摘　　要：有效处理多媒体应用正成为媒体应用领域最主要的瓶颈之一,目前已有多种针对媒体应用的处理器结构。该文根据媒体处理器结构的可编程性和发展过程,把媒体处理器分为3类:专用结构处理器,带媒体扩展指令的通用处理器和多核处理器。结合典型芯片对各种处理器结构进行了分析和综述,指出了媒体处理器结构的发展趋势。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.
