Abstract: The processor comprises multiple sub-systems. Each sub-system is configured to generate a voltage switching signal. The processor also comprises a packetizing module coupled to the sub-systems. The packetizing module packetizes multiple voltage switching signals generated by the sub-systems to a packet. The processor also comprises a PMIF (power management interface) configured to receive the packet and output the packet.

Abstract: A voltage control method for a switched mode power supply (SMPS) is provided. A first voltage value is determined, and a voltage adjustment mode of the SMPS is enabled. In the voltage adjustment mode, user modules operate in an operation scenario, and whether one of the user modules enables a high-voltage requirement is determined according to operation states of at least two user modules. In response to one user module enabling the high-voltage requirement, the switched mode power supply is controlled to generate a power supply voltage with the first voltage value. LDOs generate output voltages according to the power supply voltage for driving the user modules respectively. In response to none of the plurality of user modules enabling the high-voltage requirement, the SMPS is controlled to generate the power supply voltage with a voltage value that is less than the first voltage value.
