摘要
文中研究Xilinx Zynq平台的ARM+FPGA体系结构,提出一个基于ZYNQ芯片的软硬件协同工作的实时视频处理系统。该系统采用ARM处理器进行图形界面程序开发,实现任务调度;通过Vivado HLS工具进行图像处理算法开发,实现在DDR缓存上的数据交互。测试结果表明,这种基于ARM+FPGA的软硬件协同处理系统使视频处理速度获得了很大的提升,满足实时性的要求。
The ARM+FPGA architecture of the Xilinx Zynq platform is studied,and a hardware and software co-processing real-time video processing system based on the ZYNQ chip is proposed in this paper.In the system,the ARM processor is used for the graphical interface program development,so as to realize task scheduling.The image processing algorithm is developed by using the Vivado HLS tool,which is integrated into the FPGA IP core to achieve the hardware acceleration processing.The data interaction in the DDR cache is realized by using the Xilinx Vdma IP.The test results show that the hardware and software co-processing system based on the ARM+FPGA can significantly improve the video processing speed,'which satisfies the realtime requirement.
