目前，在很多嵌入式系统的设计中需要将图像数据转换成视频信号在终端上显示，这就需要设计一个基于嵌入式系统的视频显示接口，以便把图像数据转换成适合终端显示要求的信号，并控制其在终端上的显示。由于嵌入式系统便携式的特点，要求视频显示电路不但功能强、性能好，而且体积小、重量轻、功耗低，同时要兼顾性价比。-Currently, in many embedded system design needs to be converted into image data in a video signal displayed on the terminal, This requires a design based on the Embedded System Video Display Interface, so that image data into suitable for the requirements of the terminal display signals, and control of its terminal in the show. As portable embedded system features video display requirements of the functional circuit not only strong, good performance, but also small in size, light weight, low power consumption, taking into account the cost performance.
