Abstract
A TMR unit connects a plurality of processors by a bus and simultaneously executes the same processing operation. Among the plurality of processors, one of them is a master and the remaining processors are slaves. Information formed by only the master processor is outputted to the bus. Each processor has a multiplex control circuit. The multiplex control circuit compares output information formed by itself with bus information outputted to the bus, thereby detecting a failure and allowing an internal circuit to execute necessary processes.
