An 81 MHz, 1280 /spl times/ 720pixels /spl times/ 30frames/s MPEG-4 video/audio CODEC processor

A high-definition MPEG-4 CODEC processor capable of encoding 720p images (1280/spl times/720 pixels 30f/s) at 81MHz is presented. The CODEC is implemented with only 390k gates and an 80 kB SRAM. It is fabricated in a 0.13/spl mu/m CMOS process on a 5.6mm/spl times/5.6mm die.
