Abstract
An exemplary CPU frequency regulating circuit includes a detecting circuit, and a comparing circuit. The detecting circuit receives a PWM signal from a super I/O chipset, and converts the PWM signal to a load voltage responsive to a workload of a CPU. The comparing circuit is coupled to the detecting circuit for receiving the load voltage, and compares the load voltage with a reference voltage, and adjusts a frequency of the CPU according to a result of the comparison.
