  • Apparatus and method to implement power management of a processor
    Patent number: 9405340
    Abstract: In an embodiment, a processor includes a plurality of cores grouped into a plurality of clusters. The clusters are formed based on a corresponding operating voltage of each core at each of a plurality of frequencies. Each cluster includes a unique set of cores and at least one cluster includes at least two of the cores. The processor also includes a power control unit (PCU) including frequency/voltage control logic, responsive to a frequency change request for a first core of a first cluster, to determine an operating voltage for the first core from a first cluster voltage-frequency (V-F) table associated with the first cluster. The first cluster V-F table uniquely specifies a corresponding operating voltage at each of a plurality of frequencies of operation of the cores of the first cluster. Other embodiments are described and claimed.
