A Highly Efficient VLSI Architecture for H.264/AVC CAVLC Decoder

In this paper, an efficient algorithm is proposed to improve the decoding efficiency of the context-based adaptive variable length coding (CAVLC) procedure. Due to the data dependency among symbols in the decoding flow, the CAVLC decoder requires large computation time, which dominates the overall d...
