Introduction

About the Virtex-4 ML455 PCI/PCI-X Development Kit

This kit provides a development platform for designing and verifying Virtex™-4 FPGA
based PCI and PCI-X applications utilizing Xilinx PCI LogiCORE™ intellectual property
(IP) cores in a 3.3V signaling environment. The ML455 is intended to plug-in to a 3.3V
keyed system board. The ML455 board is not a Universal add-in card nor is it intended to
plug into a 5V keyed system board.
slot (left side) from a non-supported 5V-system board slot (right side).
The ML455 board is supported by Xilinx PCI and PCI-X LogiCORE versions 3.0 and 5.0,
respectively.
