基于BCM7241平台的DirectFB图形引擎移植研究

摘要

本文详细描述了如何在BCM7241硬件平台上移植实现DirectFB的图形引擎硬件加速功能；并把移植之后在系统性能上得到的提升与未移植之前做比较，说明DirectFB在优化BCM7241硬件平台GUI性能上的作用。%This paper describes in detail how to implement the DirectFB transplantation on BCM7241 hardware platform of the graphics engine hardware acceleration;and gets the promotion in the performance of the system after the transplantation and com-pares with the performance before transplantation, illustrating the function of DirectFB in optimizing BCM7241 hardware platform GUI performance.
