基于国产GPU的机载座舱显示系统设计与实现

Design and Implementation of Airborne Cockpit Display System Based on Domestic GPU

基于新一代飞机座舱显示系统在信息交互能力、芯片处理速度、系统可靠性等方面的高要求,设计并实现一款具备综合显示功能的机载座舱显示系统。系统以国产图形处理器为核心,可实现视频生成、图形参数计算及显示等功能;同时采用国产CPU作为控制处理器,进行数据处理、逻辑判断等操作;将最终数据通过LVDS编码格式进行视频输出。经测试,系统可将数据信息以数字、字符、图形及其组合的形式呈现在显示屏上,获得良好的效果,可为实现装备国产化与信息安全化提供助益。

Based on the high requirements of the new generation aircraft cockpit display system in terms of information interaction ability,chip processing speed and system reliability,an airborne cockpit display system with comprehensive display function is designed and implemented.The domestic graphics processor is the core of the system,which can realize the functions of video generation,graphic parameter calculation and display.At the same time,the domestic CPU is used as the control processor for data processing,logic judgment and other operations.The final data is video output through LVDS coding format.After testing,the system can display the data information on the display screen in the form of numbers,characters,graphics and their combinations,and obtain good results,which can provide help for the localization of equipment and information security.
