Abstract:
A system and method for providing voltage power gating. The system includes a device for providing voltage power gating. The device includes logic circuitry, a mechanism for receiving a control signal associated with the logic circuitry and a selector. The control signal indicates an active state or an idle state of the logic circuitry. The selector enables a power source to the logic circuitry in response to the control signal indicating the active state. The selector also disables the power source to the logic circuitry in response to the control signal indicating the idle state. Thus, the power source is dynamically eliminated from the logic circuitry on the device when it is in the idle state.
