2.5.1 GeodeLink™ PCI Bridge Overview
The GeodeLink™ PCI Bridge (GLPCI) module provides a PCI interface for GeodeLink
Interface Unit-based designs. The GLPCI module is composed of six major blocks:
GeodeLink Interface
FIFO/Synchronization
Transaction Forwarding
PCI Bus Interface
PCI Arbiter
The GeodeLink™ and PCI Bus Interface blocks provide adaptation to the respective
buses. The Transaction Forwarding block provides bridging logic. Some of the features of
the GeodeLink™ PCI Bridge are listed below:
PCI Version 2.2 compliance
32-bit, 66 MHz PCI bus operation
Target support for fast back-to-back transactions
Arbiter support for three external PCI bus masters
Write gathering and write posting for in-bound write requests
Virtual PCI header support
Delayed transactions for in-bound read requests
Zero wait state operation within a PCI burst
Dynamic clock stop/start support for GLIU and PCI clock domains (this is not
CLKRUN support)
Capable of handling out of bound transactions immediately after reset
2.5.2 10/100M Ethernet
Two highly integrated and cost-effective single-chip, Realtek RTL8100C 10/100 Mb/s fast
Ethernet controllers are interfaced through first the PCI bus and then through the
