1. An integrated circuit comprising:

  • a plurality of pipeline stage circuits;

    a plurality of voltage regulators integrated into the integrated circuit with the plurality of pipeline circuits, each of the plurality of voltage regulators;

    coupled to a respective pipeline stage circuit;

    configured to supply a regulated supply voltage to the respective pipeline stage circuit; and

    includes one or more energy storage components; and

    a plurality of control circuits coupled to the plurality of pipeline stage circuits and the plurality of voltage regulators, wherein;

    a given control circuit of the plurality of control circuits is coupled to an activity indicator for a given pipeline stage circuit of the plurality of pipeline circuits;

    the given control circuit is configured to cause a given voltage regulator of the plurality of voltage regulators to supply power to the given pipeline stage circuit in response to the activity indicator indicating activity;

    the given control circuit is configured to cause a clock to the given pipeline stage circuit to be gated in response to the activity indicator indicating no activity;

    the given control circuit is configured to cause the clock to be ungated in response to the activity indicator indicating activity and further in response to an expiration of a delay from the power being supplied to the given power supply circuit; and

    the gated clock is not toggling and the ungated clock is toggling.
