摘　　要：本文在ADI公司双核数字信号处理芯片ADSP-BF561的基础上完成了目标跟踪模块的设计与编程实现。该模块可以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、预处理和跟踪。其中,视频编解码分别采用ADV7171,ADV7181B芯片实现。软件设计上,使用双核工作模式、基于描述子的输入输出模式以及MDMA数据搬移方式着重解决了图像跟踪系统所需的实时性问题。该设计结构紧凑,成本低廉,可靠性高。试验结果显示,所设计的目标跟踪系统能够满足系统的实时性要求。An implementation of target tracking system based on ADI dual core digital signal processor ADSP-BF561 is introduced. 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 target tracking .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 dual – core work mode ,descriptor -based DMA transfers and MDMA .Finally,the result shows that the design can process the video information effectively and correctly.
