Abstract

In one embodiment, a processor includes a plurality of domains each to operate at an independently controllable voltage and frequency, a plurality of linear regulators each to receive a first voltage from an off-chip source and controllable to provide a regulated voltage to at least one of the plurality of domains, and a plurality of selectors each coupled to one of the domains, where each selector is configured to provide a regulated voltage from one of the linear regulators or a bypass voltage to a corresponding domain. Other embodiments are described and claimed.
