Abstract: The virtual graphics processor is a software process that enables different video display systems to execute the same graphical display application. The process also permits the display application to be updated or reconfigured in real time without changing the embedded display system software. The parts of the virtual graphics processor include an application graphics database for storing graphic primitives and associated static primitive data defining one or more graphic pages in a display application. An image control interface (video library) associates graphic functions of the particular video display system with graphic primitives in a requested page. An instruction sequencer within the virtual graphics processor responds to a display request by obtaining the requested graphic page from the graphics database and associated graphics functions from the video library. The addresses of the graphic functions and associated data for the graphic page are passed from the instruction sequencer to an instruction queue. A graphics logic unit reads the addresses from the queue and calls the function, providing each called function with the associated data. The display system responds to the called graphics functions by displaying the requested page with its associated data on a video screen.

Abstract translation: 虚拟图形处理器是一种软件过程，可使不同的视频显示系统执行相同的图形显示应用程序。 该过程还允许实时更新或重新配置显示应用程序，而无需更改嵌入式显示系统软件。 虚拟图形处理器的部分包括用于存储在显示应用中定义一个或多个图形页面的图形原语和相关联的静态原始数据的应用程序图形数据库。 图像控制接口（视频库）将特定视频显示系统的图形功能与请求的页面中的图形基元相关联。 虚拟图形处理器内的指令定序器通过从图形数据库获得所请求的图形页面和从视频库中的相关联的图形功能来响应显示请求。 用于图形页面的图形功能和相关数据的地址从指令定序器传递到指令队列。 图形逻辑单元从队列读取地址并调用该函数，为每个被调用的函数提供关联的数据。 显示系统通过在视频屏幕上显示其所关联的数据的所请求的页面来响应所调用的图形功能。
