| In the current,GPU is widely used, almost all computers are equipped with a graphicscard, the GPU graphics core. Graphics processor GPU as the basis of3D graphics hardware,computer graphics system or graphics processing demand of electronic products, which playan important critical role that we can not imagine, on the screen to see the colorful graphicsscreen, vivid, high-definition three-dimensional graphics are graphics processor (GPU)technology development to bring visual impact and enjoyment.With the development of embedded technology, computer graphics, the graphics displaytechnology requirements become more and more high, it requires a computer to be able toprovide real-time, high-definition resolution graphics. In the21st century, the application ofembedded devices become more and more widespread, promoting a large extent on thedevelopment of computer graphics, for people to bring3D technology and high-resolutionhigh-performance graphics processing functions. In the the GPU development of history,people have not used GPU so called graphics processor computer handles graphics tasks thanGPU, because it is not the birth before are borne by the CPU with the graphics technologycontinue development, the CPU gradually can not meet the efficient graphics rendering andgraphics computing, in this case, the research and design of embedded graphics processorGPU, has an important role in China’s social development and the progress of history.From the calculation graphics development direction, as well as the circumstances of thesituation in China and abroad if a systematic comparison, this topic design a GPU ofindependent intellectual property rights, choose to use standard is OpenGL ES1.0, OpenGLES1.0has a lot of features, One of the main characteristics is that it is completely free andcross-platform, it is2D3D graphics API standard interface, so I chose this standard is quiteideal.First, this paper analyzes the graphics processor’s history of the development, and nowthe development of the situation and the future prospects, and then analyze the composition ofthe graphics system’s hardware and software and graphical display software and hardwareaccelerated rendering process, proposed hardware design and software of the graphicssystemdevelopment thinking. In this paper, on the basis of the overall design of the systemcomponents graphics and embedded graphics processor GPU program, focuses on the twoGPU graphics processor engine is how to design, these two engines is the geometry engineand rasterization engine. The design of the graphics pipeline is the core of the entire graphics acceleration chip design, so this paper is to analyze the processing of graphics processorsgraphics around the the image pipeline’s flow process, analysis of graphics processing meansand the derivation of the mathematical algorithms.Finally, the graphics processor validation software library functions, these featuresinclude graphics translation, rotation, scaling, illumination, cutting, removed, projection,rasterization function, Realized the graphics processor chip function simulation software. |
