基于DSP视频监控系统中的优化设计
首发时间:2011-05-09
摘要:现在随着视频监控系统的不断发展,越来越多的视频监控设备开始向着轻、巧、小的方向不断完善。其中基于嵌入式的视频监控系统以其能适应不同复杂环境的高稳定性,监控的实时性,能有效跟踪目标等优点而得到了广泛的应用。对整个系统的程序代码进行了相应优化改进。对部分C语言进行了改进优化,使用EDMA进行内存优化。对其中部分的图像处理以及运动目标跟踪等相关算法使用标准汇编,进行汇编优化,从而降低了图像算法的计算时间,提高了系统的执行效率,并给出了部分的汇编优化的实验对比结果。

Video monitoring system based on DSP the optimization design
Abstract:Iwith the continuous development of video monitoring system, more and more video monitoring equipment starts toward to the direction of more light, chocolate, and small continuously improved. And the video monitoring system based on embedded, with its can adapt different complex environment of high stability, monitoring of real-time, can track the target advantages effectively, has been widely used. Program code of the whole system was optimized and improved accordingly. On the part of the C language has been improved optimization, the use of EDMA for memory optimization. Some image processing and target tracking algorithms used standard assembly to optimize the code, which reduces the image of calculation time, improve the algorithm of the system, and gives the experiment part compared results of the efficiency about the assembly optimization.
Keywords: Control technology embedded system DSP Optimization
