ABSTRACT:
A program controlled data processing system which includes two data manipulation units generally operated in parallel. The two data manipulation units, however, by design react differently in the execution of certain program order words. The system includes a circuit arrangement which compares data generated by the two data manipulation units and generates comparison signals indicating the identity or lack of identity of the compared data. The comparison signals are utilized in the detection of faults and errors and in the determination of conditions as defined by the program.
