GeodeLink™ Architecture
GeodeLink™ architecture connects the internal modules of the AMD Geode™ GX processor using the data channels pro-
vided by GeodeLink Interface Units (GLIUs). GeodeLink modules are connected to GLIU ports 1 – 7 as shown in Figure 3-
1. Port 0 is always the GLIU itself. GLIUs can be chained together and up to a maximum of six GLIUs can be connected
allowing for 32 modules.
