Title: METHOD AND TERMINAL FOR DETERMINING TERMINAL PROCESSOR VOLTAGE
Abstract:
A method (100) and terminal (300) for determining terminal processor voltage. The terminal (300) comprises a CPU (310) and an auxiliary processor (320), and the method (100) comprises: during a booting process of the terminal (300), determining a minimum operating voltage of the CPU (310) after the auxiliary processor (320) completes system initialization (S110); configuring, by the auxiliary processor (320), a current voltage of the CPU (310) as the minimum operating voltage (S120); completing, by the CPU (310), the booting process of the terminal (300) under the minimum operating voltage, and then controlling, by the CPU (310), the terminal (300) to operate (S130). The method (100) and terminal (300) for determining terminal processor voltage can determine the minimum operating voltage of the CPU (310) during the booting process of the terminal (300), and can reduce the test time and test costs, increase the test precision and test the minimum operating voltage of a processor more accurately in comparison with using an automatic test equipment to measure the minimum operating voltage of the processor during the production of the processor.
