ABSTRACT:
A multiple power supply sensor for protecting shared processor buses in a multiprocessor system. In the case that a power failure or power supply malfunction occurs in one of the processors of the system, at least one of the shared processor buses will be isolated from the malfunctioning processor. As a result, data on that bus is not corrupted by the manfunctioning processor. The isolation is accomplished by independent sensor circuits present in each processor for each bus.
