What's the lifetime of a digital processor?
Before this question can be answered, we need to refine the question. A simple answer could be that the lifetime of a processor is equal to its MTTF or Mean Time To Failure. This doesn't help us a lot because the MTTF is not a unique number. Leaving out the mean calculation, just like interrupt latency the Time To Failure is not a unique number. It is a histogram and the distribution will depend on the usage pattern.
