Abstract
A multiple data processing system includes first and second microprocessors for executing the same data processing in parallel fashion. A selector selectively delivers one of the output data of the microprocessors to an external I/O device. A comparator detects an off normal data processing state by comparing the output data of the first microprocessor with the output data of the second microprocessor. An operation monitor evaluates the operation state of the microprocessors in response to a signal from the comparator and instructs the selector to deliver output data sent from a normal channel to the external I/O device.
