The multiprocessor system enables rapid comparison of results determined from input data at the individual microprocessors. During a first phase of the comparison the results which are to be compared are transferred from the individual microprocessors to counters in connection logic components each of which is associated with an individual microprocessor. During a second comparison phase which is started by activating a comparison line to which all the connection logic components are connected via a bus driver, the counters are simultaneously started to count for periods of time each of which corresponds to the result which has been transferred to the respective counter. The comparison line is deactivated by the counter with which the longest counting period is associated. For the purpose of determining the deactivated state, the comparison line is connected to respective inputs of the connection logic components. An interrupt request is produced at that one of the microprocessors which is associated with the counter having the longest counting period. The multiprocessor system can be used, for example, to control the optimum operation of an elevator system.
