Abstract:
A multi processor system having a first processor; and one or more second processors is provided. Each of the one or more second processors is connected to the first processor by a dedicated interrupt signal line. Upon receiving a first interrupt signal indicating a power cutoff event, the first processor sends via the dedicated interrupt signal line a second interrupt signal to at least one second processor among the one or more second processors.
