摘要
设计了一种针对图像、音频、视频等多媒体数据的处理新型结构的媒体处理器。该媒体处理器由一个通用数字信号处理器及多媒体协处理器构成,其指令集包含了通用的数字信号处理指令及扩展的多媒体处理指令。多媒体协处理器中包含了多个专用于多媒体处理的功能模块,可以加速多媒体处理的进行。该媒体处理器具有强大的多媒体处理能力,可实现对JPEG压缩图像、MP3音频流或MPEG2的MP@ML级别的压缩视频流的实时解码。
A new type of media processor is proposed in the paper aimed at processing picture, audio, video data. The media processor is formed by a digital signal processing （DSP） processor and a multimedia coprocessor and its instruction set consists of common DSP instructions and extended multimedia processing instructions. The multimedia coprocessor consists of several modules to accelerate the processing of multimedia data. The media processor has strong multimedia processing capability. And it can realize the real time procession of compressed JPEG picture, MP3 audio, MPEG2 MP@ML video data.
