直线生成算法在飞机座舱全罗盘画面绘制中的应用

Optimized Algorithm for Generating Line Segment in Airborne Compass Display

摘要: 从Bresenham直线生成算法和两步算法入手,在对这两种直线生成算法改进的基础上,提出把算法的优化与所用的微处理器和编译系统结合起来,探讨进一步提高算法效率的途径.并在研制的飞机座舱显示系统全罗盘画面的绘制中给出具体实现,给出与前两种算法的执行时间比较.

Abstract: The Bresenham and Double-Step algorithm are further improved with ADSP21060 Visual 2.0++ compiler and the rendering speed of line segments is increased by 44% and 45%, in comparison with the original Bresenham algorithm and Double-Step algorithm.
