Abstract
Methods and apparatuses provide voltage regulation for a processor. Control or configuration parameters for a voltage regulator (VR) are provided digitally over a configuration bus to a VR controller. The parameters may be provided directly from a storage element, or via a processing element or processor core. Based in whole or in part on the parameters, the VR controller provides an output control signal to affect a power output from a power converter to the processing element. In one embodiment, the VR controller is integrated onto the same IC as the processing element.
