Introduction
The PLB PCI Full Bridge design provides full bridge
functionality between the Xilinx 64-bit PLB and a 32-bit
Revision 2.2 compliant Peripheral Component
Interconnect (PCI) bus. The bridge is referred to as the
PLB PCI Bridge in this document.
The Xilinx PLB is a 64-bit bus subset of the IBM PLB
described in the 64-Bit Processor Local Bus Architecture
Specification v3.5. Details on the Xilinx PLB and the PLB
IPIF are found in the Processor IP Reference Guide. This
guide is accessed via EDK help or the Xilinx website at:
http://www.xilinx.com/ise/embedded/proc_ip_ref_
guide.pdf.
The LogiCORE PCI v3.0 core provides an interface with
the PCI bus. Details of the LogiCORE PCI 32 v3.0 core
operation is found in the
Xilinx LogiCORE PCI Interface
v3.0 Product Specification and the Xilinx The Real-PCI
Design Guide v3.0.
Host bridge functionality (often called North bridge
functionality) is an optional functionality.
Configuration Read and Write PCI commands can be
performed from the PLB-side of the bridge. The PLB
PCI Bridge supports a 32-bit/33 MHz PCI bus only.
Exceptions to the support of PCI commands supported
by the v3.0 core are outlined in the
Features section.
The PLB PCI Bridge design has parameters that allow
customers to configure the bridge to suit their
application. The parameterizable features of the design
are discussed in the
Bus Interface Parameters section.
