Abstract: A system for delivering power to a device in a specified voltage range is disclosed. The system includes a power delivery network, characterized by a response function, to deliver power to the device. A current computation unit stores values representing a sequence of current amplitudes drawn by the device on successive clock cycles, and provides them to a current to voltage computation unit. The current to voltage computation unit filters the current amplitudes according to coefficients derived from the response function to provide an estimate of the voltage seen by the device. Operation of the device is adjusted if the estimated voltage falls outside the specified range.

Abstract: A processor includes a digital throttle to monitor the activity of various units of the processor's instruction execution pipeline, and to determine a power state for the processor from the monitored activity. One of two or more power control mechanisms is engaged, responsive to the power state of the processor reaching a threshold.

Abstract: An architecture for registers and/or memory may provide a selectively disable payload portion. The architecture induced energy conservation. The architecture may include two or more payload portions for storage of payload data and a portion for storage of administrative data. Based on the contacts of the administrative data, certain payload portions may be enabled or disabled.
