Abstract:
A mechanism is provided for efficiently recycling a charge from a power domain that is discharging. A side of a discharging power domain normally coupled to a voltage supply is disconnected from the voltage supply. The side of the precharging power domain normally coupled to the voltage supply is currently disconnected from the voltage supply. The side of the discharging power domain normally coupled to the voltage supply is connected to a side of the precharging power domain normally coupled to the voltage supply. A side of the discharging power domain normally coupled to the ground is disconnected from ground. The side of the discharging power domain normally coupled to ground is connected to the voltage supply, thereby precharging the precharging power domain with the charge from the discharging power domain that would normally he lost due to leakage.
