Integrated digital signal processor for parallel asymmetric processing of video and audio multi-media

摘要

The integrated digital signal processor has a general purpose processor (210) and a vector processor (220) for operating in parallel with the general-purpose processor. The general-purpose processor has a set of scalar registers, an instruction decoding unit and an instruction processor (200). The vector processor has a set of vector registers and a second instruction decoder and processor. A cache memory (20) is coupled to the general-purpose processor and to the vector processor. The cache memory has simultaneous read and write ports, and holds a data queue coupled to both processors.
