飞机座舱综合图形显示系统设计的一种新方法

针对飞机座舱图形显示的特点，本文提出了一种高速帧存结构和可重构协处理器的设计方法。该高速帧存结构具有自动消隐和背景颜色可编程的功能，所设计的基于FPGA技术的可重构协处理器能在系统动态改变其所实现的算法。这些方法大大减少了处理器的工作量，提高图形生成和显示速度，解决了在图形显示中的速度瓶颈。文中具体介绍了该系统组成结构和设计方法。

A New Design Method of Combined Graphics Display System in Aircraft Cockpit

According to the feature of the graphics display system in the aircraft cockpit,a new system structure of high speed graphics frame buffer and a design method of reconfigurable co processor are presented. This frame buffer has the ability of automatic vanishing and can set the background color, moreover, and the reconfigurable co processor based on FPGA can dynamically change itself so as to realize different algorithms during the system running. Both new design methods can reduce the burden of processor, improve the speed of graphics generation, display and solve the bottleneck of speed in the graphics display. The system structure and the design methods are presented in detail.
