PURPOSE:To perform the operation of a system smoothly by providing a main memory device, a system controller, a maintenance diagnostic processor, and a control processor. CONSTITUTION:The system controller 1 is provided with a main storage request control part 10 and an inter-processor communication control part 11 in its inside. The main memory request control part 10 is connected to the main memory device 2, the control processor 3, an arithmetic processor 4, and the maintenance diagnostic processor 5, and receives the requests of write and readout, etc., on the main memory device 2 from the processors 3-5, and issues a desired execution instruction, and receives reply data being returned from the main memory device 2, and sends the reply data to the processor of a request origin. The inter-processor communication control part 11 is connected to the processors 3-5, and controls communication among the processors 3-5. In such a manner, contention among the processors 3-5 can be evaded. |
