ABSTRACT:
A single integrated circuit includes first and second data processors operating on different instruction sets independently operating on disjoint programs and data. The single integrated circuit preferably includes an external interface, a shared data transfer controller and shared memory divided into plural independently accessible memory banks. The two data processors are preferably a digital signal processor (DSP) and a reduced instruction set computer (RISC) processor. The DSP and RISC processors are suitably programmed to perform differing aspects of computer image processing.
