PCI总线配置及实现技术

PCI Bus Configuration and Implementation Technique

讨论了 PCI配置空间所包含的内容 ,论述了实现 PCI配置访问的优先选用的配置方法 :利用 Intel x86处理器的 I/ 0端口实现 PCI设备的配置访问的配置机制 ,详细分析了访问正在执行事务的当前 PCI总线上的目标设备的配置事务 ,并总结了 PCI配置中如何实现 IDSEL信号的关键技术 .

This paper discusses PCI bus configuration space,dissertates configuration methods implementing configuration access: using I/O ports in Intel x86 CPU to implement configuration mechanism of PCI devices configuration access, and detail analyses configuration access transaction accessing devices in PCI bus which working and summarizes key techniques how to implement IDSEL signal in configuring.
