Abstract

The invention discloses Huffman encoding equipment. The Huffman encoding equipment comprises: an interface circuit and an encoding scheduler, the dynamic Huffman encoder which is used for generating adynamic encoding length sequence of the to-be-encoded data after receiving the dynamic Huffman encoding instruction of the encoding scheduler; an input buffer memory write controller; the input buffer memory read controller which is used for directly transmitting the to-be-coded data to the output controller after receiving the non-compression instruction, reading the fixed Huffman table after afixed Huffman encoding instruction is received, performing fixed Huffman encoding on the to-be-encoded data based on the fixed Huffman table to obtain a fixed Huffman encoding result, reading the dynamic encoding length sequence after a dynamic Huffman encoding instruction is received, , and performing Huffman encoding on the to-be-encoded data based on the dynamic encoding length sequence to obtain a dynamic Huffman encoding result; and an output controller and an input buffer memory; and different types of Huffman codes can be satisfied, and the flexibility is high.

Description

technical field [0001] The present application relates to the technical field of Huffman coding, and more specifically, relates to a Huffman coding device. Background technique [0002] Big data poses great challenges to the bandwidth of data storage and communication channels, and the importance of data compression is becoming increasingly obvious. Data compression is mainly divided into lossy compression and lossless compression. Lossy compression takes advantage of the fact that humans are not sensitive to certain frequency components in images or sound waves, allowing certain information to be lost during the compression process; although the original data cannot be completely restored, the lost part has little impact on understanding the original image and is Get a higher compression ratio. Lossy compression is widely used in the compression of speech, image and video data. Lossless compression uses the statistical redundancy of data for compression, which can comple...
