Abstract

This paper discusses a hardware accelerated implementation for PNG image decoding within LZ77 and Huffman compression algorithm without any distortion, while compare with software decoding, parallel processing is the most significant feature of high efficiency. This design utilize cooperating of software and hardware to solve the problem of controlling hardware decoder, extend Deflate algorithm of Huffman tree to achieve fast look up, so it can improve decode efficiency with lower power consume.
