基于VxWorks6.7的显示驱动设计与实现

Research of Display Driver Base on VxWorks6.7

为了在VxWorks6.7操作系统下实现一款显示芯片SIS315的图形显示功能,提出了一种基于SIS315图形处理器的显示驱动软件的设计方法;该方法采用风河公司提供的WindML5.2驱动程序框架,设计了SIS315图形芯片的显示驱动软件,并对SIS315图形处理器进行相应的优化,实现2D硬件加速功能,显著提高了图形显示的实时性;应用结果表明,该方法运行稳定,图形显示实时性高,充分发挥了SIS315图形处理器功能。

In order to realize the display driver of SIS315in the VxWorks6.7operate system,we have gave a method of design on display driver Based on SIS315.The method uses the wind river company provides the WindML5.2driver framework,designs the display drivers with SIS315graphics processor,and the optimization of SIS315graphics processor with hardware acceleration function,significantly improves the real-time graphical display.The application shows tha this method is stable,the highly real-time on display,give full play to the function of SIS315graphics processor.
