Abstract :
To meet the performance, area and power requirement constraints of H.264/AVC, we propose a hybrid pipeline architecture, and a data reuse mechanism to reduce off-chip memory access. A 4x4 sub-macroblock pipeline architecture is optimized for low power as well as performance. The proposed H.264/AVC decoder architecture can support CIF(352x288) 30 fps videos at 6MHz with 1.8 mW @ 1.65 V, implemented in 0.18 mum technology.
