Multi-microprocessor system and control method for the same
Abstract:
A multi-microprocessor system and a control method for the same are provided. The multi-microprocessor system includes a first microprocessor and a second microprocessor. The second microprocessor is coupled to the first microprocessor. The second microprocessor transmits a detecting signal to the first microprocessor and determines a state of the first microprocessor by monitoring the first microprocessor for a predetermined time period. In the event that the first microprocessor crashes, the first microprocessor is immediately rest or restarted by the second microprocessor in order to maximize stability of the multi-microprocessor system.
