为了满足当前国内军机飞速发展的需求，针对目前机载导航显控系统存在的主要问题，设计了一款基于三星 S3C2440、操作系统采用 VxWorks 的导航显控系统。首先从硬件方面讨论了系统的总体结构，论述了各个模块的工作原理和电路连接方式，分析了系统硬件工作原理；然后从软件方面重点讨论了 WindML 下人机界面程序实现过程中遇到的技术难点，对程序代码进行优化使画面更加流畅，减少了计算量，实时性更强。最后，对显控系统进行初步实验，并给出了实验结果和系统效果图。实验表明，提出的基于 ARM 和 Vxworks 的导航显控系统具有显示直观、使用简便、可靠性高等优点，同时与传统的基于 PowerPC 和 VxWorks 操作系统的方案相比成本较低，具有很高的推广应用价值。

In order to meet the needs of the rapid development of domestic military planes,and in the light of the main problems existing in current airborne navigation display system,a navigation display system is designed based on the Vxworks and ARM S3C2440.This paper discusses the system design in two aspects i.e.hardware and software.In hardware,the working principle of the overall structure is discussed.And then the working principle of each module of the system hardware and circuit of every module connection are argued.At last,the working principle of the hardware system is analyzed.In the aspect of software, discussion is focused on the technical difficulties of WindML hunan machine interface programming.Opti-mizing the program code makes the screen more smoothly,and makes the amount of calculation easily, and more real??time.The results show that the Human Machine Interface of display console is simple and intuitive,user??friendly in operation.And this system is low in cost and is wide in application.
