1 Introduction
The ADM-XP (XP) is an advanced PCI Mezzanine card (PMC) supporting Xilinx Virtex-II PRO™ (V2PRO)
devices, the latest development in FPGA technology. The XP supports 2VP70, 2VP100 or 2VP125 devices
with two embedded PowerPC processors.
The XP utilises an FPGA PCI bridge developed by Alpha Data supporting 64 bit PCI at up to 66MHz. Future
enhancements will provide compatibility with PCI-X. A high speed multiplexed address and data bus connects
the bridge to the target FPGA.
Memory resources provided on-board include DDR SDRAM, DDR2 SSRAM and flash, all of which are
optimised for direct use by the FPGA using IP and toolkits provided by Xilinx.
Flexible I/O is the key to the ADM-XRC-II series of boards and the XP is compatible with a wide selection of
XRM modules that use the 180 pin Samtec interface.
