Multiprocessor system having multiple watchdog timers and method of operation
Abstract:
A multiprocessor system with multiple watchdog timers, the timers causing all the processors in the system to concurrently process a common interrupt signal asserted by any of the watchdog timers timing out. The processors, in response to the common interrupt signal, store data residing in their local memories into a memory common to all the processors. The stored data is then stored in a permanent storage device for later analysis. Thereafter, all of the processors are reset.
