Computer system capable of dynamically modulating operation voltage and frequency of cpu

A computer system capable of dynamically modulating an operation voltage of a central processing unit, comprising:

• a central processing unit from which a first voltage identification signal is outputted based on a real load of the central processing unit;
• a voltage identification converting/comparing controller capable of determining to operate in an bypass mode or a calculation mode in response to the received first voltage identification signal and capable of outputting a second voltage identification signal;
• and
• a pulse-width-modulation controller capable of generating the operation voltage to the central processing unit in response to the second voltage identification signal;
• wherein when the voltage identification converting/comparing controller is switched to operate in the calculation mode, the first voltage identification signal is not equal to the second voltage identification signal.

A computer system capable of dynamically modulating an operation frequency of a central processing unit, comprising:

• a central processing unit from which a first voltage identification signal is outputted based on a real load of the central processing unit;
• a voltage identification converting/comparing controller capable of determining to operate in an bypass mode or a calculation mode in response to the received first voltage identification signal and capable of outputting a control signal;
• and
• a frequency generator for generating a central-processing-unit clock with a specific frequency to the central processing unit in response to the control signal;
• wherein when the voltage identification converting/comparing controller is switched to operate in the bypass mode, the specific frequency is equal to a normal frequency;
• and when the voltage identification converting/comparing controller is switched to operate in the calculation mode, the specific frequency is modulated to either a higher or a lower than the normal operation frequency.
