用FPGA实现机载全姿态指示仪图形硬件填充

Graphic Hardware Filling Method Realized by FPGA on Air-borne Electronic Attitude Director Indicator

论述一种基于DSP和FPGA的机载图形显示系统 ,并提出一种新颖的基于FPGA的动态画面的硬件填充方法 在填充操作过程中 ,由DSP完成画面中填充区域边界的标志运算 ,FPGA完成填充画面像素的刷新操作 。

This article discusses a structure of air-borne fast displaying system based on digital signal processing(DSP) and field programmable gate array(FPGA), and introduces a new FPGA-based hardware filling method of dynamic image. In the process of filling image, DSP is used to indicate the boundaries of filling area in the image. Then FPGA is used to fill the area. This method leads to high speed of renewal. Moreover, the time of renewing image does not change with the changing of renewing area.
