Abstract: A computer system capable of dynamically modulating an operation voltage and an operation frequency of a CPU comprises: a CPU from which a VID1 is outputted based on a real load of the CPU; a VID converting/comparing controller capable of determining to operate in an bypass mode or a calculation mode in response to the received VID1 signal and capable of outputting a VID2 signal and a control signal; a frequency generator for generating a CPU clock with a specific frequency to the CPU in response to the control signal; and a PWM controller capable of generating the operation voltage to the CPU in response to the VID2 signal; wherein when the VID converting/comparing controller is switched to operate in the calculation mode, the VID1 signal is not equal to the VID2 signal and the specific frequency is modulated to either a higher or a lower than a normal operation frequency by the VID converting/comparing controller.
