摘　　要：基于ADSP-BF561的结构特点,提出了图像平移系统的设计与实现方案。该设计分为硬件和软件两部分。硬件设计上,以ADSP-BF561为核心,控制视频信号的采集、预处理和平移。其中,视频编解码分别采用ADV7171,ADV7181B芯片实现。软件设计上,分别使用基于描述子的数据传输方式、DMA和MDMA数据搬移方式,着重解决了图像平移时的实时性问题。试验结果证明了该设计的有效性。The design of video translation module based on the structural characteristics of ADSP-BF561 is presented according to the design requirement. The system can be divided into two parts （hardware and software design）. ADSP-BF561 is the core of the system to control the collection, processing and translation of the video signal. The decoding and encoding of the video signal are realized by ADV7181B and ADV7171 separately. In the design of software, it solved cruces such as real time by using of descriptor-based DMA transfers, DMA and MDMA. Finally, the results show that the design can process the video information effectively and correctly.
