Implementation of a fast MPEG-2 compliant Huffman decoder

In this paper a 100 Mbit/s Huffman decoder implementation is presented. A novel approach where a parallel decoding of data mixed with a serial input has been used. The critical path has been reduced and a significant increase in throughput is achieved. The decoder is aimed at the MPEG-2 Video decoding standard and has therefore been designed to meet the required performance.
