A H.264/MPEG-2 dual mode video decoder chip supporting temporal/spatial scalable video

摘要

This paper proposes a dual mode video decoder with 4-level temporal/spatial scalability and 32/64-bit adjustable memory bus width. A design automation environment for simulation and verification is established to automatically verify the correctness and completeness of the proposed design. Using a 0.13 um CMOS technology, it comprises 439Kgates/10.9KB SRAM and consumes 2~328mW in decoding CIF~HD1080 videos at 3.75~30fps when operating at 1~150MHz, respectively.
