The Research Of Window System Based On Graphic Processor Unit

The performance of the display system is one of the most important Indicator which can measure the performance of modern aircraft.Drawing complex graphics only by CPU is very hard to get a good man-machine interactive.Add GPU into the graphic system can improve the rendering rate and quality of the graphics effectively.GPU and the hardware and software technology related to it is the foundation and the core of the high performance realization of display system.The Window system has throughout the whole process of the GPU simulation, development, testing, application, etc.The quality of it can directly affects the result of the GPU development.How to develop a high efficiency and high reliability window system which is suitable and well support for our own GPU has become a important job in GPU’s research.This ctopic comes from my internship work of "An aircraft display system" project. This design focuses on the development work of window system based on graphics processors. First,it introduces composition of the airborne display system and analyzed the demand of the window system,then after the comparing of several popular window systems,we choose Mini GUI as the window system which we will develop based on the GPU. Second, it analyzed the characteristics of our own GPU, introduces development system hardware and software environment of Mini GUI, and transplant,cutting and optimization Mini GUI on the FPGA prototype verification platform successfully.Thirdly, it built the GLUT/GLU utility library platform which is related to the indow system under Mini GUI.Finaly,we have test the Min GUI and the library related to it on our own GPU’s FPGA prototype verification platform. The results show that Mini GUI can effectively support our own GPU’s performance, and it also conforms to the requirements of the airborne display system. This article has made a solid foundation to the research of GPU through the research of one of the key software technology to the GPU——The Window system based on GPU,and it’s also accumulated knowledge and experience for the development of more advanced GPU.
