Abstract: An interrupt processing method performing the interrupt waiting instruction for an interrupt based processor is provided to reduce overall power consumption for the interrupt latency by being operated in two kinds of action mode of general mode and low power mode. A processor determines whether command is the interrupt standby command or not in an ID(instruction decoding) step(S101). If the command accords with the interrupt standby command, a processor converts a general mode into a low power mode(S102). The processor waits in the low power mode(S104). If the command does not accord with the interrupt standby command, a processor processes the general command in a general mode(S103). A processor determines whether or not the interrupt is generated while waiting in the low power mode(S105). In the interrupt is generated, a processor converts a low power mode into a general mode(S106) and processes the general instruction processing the interrupt service routine in the general mode.
