在嵌入式實時系統中進行軟硬件開發的關鍵是編寫高效可靠的設備驅動程序，而VxWorks下END網口驅動程序是設備驅動程序中較為復雜的一類。首先從整體上分析了VxWorks操作系統的特點與結構，然后介紹了VxWorks中設備驅動程序的功能、結構和開發方法，并給出了END網口驅動程序的設計實例。該文對VxWorks設備驅動程序開發者具有參考價值，通過本文可以方便的進行END驅動的配置和使用。

　　Abstract:

　　In embedded real-time hardware and software systems development, the key is the preparation of highly efficient and reliable device drivers, and VxWorks enhanced network driver (END) is relatively a complicated one among all device drivers. This paper first analyzed the features and structures of VxWorks operating system, and then introduced the functions, structures and development methods of the VxWorks device driver, whats more,it gives the design of an END driver as an illustration. This paper has practical value to VxWorks device driver developers, and it can be easily carried out by END-driven configuration and use.
