FPGA上的硬件Video Port设计

Video port design based on FPGA

提出一种适合FPGA实现的视频输入输出系统结构。该系统包括视频图像采集、视频图像存储和视频图像显示三个部分。视频采集部分能够接收符合ITU-RBT.656标准的PAL格式YUV视频流数据;视频图像显示部分能够输出标准VGA格式的视频图像。该系统结构在XilinxFPGA上实现并取得了较好的效果。

This paper proposes an architecture of FPGA based video port. The architecture is composed of three subsystems, which are video capture, video storage and video display subsystems. The video capture subsystem can process YUV video stream that is compatible with the ITU-R BT. 656 PAL standard, while the video display subsystem can display the image in standard VGA format. The whole system has been implemented on Xilinx FPGA, and achieves good result.
