嵌入式操作系統(tǒng)VxWorks設(shè)備驅(qū)動(dòng)程序的設(shè)計(jì)

　　在嵌入式實(shí)時(shí)系統(tǒng)中進(jìn)行軟硬件開發(fā)的關(guān)鍵是編寫高效可靠的設(shè)備驅(qū)動(dòng)程序，而VxWorks下END網(wǎng)口驅(qū)動(dòng)程序是設(shè)備驅(qū)動(dòng)程序中較為復(fù)雜的一類。首先從整體上分析了VxWorks操作系統(tǒng)的特點(diǎn)與結(jié)構(gòu)，然后介紹了VxWorks中設(shè)備驅(qū)動(dòng)程序的功能、結(jié)構(gòu)和開發(fā)方法，并給出了END網(wǎng)口驅(qū)動(dòng)程序的設(shè)計(jì)實(shí)例。該文對VxWorks設(shè)備驅(qū)動(dòng)程序開發(fā)者具有參考價(jià)值，通過本文可以方便的進(jìn)行END驅(qū)動(dòng)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.
