Abstract
An approach for power reduction of an integrated circuit device. In response to detecting a change in an activity factor associated with an integrated circuit device from a first activity factor to a second activity factor, a supply voltage and a body bias associated with the integrated circuit device are adjusted based on the second activity factor to reduce power consumption. For one aspect, the supply voltage and body bias are adjusted to maintain a substantially constant operating frequency for the integrated circuit device.
