I thought this was interesting, thanks to a kobold. "The Au1000 is a high performance, low power system-on-a-chip (SOC) for the Internet Edge Device market. Internet Edge Devices operate on the outer edge of the Internet network and can be segmented into three groups: Enterprise, Wireless, and Residential. The wireless device market includes PDAs, palm-sized PCs, third-generation mobile phones and other wireless communications systems. Enterprise devices include VoIP telephony devices, firewalls, network printers, routers, and switches. Residential devices include such products as set-top boxes, gateways, firewalls and network appliances."

Alchemy Semiconductor's Au1000 is a complete SOC based on the MIPS32™ instruction set. Designed for maximum performance at very low power, the Au1000 runs up to 500 MHz. Power dissipation is less than a half watt for the 400 MHz version. Highly integrated with on-chip memory controllers and Internet access peripherals, the Au1000 runs a variety of operating systems, including Windows® CE, Linux® and VxWorks®. Moreover, the integration of peripherals with Alchemy Semiconductor's unique, very high performance, MIPS-compatible core provides lower system cost, smaller form factor, lower system power requirement, simpler designs at multiple performance points and thus, shorter design cycles.
