| 摘 要： | 介绍了在ARM9平台上实现红外视频的实时显示.CPU处理完一帧或一行视频数据后,发出一个外部中断请求,该中断请求激发一次DMA传输,直接将处理好的视频数据传输给FrameBuffer显示.并采用FPGA硬联逻辑接口,提高了系统的响应速度和视频驱动的效率.

| Abstract: | This paper introduces the real-time display of infrared video on the ARM9 platform.After CPU dealt with the video data of a frame or a line,it issued an external interrupt request,which triggers a DMA transfer,directly transmits the dealt video data to FrameByffer to display.FPGA-based hardware logic interface was used to improve system response speed and video-driven efficiency. |
