PROGRAMMABLE AND PARALLEL VARIABLE-LENGTH DECODER FOR VIDEO SYSTEMS

In this paper, we propose a parallel and programmable VLC decoder whic h includes the arithmetic representation of codewords, codeword regula rity, and its hardware configuration. With the proposed hardware confi guration, the parallel VLC decoder is faster and with less memory than the traditional decoder. Furthermore, the programmable VLC decoder, w hich can decode more codewords in one clock, can be devised by extendi ng the parallel concept.
