Claim 9:
10. The device according to claim 9, wherein the processor is further configured to:
search, based on the performance difference information, a correspondence between performance differences and lowest supply voltage differences that are of a plurality of processors for a lowest supply voltage difference that matches the performance difference information; and
calibrate a specified supply voltage of each operating frequency in the target correspondence based on the lowest supply voltage difference that matches the performance difference information causing the calibrated target correspondence to match the processor comprised in the electronic device; or, the processor is further configured to:
search, based on a current temperature, a correspondence between performance differences and lowest supply voltage differences that are of a plurality of processors within a plurality of temperature intervals for a correspondence between the performance differences and lowest supply voltage differences that are of the plurality of processors within a temperature interval of the current temperature;
search, based on the performance difference information, the correspondence between performance differences and lowest supply voltage differences that are of the plurality of processors within the temperature interval of the current temperature for a lowest supply voltage difference that matches the performance difference information; and
calibrate a specified supply voltage of each operating frequency in the target correspondence based on the lowest supply voltage difference that matches the performance difference information causing the calibrated target correspondence to match the processor comprised in the electronic device.
