符合OpenGL标准的国产化显卡研究与实现

我国现有显卡设计基本依赖国外产品,没有统一的软硬件接口,导致显示性能不高、显示软件升级和移植困难。OpenGL（ Open Graphics Library）以其强大的功能、性能及良好的兼容性成为业界广为使用的图形API接口。文中基于对OpenGL标准的深入分析,介绍了一款基于OpenGL 1.3标准的显卡设计与实现方案。该显卡与主机采用PCI总线互联,核心图形处理功能基于FPGA,采用专用硬件处理逻辑与软件结合的方式实现,可完成二维/三维硬件加速功能。经过测试和验证,该显卡可替代以ATI M9-CSP64芯片为核心的显卡。

Research and Implementation of Domestic Video of OpenGL Standard

In domestic market,the design of the existing video card is basically dependent on foreign products,there is no unified hardware and software interfaces,which makes display performance is not high,the display software upgrading and migration difficult. OpenGL is widely used graphics API interface with its powerful functions,performance and good compatibility. Based on the analysis of OpenGL standard,introduce a scheme of design and implementation of a video card based on OpenGL1. 3 standard. The card is connected to a host with PCI bus,the key graphic function is based on FPGA,in the way of combining the special hardware processing logic and software,to be completed 2D/3D hardware acceleration. After testing and verification,the card can replace the video card used ATI M9-CSP64 as its core.
