Implementations
The 167-processor AsAP 2 chip enables individual processors to make extremely fast (on the order of 1-2ns) and locally-controlled changes to their own supply voltages. Processors connect their local power grid to either a higher (VddHi) or lower (VddLow) supply voltage, or can be cut off entirely from either grid to dramatically cut leakage power.
