设计并实现了一种基于ARM+FPGA的视频监控系统,以ARM9处理器为主控制器,FPGA为协处理器,构造ARM与FPGA间的高速数据传输通道和基于Linux的轻量级的图形驱动,完成实时视频采集和显示.实验结果表明,该设计能够流畅播放PAL/NTSC两种制式视频信号,具有良好的扩展性、稳定性和较快的响应速度.
A video monitoring system is designed and implemented based on ARM and FPGA. With ARM9 processor as master controller and FPGA as coprocessor, the functions of real-time video acquisition and display are realized on the basis of constructing high-speed data transmission channel between ARM and FPGA and establishing lightweight graphics drivers on Linux OS. The experiment shows that the system can play video fluently which are PAL or NTSC formats with the advantages of excellent expansibility,high stability and fast response speed.
