Windows CE显示驱动在DM6446上的设计实现

DM6446是一款有着丰富外设资源和强大计算能力的多媒体处理芯片，一般需要通过操作系统对其复杂资源进行有效管理。由于多数多媒体应用需要有图形界面，但现有平台操作系统Linux其内核和图形界面是分离的，需要另外移植，相比之下WINCE本身自带了较为优秀的图形界面，只需对其进行显示驱动的开发就能拥有一个优秀的图形界面。详细阐述了WINCE显示驱动原理和在DM6446上的设计与实现。系统启动后WINCE图形界面运行稳定，表明驱动程序实现良好。

Research and Design of Windows CE Display Driver Based on DM6446

As a Multi-media processing chip in possession of rich resource and powerful computing peripherals, DM6446 usually manages effectively the complex resource through an operating system. Since most multimedia applications require a graphical interface, the existing platform operating system is Linux whose kernel and graphical interface is separate, needing to transplant one.and as opposed to Linux, Windows CE itself comes with a GUI, just aquiring a GUI by the development of display driver simply. This paper describes the design and implementation of Windows CE display driver on DM6446.After the system's startup, graphical interface runs stablely, indicating that the driver is fine.
