基于GPU指令转发的虚拟化图形引擎设计及实现

Design and Implementation of Virtual Graphics Engine Based on GPU Instruction Forwarding

为了满足机载座舱显控系统对图形引擎的性能要求,设计了一种基于半虚拟化的机载图形引擎实现方案,并在嵌入式平台上进行实现和测试.结果表明采用本文设计的虚拟化图形引擎,可以满足多个虚拟机同时使用GPU进行绘制的需求的同时,可以有效发挥多核CPU的性能,在提高了产品集成度的同时,显著提升了机载图形应用的性能。

In order to meet the performance requirements of the airborne cockpit display and control system on the graphics engine,an implementation scheme of airborne graphics engine based on para-virtualization is designed,implemented and tested on the embedded platform.The results show that the virtual graphics engine designed can meet the requirements of multiple virtual machines using GPU for rendering at the same time.AT the same time,it can effectively optimizing the performance of multi-core CPUs,and significantly improve the performance of airborne graphics applications while improving product concentration.
