COMPUTER SYSTEM AND METHOD FOR ADJUSTMENT OF FREQUENCY OF CPU CLOCK SIGNAL AT INSIDE OF COMPUTER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a computer system provided with a heuristic clock speed optimization mechanism for making the computer system capable of performing an operation at an optimum clock frequency without being overheated. SOLUTION: A microprocessor 102 is provided with a programmable heat sensor 130 incorporated on a relating semiconductor die for generating signals for indicating the temperature of the semiconductor die. Control signals are supplied to a frequency synthesizer 110 for controlling the frequency of CPU clock signals. The frequency synthesizer 110 is dynamically controlled so as to change the frequency of the CPU clock signals so as to make the microprocessor 102 perform the operation at the optimum frequency while preventing overheating.
