Abstract
A windowed watchdog circuit system (100) can include a slow timer module (101) configured to receive watchdog strobe signals from a processor and to determine whether a gap time between watchdog strobe signals is longer than a slow threshold time to output a slow threshold state when the gap time is longer than the slow threshold. The windowed watchdog circuit system (100) can include a fast timer system configured to receive the watchdog strobe signals from the processor and to determine whether the gap time between watchdog strobe signals is shorter than a fast threshold time to output a fast threshold state when the gap time is shorted than the fast threshold. The windowed watchdog circuit system can be configured to output a reset state to reset the processor when any of the slow timer module and the fast timer system are outputting the slow threshold state or the fast threshold state, respectively.
