<p>PURPOSE:To freely change the execution mode of each microprocessor to improve the operational effectiveness of the titled system by setting easily the master/slave division and the operation mode of the microprocessor by processor configuration definition information. CONSTITUTION:To a shared bus 1 of the system, plural microprocessors units 2-4 of identical configuration are connected. The parallel operation of the units 2-4 is processed by a shared storage 5 connected to the bus 1. In this storage 5, a processor configuration definition information 14 which stores the corresponding to the unit number of each unit, and whether the operation mode is a system mode or test mode is provided. Also, a processor status information 15 is stored in a dual-port RAM 9 that is connected to the CPU 6 provided to each of the microprocessors 2-4 and to the bus 1. And the information 14 in the storage 5 is set in a execution control program 16 of the local ROM part 8 of each microprocessor, to be used as the information 15. The system is thus made operate effectively.</p> |
