Abstract: Efficient processing of multimedia application is becoming one of the main bottlenecks in media application field, and many architectures have been proposed for multimedia processing. This paper classifies the contemporary processors into three groups based on programmability and evolution process: dedicated media processors, general-purpose processors with media ISA extension and multi-core media processors. An overview of media processor architectures is presented with chip examples, and the future development of media processor architectures is pointed out.

Key words: Media processing, Multimedia extensions, Heterogeneous multiple processor
