Zusammenfassung:	Conventional fail-safe LSIs have been used for the placement of processors and comparators in chips, but have not been used for the placement of package signal pins. The adaptability of fail-safe LSIs to various peripheral circuits and high speed memory has also not been considered. An integrated internal interface, in which the output from two processors is matched, is connected to a common line internal bus, and a plurality of external interface circuits are connected to the common line internal bus. Furthermore, signal pins corresponding to two systems are disposed at opposite corners of a package, and signal pins corresponding to a common line are disposed therebetween.
