Foxton technology

Foxton is a system comprised of several key components: accurate power and temperature measurement; fine grained voltage control; dynamic fast-response frequency control; a microcontroller to manage the system. It can be wrapped around any processor or ASIC which can be virtually unchanged except: an asynchronous interface to the rest of the system; must support a wider range of operating voltages. The result is a self-optimizing chip dynamically delivering greatly improved performance/watt.
