Integrated circuit power domains segregated among power supply phases

Abstract:

Power supply architectures and enhanced power control techniques are presented herein. In one example, a system includes a plurality of power supply phases and a system processor. The system processor comprises a processing unit comprising a plurality of processing cores, a plurality of power domains configured to segregate power distribution for the processing unit into sets of the plurality of processing cores, and external connections configured to couple individual ones the plurality of power domains to individual ones of the plurality of power supply phases.
