Fault detecting apparatus for a microprocessor system |
摘要 |
A fault detecting apparatus includes first and second processors having an internal state generating logic unit for exclusive-ORing the operation outputs and generating an internal state signal of the first and second processors, and a state comparator unit included in the first and second processors for comparing the internal state signals of the first and second processors. When the internal state signals fail to coincide with each other, the state comparator unit decides on an error of at least one of the first and second processors.
