COMPACT PERIPHERAL COMPONENT INTERCONNECTION(CPCI) HOT SWAP SYSTEM

摘要

A Compact Peripheral Component Interconnection (CPCI) hot swap system is disclosed and is applied to the computer field. The system includes: a hot swap driver, which is used to monitor inserting, pulling out and running state of a device in a slot of a CPCI platform, dynamically apply for and release resources for the device, load and unload device drivers and provide a device information query and control interface to an upper application; a user unit, which is used to receive a device information query and control command input by the user, output a device information query and control request, receive and display a device information query and control result to the user; and a protection process, which is used to send the device information query and control request output by the user unit to the hot swap driver through the device information query and control interface, and send the device information query and control result returned by the hot swap driver to the user unit. The application meets CPCI hot swap specification and can support base hot swap, totally hot swap and highly reliable hot swap at the same time.
