摘要
简要介绍了嵌入式图形领域中2D图形加速器的基本情况,并结合Monahans的应用平台的开发,实现了基于Bootloader上的M arvell PXA300集成2D图形加速器的驱动,通过随机生成参数,测试了该图形加速器的绘图速度,并与软件加速的渲染速度进行了比较。
This paper gives a brief introduction on fundamental status of 2D graphic accelerator in embedded graphic field.The Marvell PXA300 integrated 2D graphic accelerator driver is implemented based on Bootloader in combination with the development of Monahans embedded applications platform.The performance of the graphic accelerator is tested by doing graphic operations with random parameters,and has compared it with rendering performance accelerated by the software.
