Abstract :
A DSC/DV dual role backend integrated controller chip is presented. It is an integrated SoC that includes hardwired image processing module, JPEG/MPEG-4 SP codec engine, 32-bit RISC engine, and other audio, video, and USB mixed signal interfaces. The key design breakthrough is to merge JPEG and MPEG-4 into a single codec module where DCT and quantization functions are shared between still and video coding process. It can achieve real-time MPEG-4 compression for VGA video at 30fps at only 96MHz speed.
