A plurality of CPU units are used for multiple CPU control. Each CPU unit includes a device memory for processing device data, a shared memory for reading data from and writing data into the CPU unit and other CPU units, and OS describing the procedure for transferring data, and a microprocessor for transferring data between its own CPU unit and other CPU units according to the procedure described in the OS. Each microprocessor fetches the device data stored in the shared memory of other CPU units into the device memory of its own CPU unit.
