摘要
为满足工业中仪表盘的应用和显示要求,提出基于多核Cortex-A9硬件加速的三维汽车仪表系统设计方案。为了提升三维仪表的视觉效果,采用基于Open GLES2.0的GPU硬件加速技术来提高仪表图形的渲染帧率。同时,对Linux内核做了优化,保证了图形运行时的流畅性。实验结果表明,该设计方案不仅能实时处理系统模块的信息,大幅降低CPU的使用率,且使三维汽车仪表更具真实感,达到了实际的测试要求。
A design scheme of 3D automotive instrument system based on multi-core Cortex-A9 hardware acceleration is proposed to satisfy the application and display requirements of dashboard. In order to enhance the visual effect of 3D instrument,the GPU hardware acceleration technology based on Open GLES2.0 is adopted to improve the rendering frame rate of instrument graphics. The Linux kernel is optimized to guarantee the fluency while graphics operating. The experimental results show that the scheme can not only process the information of system modules in real time,but also reduce the CPU usage greatly,and makes the 3D automotive instrument more realistic. The instrument satisfies the requirement of actual test.
