摘　　要：针对飞腾CPU平台上OpenGL文字绘制性能较低的问题,提出一种高效文字绘制方法。基于对基础绘制流程的分析,设计文字的全属性缓存策略,减少绘制数据传输和OpenGL状态切换;并行化CPU端计算密集的过程,提升文字属性处理效率;构建实例化渲染模式,实现GPU端批量化渲染。测试结果表明,在飞腾终端平台上,该文字绘制方法的绘制性能明显优于现有工作,绘制的帧率可大幅提升,资源的利用率更加合理。Aiming at the problem of low performance when drawing OpenGL text on Phytium CPU platform,an efficient text rendering method was proposed.Based on the analysis of the basic rendering process,a full attribute caching strategy for text drawing was designed to reduce the data transmission and OpenGL state switching.The compute-intensive parts of text attribute processing on the CPU side were parallelized for more efficiency.An instanced rendering mode was built to realize batch rende-ring on GPU.Test results show that the drawing performances of the proposed method are significantly better than that of the existing work on the Phytium CPU terminal platforms.The rendering frame rate can be greatly improved,and the utilization rates of CPU and GPU resources are also more rational.
