Abstract
This paper proposes a new method of CAVLC (Context Adaptive Variable Length Coding) encoder design. To achieve best hardware utilization, this function is divided into 8 parts: Stage1, nCBuffer, LevelBuffer, writeSE_LEVEL_VLC, writeSE_Total0, writeSE_0Run, Mux_5to1, and OutputUnit. The memory cost is fewer with smaller buffer and carefully reduced lookup tables.
Besides, the two-stage pipelined structure improves the data throughput. Thus, this design is suitable for the real-time H.264/AVC video encoding/decoding on digital cameras.
