Research On GPU Algorithm Simulation Platform Accords With The Standard Of OpenGL

The man-machine interactive performance of the display system is one of the most important indicators that can measure the performance of modern aircraft.It is very difficult to get a well man-machine interactive when drawing simple graphs only by CPU.So adding graphic processing unit(GPU)in the display system can effectively improve the velocity of rendering and the quality of the graphics.GPU and its related hardware and software technology are the foundation and the core of the high performance display system.The algorithm simulation platform is throughout the whole process of GPU simulation,development,testing,application,which is one of the important software development technology in GPU.The quality of the platform will directly affect the success or failure of the GPU development.It is an important job that how to R&D an algorithm simulation platform with high efficiency and high reliability,and can well support for the development and verification of our own GPU.This paper is selected from my internship which is relate to the project "An aircraft display system",and the design focuses on the development of the algorithm simulation platform based on the graphics processors.Firstly,the paper has introduce the composition of airborne display and the demand of the GPU algorithm simulation platform which comes from airborne display system,and then choose the modularized GPU algorithm simulation platform that conforms to the standard of OpenGL after comparing with the present situation of graphics processor development at home and abroad.Secondly,the operation characteristics of OpenGL 1.3 and OpenGL 2.0 and their operation mechanism of the core function library have been analyzed comprehensively,according to which,we can well divide the pipeline stage of algorithm simulation platform,and design a separate data structure under the characteristics of that pipeline stage.It can finish calling all pipeline stage and resource allocation under all resources cost of the pipeline stage,the input and output task designing,and the function identification system,then complete calculation module of the map algorithms through the graphics processor characteristics.Finaly,we test the graphics algorithm that involves all pipeline stage on the simulation platform,and then test on FPGA prototype verification platform using the same algorithm.The result shows that the algorithm simulation platform can support the development and verification of graphics processor effectively,conforming to the development requirements of the airborne display system.By researching the algorithm simulation platform,one of the key software technology to the GPU,this paper provides a powerful tool for the research and development of graphics processor chip and also accumulated knowledge and experience for more advanced GPU development.
