US 2010/0138683 A1 · POWER CONTROL UNIT WITH DIGITALLY SUPPLIED SYSTEM PARAMETERS

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.

Dependent claims

An apparatus comprising:

a voltage regulator (VR) controller responsive to configuration parameters to affect a regulated power output based at least in part on the configuration parameters;
a digital interconnect coupled to the VR controller;
and
a data source coupled to the VR controller via the digital interconnect, the data source to digitally transmit different types of configuration parameters to the VR controller over the digital interconnect.
