摘要： 在CPCI系统中，处理器模块可以作为系统主控模块和智能外设模块。由于传统单模式PCI-to-PCI桥只能工作在透明模式或者非透明模式，因此基于这种传统单模式PCI-to-PCI桥的CPCI处理器模块只能作为系统主控模块或智能外设模块。为了避免这种局限，该文采用通用PCI-to-PCI桥PCI6254以及PowerPC G4处理器设计了一款CPCI通用处理模块，它既可以作为系统主控模块，又可以作为智能外设模块。

Abstract: In the CPCI system, processor card can work as system control card and intelligent peripheral card. Because of the traditional single mode PCI-to-PCI bridge can only works in transparent mode or non-transparent mode, accordingly, the CPCI processor cards based on these bridges can only work as system control card or intelligent peripheral card. In order to avoid this limit, this paper designs a universal CPCI processor card using the universal mode PCI-to-PCI bridge PCI6254 and a PowerPC G4 processor, which can work as system control card and intelligent peripheral card.

Key words: universal processor card, universal mode, CPCI, P2P, PowerPC
