A control method and system for dynamically modulating the operation speed of a processor is disclosed. First, a current utility ratio of the processor is determined by an occurrence frequency of idle signals sent from a program executed on the processor. Next, control the processor to work at an operating clock in direct proportion to the current utility ratio. Therefore, the purposes of power conservation and temperature reduction can be achieved through appropriately lowering the operation speed when the utility ratio of the processor is lower.
