A DSP engine for an extensible media embedded processor

Abstract

An extension interface for a configurable processor enabling implementation of an application specific programmable DSP is described. A DSP engine for mobile applications with 32-bit dual MAC architecture based on the extension was designed. The engine can also run separately as stand-alone processor decoupled with the configurable CPU core. A test chip was successfully fabricated using 0.13/spl mu/m CMOS technology and has measured 0.23 mW/MHz for random logic of the engine and the core.
