Zusammenfassung:In controlling power in a portable computing device ("PCD"), a power supply input to a PCD subsystem may be modulated with a modulation signal when an over-current condition is detected. Detection of the modulation signal may indicate to a processing core of the subsystem to reduce its processing load. Compensation for the modulation signal in the power supply input may be applied so that the processing core is essentially unaffected by the modulation signal.
