机载电子综合显示系统对图形算法的准确性、快速性要求较高,通用的图形处理系统往往不适用;针对机载图形中最耗时的全姿态指示仪,提出一种基于FPGA的硬件生成系统;该系统预测地平线各像素行的像素点数量,使用水平线扫描线进行填充,并在填充的过程中适时的计算轮廓和地平线上坐标;减少了计算量,简化了帧存总线的设计,通过硬件加速提高了图形的生成速度,有效地实现了全姿态指示仪的图形生成。 Airborne integrated electronic display system has high accuracy and rapidity of the graphic algorithm, and the general graphic processing system is not suitable for the most. In view of the most time-consuming full-attitude indicator in airborne graphics, a FPGA-based hardware generation System. The system predicts the number of pixel points in each pixel line of the horizon, uses the horizontal line scan line to fill, and calculates the contour and horizon coordinates timely in the process of filling; reduces the calculation amount, simplifies the design of the frame memory bus, Hardware acceleration improves the speed of graphics generation and effectively realizes the graphics generation of the full attitude indicator.
