The hardware design of a real-time airborne video image processing system is studied in this paper.The system uses the XC5VFX70T FPGA as the core processor to implement the decoding,real-time processing and encoding of video signals of such formats as DVI and PAL.The circuit design of the system is concise,flexible and scalable.The paper introduces the overall hardware architecture of the system.The hardware plans of the decoding module,encoding module and video buffer module are also designed in detail in this paper.The final results of the experiments prove that the system can process the high definition video with 1 600×1 200 resolution,60 frames/s fresh rate,24 bit true color fluently,and the processing time of one frame high definition video is less than 3 ms,which can meet the real-time requirements of the system.

Key words: real-time video image process;embedded hardware design;FPGA
