用Crossbar Switch实现PCI的空分连接

Interlink of PCI with Crossbar Switch

PCI总线以其优越性得到了越来越多的应用,在总线扩展方面,相对于传统的共享式总线开关式总线可以动态分配带宽,很大程度上提高了系统的性能。该文提出了一种方案,使用交叉开关进行PCI总线的空分连接,以实现PCI总线的扩展,并介绍了PCI总线和交叉开关之间接口PXP的设计。

PCI Bus has been applied in many fields due to its advantages.For Bus Expansion,switched bus can distribute bandwidth dynamically compared to shared bus,it enhances system's performance.This article proposes a method of interlinking multiple PCI Bus using Crossbar Switch to implement PCI Bus expansion,and the design of interface between PCI Bus and Crossbar Switch is introduced.
