摘要
首先分析了现代飞机对EFIS性能提出的新要求,提出了一种新的提高EFIS系统实时性可靠的硬件解决方案,并在该方案的基础上开发了EFIS硬件电路。基于此硬件方案,分析了字符生成和图形填充在提高EFIS系统实时性方面所起的关键作用。通过对几种不同的图形填充与字符生成方法分析比较,得出结论:采用改进的边标志位填充算法,图形、字符分层生成后叠加重构的方法作为EFIS系统的软件算法实现方式。
New demand for EFIS performance by modern fighter plane is analyzed in this paper. A new solution to EFIS real time performance in software and hardware and developed a practical EFIS. The key effect of fill algorithm on EFIS is discussed. The novel algorithm is selected as application by analyzing the graphic character generation performance. The method of edge flag bit fill-algorithm, the graphic and character produce separately, with the overlap and reconstruction technology are verified the valid means to realize the EFIS system.
