Claim 5:
6. An electronic device, comprising:
a processor, configured to send power supply scaling information to a power supply based on an operating frequency in a next time period, wherein the power supply scaling information comprises a specified supply voltage V of the operating frequency in the next time period, which is defined as a specified supply voltage determined by the processor based on the operating frequency in the next time period, and the operating frequency in the next time period is an operating frequency predicted based on a current operating frequency in a current time period; and
the power supply, configured to provide a supply voltage Vout to the processor based on the specified supply voltage V of the operating frequency in the next time period and a specified voltage slope R of the operating frequency in the next time period, wherein
the voltage slope is a decrease speed of the supply voltage Vout as a load current of the power supply increases; the supply voltage Vout decreases as the load current increases; and Vmin≤Vout≤V, wherein Vmin is a lowest supply voltage for operation of the processor as the load current increases when the processor operates at the operating frequency in the next time period.
