摘　　要：详细讨论了OMAP架构的双核通信机制,分析了Codec Engine,DSPlink,CMEM等核心模块。然后实现了一种基于OMAP3530开发平台的AVS视频解码系统,实现了ARM处理器接收网络数据和显示图像,DSP处理器解码AVS码流。在Linux环境下将AVS视频解码器移植到3530开发板中,在分辨率D1下达到25 f/s(帧/秒)。In this paper, dual-core communication mechanism of OMAP architecture is discussed in detail and such core modules as Codec Engine, DSPlink, CMEM and so on are analyzed. Then an AVS video decoding system based on OMAP3530 development platform is achieved, which implements receiving network data and displaying images on ARM processor and decoding AVS code stream on DSP processor. The AVS video decoder is transplanted to 3530 development board under Linux environment, reaching 25 f/s under DI reselution.
