Abstract
A method, apparatus or stored program for adjusting the clock throttle rate of a central processing unit (CPU) included in a computer, in which the usage of the CPU is measured, so that the clock throttle rate of the CPU can be automatically adjusted on the measured usage of the CPU, thereby reducing the consumption of electric power without any influence on the performance of the computer.
Claims18
A method for adjusting a clock throttle rate of a central processing unit (CPU), comprising:
- measuring a usage of the CPU;
- comparing the measured CPU usage with a predetermined reference CPU usage range;
- and
- adjusting the clock throttle rate of the CPU.
A computer, comprising:
- user interface means for enabling clock throttle rate adjustment based on CPU usage;
- power management means for controlling a CPU's clock throttle rate;
- and
- device driver means for reading CPU usage and controlling said power management means.
A stored program for machine implemented adjustment of a clock throttle rate of a central processing unit (CPU), comprising:
- a first routine that measures a usage of the CPU;
- a second routine for comparing the measured CPU usage with a predetermined CPU usage range;
- and
- a third routine for adjusting the clock throttle rate of the CPU.
