Abstract: A portable device is provided. A first processor performs an initial procedure according to an operation clock with a first frequency value and an operation voltage with a first voltage value, and performs a calibration procedure according to the operation clock with a second frequency value and the operation voltage with a second voltage value when the initial procedure has been performed and a self-calibration event is present. A second processor detects whether a specific function of the calibration procedure is being performed by the first processor. The second processor stores the second frequency value and the second voltage value into a storage unit after the calibration procedure is performed. The second voltage value is lower than the first voltage value, and the second frequency value is lower than the first frequency value.
