| 摘 要： | PCI总线的开发包括PCI硬件的开发以及相应驱动程序的编写。PCI总线驱动程序的实质是通过相应板卡配置空间的访问来配置系统资源。该文通过对配置空间的分析，给出了不用DDK、WINDRIVER等开发工具，而直接用I／O命令简单地访问配置空间的方法。

| Abstract: | PCI local bus is a kind of high performance bus standard. The development of PCI local bus includes hardware design and driver design. The essence of the driver is to configure the system resources through access to the configuration space of corresponding PCI card. A simple method of access to the configuration space is presented that uses the simple I/O instruction instead of the traditional development tools such as DDK,WINDRIVER after the analysis of the configuration space. |
