摘要
PCI总线由主桥管理整个总线,目前基于对现有的PCI总线的继承和发展衍生出PCI-X总线和PCI-E总线规范,其中PCI总线控制器已应用于多种嵌入式系统。采用PCI9056的PCI总线设计,可以实现基本的PCI总线设计要求,其寄存器初始化可以通过局部总线一侧的CPU进行,也可由存入E2PROM的内部参数自动装入。
PCI bus is managed by host/PCI bridge,PCI - X and PCI - E are derived from it. PCI system has popular application in many embedded systems. Basic functions can be met with the PCI9056. The registers initialization can be done by CPU,or it can be loaded from E2 PROM automatically.
