AMD Geode™ I/O Companion Device Interface
6.13
The Geode I/O companion device (GIO) interface provides
the system interface between the companion device and
the Geode GX processor. The GIO supports I/O compan-
ion modes for current and future I/O companion needs.
The major blocks of the GIO are:
• GIO_GLIU
• GIO_SYNC
• GIP_PCI
Features
• Provides support for the Geode CS5535 and Geode
• Has no master capabilities.

GIO_GLIU
6.13.1
The GIO_GLIU interface module is responsible for all the
GLIU slave functionality. The GIO_GLIU slave implements
a small MSR space consisting of the required standard
GLIU device MSRs and the MSR controls for the I/O com-
panion modes and the Legacy signals. The GIO_GLIU
must properly decode all possible GLIU transaction types
including the unexpected addresses, request types and
sizes, and must return the proper number of responses. In
addition, it provides error logic to detect unexpected
addresses and types and implements the processor float-
ing point exception handling logic.
6.13.2
The GIO synchronization module, GIO_SYNC, handles
synchronization of all signals that cross from the GLIU to
PCI domain or PCI to GLIU domain.
6.13.3
The GIO PCI module drives the values of the system inter-
face signals. Table 6-71 shows the source of each output
signal in each of the Geode companion device modes.
