<p>PURPOSE:To imform quickly the end of data processing and to improve the processing efficiency by storing the control information to a communication memory at the side of a requester for data processing when necessary and after the processing request information. CONSTITUTION:When a processing request is outputted fom a main microprocessor M- I, a processing request information writing part 10 writes the processing request information A1 corresponding to the request contents to a communication memory CM. If the control information X is produced from a control information generating part 11 under such conditins, the part 10 writes the information X to an address next to the information A1 on the memory CM. When the processing is through with a secondary microprocessor M-II, a read control part 20 reads out the next address information. This information is decided as the control information X at a control code deciding part 22. Then a detection informing circuit 30 sends an interruption signal C to the processor M- I.</p> |
