核心路由器中VxWorks设备驱动程序的设计与实现

Design and Realization of Vx Works Device Driver in Core Routers

核心路由处理单元通常采用以奔腾Ⅲ芯片为主控CPU的功能单板,涉及到VxWorks下的设备驱动程序设计,主要用来为协议处理板提供初始化程序,并为板上芯片等硬件设备和通信口提供设备驱动程序。文章从BSP开发中涉及的关键技术出发,就VxWorks设备驱动设计与实现中的难点和重点问题给出了解决方案。

It appears many real-time systems based on Pentium Ⅲ are used as kerne! network element management unit, which are involved in the development of device driver under VxWorks operating system. BSP is used to provide initial programs for all kind of single boards and other device drivers for chips on boards and communication ports. This paper introduces several key techniques based on BSP developing. These solutions are expanded to handicaps and emphases in VxWorks operating system development.
