Abstract: Systems and methods for dynamically adjusting an input parameter to a power domain in a portable computing device are disclosed. The power domain includes two or more processing resources that share a power source. Dynamic use of the two or more processing resources creates an opportunity to adjust the input parameter when a status change associated with a processing resource in the power domain occurs. A controller in the power domain includes logic that responds to a status indicator associated with a respective processing resource in the power domain by generating a control signal that directs a device to adjust one or both of input voltage and clock frequency.
