摘要
热插拔是CPCI系统最重要和最具优势的特点。目前,业界尚没有一种能够同时支持基本热插拔、完全热插拔和高可靠性热插拔的实现方案。提供了一种CPCI热插拔系统,分别从系统架构、软件架构、各组成部分的数据流交互、热插拔驱动以及守护进程的工作流程5个方面阐述了整个系统的硬件和软件实现。该热插拔系统符合CPCI热插拔规范,能够同时支持基本热插拔、完全热插拔和高可靠性热插拔。
Hot swap is the most important and advanced characteristic of the CPCI system.Currently,there is still no program supporting the basic hot swap,full hot swap and high availability hot swap in the industry.A CPCI hot swap system is provided in this article and the hardware implementation and the software design of the entire system are described from five aspects,including system structure,software structure,data exchange among various components,hot swap driver and daemon processes.This CPCI hot swap system conforms to the CPCI Hot Swap Specification,which can support basic hot swap,full hot swap and high availability hot swap.
