Gray prediction decoding algorithm for VLC decoder

研究成果: Paper

摘要

In this paper, a new decoding algorithm for VLC decoder is proposed. In traditional VLC decoding algorithms, we have to search each level of Huffman tree per operation. Therefore the possible throughput is limited by the searching time. The proposed algorithm takes advantage of the trend among AC coefficients in each block to predict the next codeword. From the simulation results, it shows that the prediction mechanism can significantly improve the decoding efficiency.
