Aiming at the high requirements of data storage capacity, realtime of display and chip’s process speed in airborne display system, a type of airborne display system has been designed and implemented. FPGA is used as the main development platform in the system, using its rich design resources to achieve the video data by CMOS camera, after interpolation processing, the video’s cache can be realized by SDRAM DDR2. The instrument graphics which needed to be superposed also generates in the process of image processing, final, superposing the instrument graphics to the video and transferring into the display. Through verification, the graphics of instrument, such as attitude direction indicator and the compass, can be superposed on the 60 frames per second video, each pixel size is 16 bit and the video’s maximum resolution is 1920× 1080 in this system.
