摘要
飞机座舱显示系统是航空电子系统的重要组成部分,以DVI为代表的高清信号越来越多地应用在航电显控系统中。与传统的符合DVI1.0标准的单链路DVI信号相比,双链路DVI信号传输频宽是其2倍,可以呈现出超大分辨率的视频影像,最高显示可达2 560×1 600@60 Hz。提出一种基于FPGA的双链路DVI信号设计,可以实现将两路单链路DVI信号转换成一路超大分辨率的双链路DVI信号进行传输。
Cockpit display system is an important part of avionics system. More and more high definition signals such as DVI are used to transmit video signals. Traditional DVI1.0 is single link and its bandwidth cannot satisfy the transmition requirement. Meanwhile, the bandwidth of dual link DVI is double of single link DVI and dual link DVI can transmit high resolution of 2 560x 1 600@60 Hz for displayer. This paper presents a method of dual link DVI circuit design based on FPGA, which can convert two channel single link DVI to one channel dual link DVI. With the presented method, high resolution video signals can be transmitted to displayer and satisfy the requirement of avionics system.
