3D图形API(Application Programming Interface,应用程序编程接口)是三维图形处理函数接口的简称,它将图形系统的上层应用程序和底层驱动隔离,使得应用软件具有良好的可移植性。 OpenGL( Open Graphics Library,开放图形接口库)是为了规避不同硬件驱动而定义的与上层接口的标准库函数。如何开发出符合OpenGL标准的API,是3D图形处理器研制及应用的关键。首先系统分析了OpenGL标准API的属性,提出了自研3D图形处理器API与OpenGL标准API符合性验证关键技术,基于FPGA平台从函数的接口参数、绘图功能、显示功能和错误反馈处理这四个方面来验证。上述验证方法具有很强的操作性,验证覆盖范围更广,验证用例的设计更为复杂。该方法加速了验证过程,提高了验证的充分性。

3D graphic API ( Application Programming Interface) is an abbreviation of 3D graphic processing function API. In order to make the application transplantable smoothly,it separates top application from bottom drivers in graphic system. OpenGL ( Open Graphics Library) is defined to avoid different hardware drivers. How to develop the API which accords with OpenGL standard is the key point for research and application of 3D graphic processor. First analyze the attribute of OpenGL API,put forward the key technology for verifying self-researched API and OpenGL standard API. Verification is conducted from functional interface,drawing function,display function and error feedback on the basis of FPGA platform. The above method is easier to operate,more extensive coverage,more complex verifying examples. This method can accelerate the verifying process and improve the sufficiency of verification.
