PCI總線的應(yīng)用資料

　　The PCI Local Bus is a high performance， 32-bit or 64-bit bus with multiplexed address

　　and data lines. The bus is intended for use as an interconnect mechanism between highly

　　integrated peripheral controller components， peripheral add-in boards， and

　　processor/memory systems.

　　The PCI Local Bus Specification， Rev. 2.1 includes the protocol， electrical， mechanical，

　　and configuration specification for PCI Local Bus components and expansion boards.

　　The electrical definition provides for 5.0V and 3.3V signaling environments.

　　The PCI Local Bus Specification defines the PCI hardware environment. Contact the

　　PCI SIG for more information on the available PCI design guides and the PCI BIOS

　　Specification. For information on how to join the PCI SIG or to obtain these documents，
