Method, apparatus and system for adaptively adjusting voltage
The present invention discloses a method, an apparatus, and a system for adaptively adjusting a voltage. The method includes: acquiring an internal temperature code of a system chip and a time sequence code of a system logic circuit, where the internal temperature code is detected by a temperature sensor and the time sequence code is output by a time sequence monitoring unit; selecting a time sequence reference calibration code from multiple configured time sequence reference calibration codes according to the acquired temperature code; and comparing the acquired time sequence code with the selected time sequence reference calibration code and determining, according to a comparison result, an adjustment voltage to be output for a system load. By using the foregoing method, the present invention can better reduce a power loss and achieve a better power reduction effect.
