  • Publication number: 20110241725
    Abstract: When an operation of a specified one of monitor circuits is defective or any of elements forming a ring oscillator in each of the monitor circuits has characteristic abnormality, if voltage control is performed based on a result from the monitor operating at a lowest speed, a required voltage may be overestimated. This results in an increase in power consumption, and also causes an accuracy reduction when the average value of detection results from the multiple monitors is calculated. The multiple monitor circuits are provided. Of the detection results therefrom, any detection result falling outside a predetermined range is ignored, and the average value of the remaining monitor results is used as a final monitor detection value.

  • Patent number: 8004348
    Abstract: A control circuit controls a power-source-voltage feed circuit, and controls a power source voltage fed to a target circuit. A reference-speed monitor monitors whether or not a delay time of a critical path in the target circuit is satisfies a required operational speed. A voltage-difference monitor monitors a difference between the power source voltage of the target circuit and a threshold voltage of the target circuit, to output the voltage difference information. The control circuit determines whether to increase or decrease the power source voltage based on a result of monitoring by the reference-speed monitor. The control circuit determines the change rate of the power source voltage so that the control rate of the power source voltage is proportional to the voltage difference information output from the voltage-difference monitor.
