PCI总线设备的开发过程及应用实例

PCI总线是一种标准的计算机总线,它具有即插即用、低功耗、数据传输率高等特点。PCI总线已经逐渐取代ISA和EISA总线的位置。PCI总线涉及的规范比较多,接口说明复杂,开发出高效、稳定的PCI总线设备具有一定难度。基于具体实践总结了PCI总线设备的开发过程,并结合PLX公司的9054接口芯片给出了一个应用实例。

Development and Application of PCI bus

PCI bus is a type of standard computer bus with characteristics of the plug and play (PnP), low power and high data - transmitting rate. PCI bus is taking the place of ISA and EISA buses gradually. Many specifications are involved with PCI bus and interface explanation is complicated, so it' s difficult to develop the stable PCI bus equipment of high performance. This article summarizes the development course of PCI bus based on the practice and gives an application example based on 9054 interface chip of PLX Corporation.
