摘　　要：采用基于TI公司高性能Davinci系列的SEED-DTK_6437作为主要硬件平台,实现TMS320DM6437与TMS320VC5402处理器之间的通信。在DSP集成开发环境CCS3.3中采用C语言和汇编语言混合编程,对摄像头采集到的实时视频图像实现了变倍算法从软件到硬件平台的移植。同时加入人机接口,实现了系统缩放倍数的切换、变倍算法的选择和感兴趣区域的提取等功能。测试结果表明,系统具有交互性强、性能稳定和实时性良好等特点。The video image electronic zooming system is mainly composed of TI＇s high-performance Davinci series SEED- DTK 6437 as the main hardware platform, the communication between TMS320DM6437 and TMS320VC540 processors was achieved. Using mixed C and assembly language programming and implemented in DSP integrated development enviromnent CCS3.3. Succeed- ed in transplanting the zooming algorithm from software to hardware platform completely for the camera collected real-time video image, also add to human machine interface.The system magnification switching, zooming algorithm selection, and the extraction of the region of interest was achieved. The result shows that system has strong interaction, stable performance and strong real-time.
