A concurrent memory-efficient VLC decoder for MPEG applications

A high performance variable-length coding (VLC) decoder for MPEG applications is proposed. It has a high throughput and requires a small memory size by using concurrent decoding and maximum likely bit pattern matching. MPEG-2 experimental video data are used to simulate the performance. The throughput can reach up to a 45% improvement over standard techniques and the memory (RAM) size is only 256 words.
