Architecture Overview
As illustrated in Figure 1-1 on page 13, the SC1200/
SC1201 processor contains the following modules in one
integrated device:
• GX1 Module:
• Video Processor Module:
• Core Logic Module:
• SuperI/O Module:
2.1
The GX1 processor (silicon revision 8.1.1) is the central
module of the SC1200/SC1201 processor. For detailed
information regarding the GX1 module, refer to the AMD
Geode™ GX1 Processor Data Book and the AMD
Geode™ GX1 Processor Silicon Revision 8.1.1 Specifica-
tion Update documents.

GX1 Module
2.0Architecture Overview
The SC1200/SC1201 processor’s device ID is contained in
the GX1 module. Software can detect the revision by read-
ing the DIR0 and DIR1 Configuration registers (see Config-
uration registers in the AMD Geode™ GX1 Processor Data
Book). The AMD Geode™ SC1200/SC1201 Processor
Specification Update document contains the specific val-
ues.
2.1.1
The GX1 module is connected to external SDRAM devices.
For more information see Section 3.4.2 "Memory Interface
Signals" on page 50, and the “Memory Controller” chapter
in the AMD Geode™ GX1 Processor Data Book.
There are some differences in the SC1200/SC1201 pro-
cessor’s memory controller and the stand-alone GX1 pro-
cessor’s memory controller:
1)
2)
Table 2-1 on page 18 summarizes the 32-bit registers con-
tained in the SC1200/SC1201 processor’s memory control-
ler. Table 2-2 on page 18 gives detailed register/bit formats.
There is drive strength/slew control in the SC1200/
SC1201 that is not in the GX1. The bits that control
this function are in the MC_MEM_CNTRL1 and
MC_MEM_CNTRL2 registers. In the GX1 processor,
these bits are marked as reserved.
The SC1200/SC1201 supports two banks of memory.
The GX1 supports four banks of memory. In addition,
the SC1200/SC1201 supports a maximum of eight
devices and the GX1 supports up to 32 devices. With
this difference, the MC_BANK_CFG register is differ-
ent.
