Abstract: Systems and methods for dynamically adjusting an input parameter, such as power supply level, to a shared power domain in a portable computing device are disclosed. The power domain includes a plurality of processing resources that share the power source. The power supply level is reduced based on a critical core vote pool derived from votes from the plurality of processing resources. The critical core vote pool is narrowed from all the votes by disqualifying votes based on the operating status of the associated processing resources. For example, because inactive processing resources may be unaffected by a change in the voltage level to the shared domain, and because certain active processing resources are in a position to adjust to a power change dictated by another processing resource, such processing resources may be considered noncritical and their votes disqualified from consideration.
