1.7.1 Reference Designs
As described previously, the GX1 series of integrated pro-
cessors is designed specifically to work with National’s
Geode I/O and graphics companion devices. To help define
and drive the emerging information appliance market, sev-
eral reference systems have been developed by National
Semiconductor. These GX1 processor based reference
systems provide optimized and targeted solutions for three
main segments of the information appliance market: Per-
sonal Internet Access, Thin Client, and Set-top Box. Con-
tact your local National Semiconductor sales or field
