1. A method comprising:
- (a) receiving an input signal at a first processor and at a second processor;
(b) at the first processor processing the input signal to generate an output signal;
(c) transmitting the output signal from the first processor to the second processor; and
(d) at the second processor comparing the input signal to the output signal and determining that an error exists when the input signal does not correspond to the output signal.

Abstract
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.

15. A method of monitoring and resetting a processor, the method comprising:
-
(a) receiving from a port at least one bus signal at a first processor and at a second processor; (b) at the second processor determining that an error exist when the first processor does not provide the at least one bus signal to the second processor; and (c) when an error exists in (b), transmitting a reset signal from the second processor to the first processor. - View Dependent Claims (16, 17, 18)

19. A tangible computer-readable medium that contains computer-executable instructions that when executed cause a processor to perform the steps comprising:
-
(a) receiving from a port at least one bus signal; (b) receiving from another processor at least one bus signal; (c) determining that an error condition exists when the bus signals received in (a) and in (b) do not correspond; and (d) when an error condition exists, transmitting a reset signal to said another processor. - View Dependent Claims (20)
