Abstract
Power-gating circuit resources of an integrated circuit is described. The circuit resources are associated into sets responsive to utilization levels. The associating includes providing a first set of the sets, a first number of the circuit resources in the first set being associated with a first level of utilization. The associating also includes providing a second set of the sets, a second number of the circuit resources in the second set being associated with a second level of utilization. The first number is less than the second number responsive to the first level of utilization being greater than the second level of utilization. The circuit resources of the first set are commonly coupled to a reference voltage level via a first gating circuit. The circuit resources of the second set are commonly gated to the same or a different reference voltage level via a second gating circuit.
