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
