A single-chip video signal processing system with embedded DRAM

A programmable single-chip multiprocessor system for video signal processing applications has been developed. It integrates four processing nodes with on-chip DRAM and application-specific interfaces. The embedded DRAM is primarily used as a frame buffer and makes external memory for most applications obsolete. For fast access to local data segments a static RAM is also integrated in each processing node. Methods for efficient usage of the integrated memory are discussed and the concept for a MPEG2 video encoder/decoder implementation is presented
