PROGRAMMABLE PROCESSOR SYSTEM WITH TWO TYPES OF SUB-PROCESSORS TO EXECUTE MULTIMEDIA APPLICATIONS

摘要

One embodiment of the present invention includes a heterogenous, high-performance, scalable processor having at least one W-type sub-processor (74, 76) capable of processing W bits in parallel, W being an integer value, at least one N-type sub-processor (78, 80) capable of processing N bits in parallel, N being an integer value wherein and smaller than W by a factor of two. The processor further includes a shared bus coupling the at least one W-type sub-processor and at least one N-type-sub­processor and shared memory coupled to the at least one W-type sub-processor and the at least one N-type sub-processor (312), wherein the W-type sub-processor rearranges memory to accommodate execution of applications allowing for fast operations.
