In a multiprocessor system comprising a plurality of processor units (11 and 12) which are loosely coupled to one another and which individually carry out processing operations in accordance with control signal sets, respectively, a common memory (15) comprises subareas (331 and 332) assigned to the processor units and loaded with the control signal sets. Each control signal set is written into each subarea from each main memory (22) included in each processor unit whenever each control signal set is renewed. When a particular one of the processor units falls into disorder and interrupts the processing operation, another of the processor units accesses the subarea assigned to the particular processor unit and loads its main memory with the control signal set of the particular processor unit. Another processor unit thus takes over the processing operation interrupted by the particular processor unit.
