The GeodeLink™ PCI Bridge (GLPCI) module provides a
PCI interface for GeodeLink Interface Unit-based designs.
The GLPCI module is composed of five 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 For-
warding block provides bridging logic.

• 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 immedi-

ately after reset
