METHOD FOR CONTROLLING POWER CONSUMPTION FOR COMPUTER AND SYSTEM THEREOF

摘要

PURPOSE:To reduce the power consumption of computers by controlling the clock frequency thereby operating integrated circuits of microprocessors. CONSTITUTION:The calculation speed of the computer system or the number of executing instructions per second is directly related to the frequency of the clock pulse supplied to a microprocessor 13 by means of a clock signal generation circuit 15. By varying the clock frequency of the clock signal generation circuit 15, the speed of calculation or logical operation is reduced during the low-capacity calculation or the logical capacity period so as to reduce the voltage consumption.
