A single processor system features independent multiple watchdog units allocated to a processor unit of the system, the watchdog units operable to monitor for system faults and, upon detecting a fault, further operative to place the processor system into a predetermined fault reaction state. The multiple watchdog units are each provided with respective different watchdog calls which are output to the processor unit depending upon program execution.
