摘　　要： 针对视频监控系统实时性要求高运算量大的特点,提出了基于DaVinci技术的嵌入式视频监控系统设计方案。方案利用基于DaVinci技术的TMS320DM6467 ARM+DSP双核处理器,提高了系统性能,缩短了开发周期。ARM核植入嵌入式Web服务器,以UDP协议实时传输视频数据,实现控制模块与监控终端之间的通信。DSP内核视频数据编码算法选用H.264,大大提高了数据编码效率。 In view of the high-volume computing features of real-time video monitoring system, an embedded video monitoring system based on the DaVinci technology is provided. This system makes full use of the TMS320DM6467 ARM ＋ DSP dual-core processing power to improve the system performance and reduce the development cycle. The video data are transmitted from control module to the monitor terminal on UDP protocol using the embedded Web server implanted in the ARM core. In addition, the ARM core with the use of multithreaded task mechanism fully utilizes the system resources and achieves a better control effect. H. 264 video data coding in DSP core greatly enhances the efficiency of coding data. The scalability of this system is increased by the modularization design throughout the development of the entire system.
