摘　　要：基于提高图形显示效率,缩短ARM2440平台图形加载时间的目的,设计并实现了基于ARM2440平台的图形驱动程序。该驱动程序没有以操作系统作为支撑,而是采用直接驱动硬件的方法,通过实现ARM2440平台上各种硬件设备的驱动,例如UART串口驱动、NandFlash驱动、以及LCD触摸屏驱动等,最终达到显示图形的目的。该驱动程序具有加载速度快,显示效率高的特点。适用于需要快速显示图形的设备。Based on the purpose of improving the graphic display efficiency and shorten graphics load time on ARM2440 platform, a graphic driver based on ARM2440 is devised. The drive is implemented directly on the hardware ,not supported by the operating system. By completing various hardware devices drives on ARM2440 platform, such as UART serial port driver, NandFlash drive, LCD touch screen driver, and ultimately achieve the purpose of display graphics. The graphic driver has the features, such as load quickly and efficiency. The driver for devices that need display graphics quickly.
