The GeodeLink architecture is designed for information appliance systems ranging from thin clients, set-top boxes, and personal Internet access devices to home networking and residential gateways. It provides a system infrastructure that begins with a signal interface and layers diagnostics, power management, software, design verification, and floor planning. It features unified memory architecture (UMA), distributed switched fabric interconnect, and active hardware power management. UMA enables up to 2GBps memory bandwidth while using only one memory interface. The memory controller supports 32 and 64 bits at 133MHz SDRAM and 266MHz DDR-SDRAM. In addition, the architecture provides a standard software model by means of a virtual PCI system, which allows legacy PCI drivers to work on integrated intellectual property. The GeodeLink architecture samples in the third quarter of 2001. Production is scheduled for early 2002.
