Abstract :
A high-speed context-based adaptive variable length coding (CAVLC) encoder for H.264/AVC is presented. Since CAVLC scans residues in a block one by one to obtain the statistics of the data to be encoded, it requires a large number of cycles. In the proposed scheme, two residues are scanned in one cycle to reduce scanning time by half.
