摘　　要：本文利用Altera公司的FPGA(Filed programmable gate array)作为主处理芯片,设计并实现了基于OLED(Organic light emitting diode)屏的视频处理系统。该系统主要包括视频图像的采集、处理与显示三个部分,能够接收与ITU656标准兼容的YUV4:2:2格式的视频数据,输出24位并行RGB格式的视频图像,实现分辨率为480×272的OLED屏的视频显示。其中,对于视频数据的高速存储是采用的乒乓缓存技术。整个系统用VerilogHDL编写实现系统各功能模块,获得了较好的显示效果。Altera＇ s FPGA （Filed programmable gate array） as the main processing chip, a video processing system based on OLED screen is designed and realized in this paper, which in- cludes three subsystems in terms of video capture, video processing and video display. The sys- tem can process the YUV 4： 2 ： 2 video data stream which is compatible with the ITU656 stan- dard; output a 24-bit parallel RGB format to display on the OLED（Organic light emitting diode） screen with a resolution of 480 × 272. In the system, the high speed storing ability of the video data is realized by the ping-pong cache technology. Each of the functional modules is achieved by Verilog HDL. The whole system has achieved a better visual effect and some practical value.
