摘　　要：VxWorks是一种运行在目标机上的可剪裁的高性能嵌入式实时操作系统,集成了标准TCP/IP网络功能。但其支持的网卡型号有限,限制了网络资源的使用,网络驱动开发就显出其重要性。VxWorks特有的增强网络驱动(END)包含有一个多路复用层模块(MUX)将驱动程序细化,这个模块赋予了驱动独立性,使得开发者专注于驱动本身的开发,因此选择使用这种驱动模式为intel82567网卡成功实现驱动。这种特有的驱动模式在应用的过程中确实体现出其高效性,不用关心底层的转换和协议处理,对需要进行短周期END型网络驱动的开发有参考价值。VxWorks is a scalable embedded real-time operating system with great performance, which is run in the target. And the stand- ard TCP/IP protocol is integrated within the system.＇As only a few network adapters support the system, whichlimits the use of cyber source, the designing of network driver in VxWorks systems becomes vital. The MUX included in END is able to refine the driver pro- gram, which helps the designer to focus on developing the driver and gives the drive independence, so use this driving mode for successful implementation of intel82567 NIC driver. This special driving mode reflects the efficiency in the application process with no care about the underlvin~ drive conversion and orotocol processing.and may have a reference value for the short neriod desi~,nine of END.
