Abstract:
Embodiments related to controlling power distribution within a microprocessor are provided. In one example, a microprocessor comprising a power supply is provided. The example microprocessor also includes a plurality of power gate zones configured to receive power from the power supply, each power gate zone including a plurality of power gates, where the power gates within any given one of the power gate zones are controlled by the microprocessor independently of its control of power gates within any other of the power gate zones. The example microprocessor is operative to cause power initially to be supplied to a first power gate in a first one of the power gate zones, power then to be supplied to a second power gate in a second one of the power gate zones, and power then to be supplied to a third power gate in the first one of the power gate zones.
