RESET SUPERVISOR

摘要

Multiple processor systems are provided. A first processor is configured to monitor the state of at least one other processor by comparing received signals. When the first processor determines that another processor needs to be reset, the first processor provides a reset signal to a reset pin of the processor that needs to be reset. The first processor may reset itself after providing the reset signal.

1. A device comprising:
a first processor and a second processor each configured to receive an input signal; wherein the first processor is configured to process the input signal to generate an output signal and transmit the output signal to the second processor; wherein the second processor is configured to
(i) compare the input signal to the output signal to determine whether the input signal corresponds to the output signal, and(ii) transmit a reset signal to the first processor in response to determining that the input signal does not correspond to the output signal; and wherein the first processor is further configured to load firmware in response to receiving the reset signal.
