1. A method, comprising:

  • operating a subsystem at a current performance setting which is one of a plurality of performance settings, the subsystem having a maximum power allocation, the subsystem being capable of operating at each of the performance settings and wherein the current performance setting has a power consumption which is less than the maximum power allocation;

    determining an operational power of the subsystem at the current performance setting by using an actual power consumed by the subsystem that was previously measured at the current performance setting; and

    allocating an additional power to one or more other subsystems, wherein the additional power is determined based on a difference between the maximum power allocation for the subsystem and the operational power of the subsystem at the current performance setting.
