异构双核处理器的嵌入式视频监控系统研究

Research of Video Surveillance System Based on Heterogeneous Dual-core Processor

基于嵌入式视频处理新技术——达芬奇技术,重点研究了xDM多媒体算法标准、编解码引擎、编解码服务器等理论。以搭载异构双核处理器OMAP3730的开发板为硬件平台,ARM端配置视频编解码引擎,DSP端配置视频编解码服务器,使得系统能在ARM上进行控制操作,在DSP上进行H.264视频编解码。最后在Linux上完成上层应用的编写。

Based on the new technology of embedded video processing,DaVinci technology,this paper researches on the xDM multi media algorithm standard,codec engine,codec server,etc.Beagleboard is used as the hardware platform which equipped a heterogeneous dual-core processor OMAP3730.The codec engine is configured on the ARM subsystem and codec server is configured on the DSP subsystem.The whole system is controlled by ARM subsystem.The DSP subsystem achieves the H.264 codec.Finally,the system application is coded on the Linux OS.
