14 Hardware Overview

3.2 LPCI-8575 PCI Expansion Card

This section describes the basic function, bus architecture and

jumper settings of the PCI expansion module LPCI-8575.

Functional Block

The LPCI-8575 expansion module is basically a PCI-to-PCI

bridge. The PCI-to-PCI bridge function in the LPCI-8575 supports

legacy address routed traffic, which provides 100% capability with

PCI drivers, application software, BIOS, O/Ss, etc. These func-

tions allow users to transfer their designs without extra effort.

The LPCI-8575 employs a serial interconnect technology,

622Mbps low voltage differential signaling (LVDS). Each LPCI-

8575 expansion module has one link port, the link port is divided

into transmit (TX) and receive (RX). Four TX and RX differential

pairs in the link are used to provide 2.5Gbps full duplex link band-

width or 5Gbps of total bandwidth. Incorporated with the high

speed serial LVDS, it is easy to extend the transmission up to 10

meters through shielded twisted pair copper cables.

Inside the PCI-to-PCI bridge, a PCI-to-StarFabric/StarFabric-to-

PCI converter is used to translate PCI transactions into StarFabric

frames and StarFabric frames into PCI transactions. The PCI inter-

face of the LPCI-8575 is capable of 32-bit/66MHz. Thus the maxi-

mum data throughput can up to 264Mbytes/s. The PCI interface in

LPCI-8575 acts like the primary side of a PCI-to-PCI bridge if

LPCI-8575 is plugged into the peripheral slot.
