PURPOSE:To perform quickly information processing by using a main processor as a control processor for plural input/output devices and processors only for instruction control and maintaining status information of all processors only for instruction control in the main processor CONSTITUTION:A system processor 4 is connected to plural processors 5 only for instruction control by a bus and has a memory area where status information of each processor only for instruction control is stored. An input/output device 6 is connected to the processor 5 only for instruction control through the system processor 4. When the processor 5 only for instruction control recognizes its own state or the state of another processor, status information of another processor is obtained form the system processor 4.
