Abstract
A clock management circuit and a clock management method are used for managing an operating clock of a processor circuit, and the processor circuit changes the level of a state signal according to an interrupt signal. The clock management circuit includes a delay circuit for delaying a wake-up interrupt to generate a delayed wake-up interrupt; and a clock control circuit for generating the operating clock according to a reference clock, generating the wake-up interrupt according to the state signal, and adjusting the frequency of the operating clock according to the delayed wake-up interrupt.
