Design and Research on VGA Display Interface Based on ARM Embedded System

Advanced RISC Machines(ARM)Embedded system implementing display function of Video Graphics Array(VGA)display interface,involved in construct of timing signal and image data digital-to-analog(D/A)converting.Through the research on S3C2410 Liquid Crystal Display(LCD)controller with ARM920T CPU core and high speed D/A converter,a design scheme of VGA display interface is presented.Method of digital image data D/A converting and output to VGA interface display is given,which include hardware design,construct VGA timing signal,control of video D/A converter.A system soft design of VGA display interface is introduced in the end.This method achieves the intention of ARM Embedded system implementing display function of VGA display interface,uses less system resource,plays in high performance and reliability,thus it can meet the demands of real-time display.
