Abstract
Each task assigned to a core can be considered an 'active' task. Sequential strobe signals of a watchdog signal can be spaced apart in time by a certain duration. The duration between strobe signals is longer than the expected duration of an active task. By knowing that all tasks being monitored are expected to execute within an expected amount of time, the duration between the strobe signals can be set to be longer than that expected amount of time. If a task has not transitioned to inactive by a next strobe, a watchdog error has occurred.
