Abstract :
A computer architecture, FTP-AP, has been designed that can efficiently implement N-version fault-tolerant software and still tolerate random hardware failures with extremely high coverage. A unified architectural approach extends a well-known hardware fault tolerant without violating the fundamental hardware fault-tolerance design principles, and it provides a possible solution to the problem of correlated software errors.<>
