A low power high performance design for JPEG Huffman decoder

JPEG image codec is one of the most commonly used standards for communication and storage applications. In this paper, we propose a simple and successful design for a JPEG alternating current Huffman decoder with low power and high performance considerations. Based on the parallel Huffman decoder structure, we utilize the bipartition architecture on the lookup table to reduce power consumption without sacrificing decoding performance. Gate level power simulation results show a maximum of 25% power reduction can be obtained when compared with the conventional JPEG parallel Huffman decoder.
