Global Concepts and Features
4.1
The information in this section provides a basic under-
standing of the architecture used to internally connect
GeodeLink™ Devices. The actual existence of architecture
is generally invisible to the user and the system program-
mer. AMD Core BIOS software provides all GeodeLink ini-
tialization and support, including related Model Specific
Registers (MSRs). Additionally, this software provides a
Virtual PCI Configuration Space that abstracts the architec-
ture to industry standard interfaces. From this interface, all
GeodeLink Devices appear in one PCI multi-function con-
figuration space header on the external PCI bus.
4.1.1
This component is based on the GeodeLink packet archi-
tecture. It consists of a set of GeodeLink Devices and a
GeodeLink Control Processor (GLCP) connected through
the GeodeLink Interface Unit (GLIU).

A simplified view of a GLIU connected with three generic
GeodeLink Devices is illustrated in Figure 4-1. The follow-
ing points are relevant:
