Abstract

This paper presents a high-performance VLSI architecture for context adaptive variable length coding (CAVLC) used in the MPEG-4 AVC/H.264 video coding. Instead of only the coarse-grained 8×8 zero block skipping in the previous design, the proposed design implements the fine-grained zero skipping at the 4×4 block level and the individual coefficient level. The implementation with 0.18um CMOS process just needs average 6.88 cycles for one block coding and costs 11.9K gates when working at 100 MHz. This design saves more than half of cycle count and 48% of area cost when compared with the other designs.
