摘要
Display device is an important aircraft instrument to give airman swift and precise information. Attitude indicator is a typical picture which consumes more time on generating graphics than other pictures in aircraft cockpit. This paper presents a display device based on ARM. ARM generated and anti-aliased graphics using double frame buffers and overlapped them to input video. A filling algorithm was proposed to decide the color of a pixel in filling area, according to the connection between the pixel and horizon or outline. The display device decided the pixel color without writing the data into buffer. The algorithm reduces memory access and calculation, so the display device could generate an attitude indicator picture in 16.6ms which resolution is 1600x1200.
