Abstract:
A power management method for a multi-microprocessor system is provided. The multi-microprocessor system comprises a first microprocessor and a second microprocessor. The power management method comprises steps of receiving a power down instruction; transmitting a power down notice signal to the first microprocessor from the second microprocessor, transmitting a reply signal from the first microprocessor to the second microprocessor in response to the power down notice signal, and turning off power of the first microprocessor by the second microprocessor.
