摘　　要：在嵌入式实时系统中进行软硬件开发的关键是编写高效可靠的设备驱动程序,而VxWorks下END网口驱动程序是设备驱动程序中较为复杂的一类。首先从整体上分析了VxWorks操作系统的特点与结构,然后介绍了VxWorks中设备驱动程序的功能、结构和开发方法,并给出了END网口驱动程序的设计实例。该文对VxWorks设备驱动程序开发者具有参考价值,通过本文可以方便的进行END驱动的配置和使用。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, what＇s 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.
