IA-32系统中PCI地址空间的配置

PCI Space Configuration in IA-32 System Structure

分析了以PCI总线为基础的IA-32系统结构及其中的PCI总线分段方式,论述了PCI配置地址空间及其头标区分配情况,给出了使用汇编语言访问PCI配置地址空间的方法和源代码,以及读出数据的方法及应用。

IA-32 system structure based on PCI bus and the pattern of PCI bus are analyzed, and methods for PCI configuration address space access and source codes are introduced. Data reading from the system and its application are also discussed.
