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.

[ What is claimed is:] [1.]1. A single integrated circuit comprising:a first data processor having a first set of data processing structures capable of data processing according to a first instruction set; anda second data processor having a second set of data processing structures different from said first set of data processing structures capable of data processing according to a second instruction set different from said first instruction set;wherein said first and second data processors are capable of independent operations on disjoint instructions and data sets.
