Abstract

A novel media processor aimed at processing picture, audio and video data has been proposed in the paper. The media processor is formed by a digital signal processing (DSP) processor in combination with a multimedia co-processor. The instruction set of media processor consists of common DSP instructions and extended multimedia processing instructions. The multimedia co-processor is made up by several hardware modules which accelerate the processing of multimedia data. The media processor has strong multimedia processing capability and it can realize the real-time decoding of compressed JPEG picture, MP3 audio, MPEG2 MP@ML video data.
