Abstract:
1. A computer system capable of modulating a voltage and a frequency of a central processing unit, comprising: a central processing unit capable of receiving a voltage and then generating a feedback voltage; a pulse-width-modulation controller capable of modulating and outputting the voltage in response to a compensated-feedback voltage, and capable of monitoring a real-time load of the central processing unit and then generating a power monitor signal; an embedded controller for determining a power consumption of the central processing unit in response to the power monitor signal and then generating a control signal and a system interrupt notify signal; a voltage modulation unit capable of generating a compensate voltage in response to the control signal; a clock-frequency generator for generating a clock with a first frequency to the central processing unit; and a basic-input-output-system for modulating the first frequency of the clock based on the system interrupt notify signal; wherein the compensated-feedback voltage is equal to the feedback voltage added to the compensate voltage and wherein the compensate voltage is non-zero.
