Abstract

A watchdog is a hardware circuit which is used to monitor the state of software execution of a processor. The processor is required to reset a hardware circuit, this circuit has a pre-deftned timeout period. Ifthe proc- essor does not reset the circuit before the timeout then the watchdog can either reset the processor or inform a controlling processor of the event (known as a host processor).
