more and more devices and convenient networking conditions have brought unprecedented opportunities to the storage market. With the rapid growth of data volume, the data storage system is constantly challenged. Among all these technologies, cloud computing technology is equi...
