PURPOSE:To easily and surely transfer data between plural processors by detecting unprocessed processing request information in a table to transmit this information to the other processor and detecting processing completion information, which should be reported to the other processor, in the table to transmit this information to the other processor and repeating these operations. CONSTITUTION:Processing request information in a transmission table T11, processing completion information in a reception table M11, and preceding transmitted contents are compared with one another to detect preceding transmitted processing request information or processing request information which exists in the table T11 and has not corresponding processing completion information in the table M11, and this detected information is written in a transmission buffer S11. Processing completion information existing in a transmission table T12 is written in a transmission buffer S12. Next, this processor waits for reception of information from a processor 2. Processing completion information received from the other processor and processing request information are stored in reception buffers R11 and R12 respectively. Processing completion information in the buffer R11 is written in the table M11. Processing request information in the buffer R12 is written in a table M12. These operations are repeatedly executed.
