摘要：

热插拔是Compact PCI总线技术中突出且最吸引用户的技术,解决了用户对系统稳定性和冗余性迫切的要求。文中分析了Compact PCI总线系统3种热插拔技术的原理,以完全热插拔技术为基础,设计热插拔系统,硬件采用热插拔电源控制器LTC1643L和PCI桥接芯片PCI9030实现硬件功能板卡,软件使用硬实时操作系统VxWorks。在分析VxWorks操作系统结构以及设备驱动程序结构后,结合PCI9030的设备配置空间的特点,编写VxWorks下Compact PCI功能板卡的驱动程序以及热插拔监控程序,最终实现系统的热插拔功能。

Abstract:

Hot swap is the most outstanding and attractive technology of Compact PCI bus,which resolves the users' requirements of stability and small redundancy.This article analyzes three hot swap principles of Compact PCI bus system,and a hot plug system based on complete hot plug is designed.As for the hardware,hot plug power supply adopts LTC1631 and the PCI bridge chip uses PCI9030.As for the software,hard real-time operating system takes VxWorks.After an analysis of the VxWorks operating system construct and device driver program,the designs of drivers and monitoring program are given to achieve the function of hot swap.

Key words: Compact PCI bus;hot swap;VxWorks;LTC1643L;PCI9030;PCI configuration space
