PURPOSE:To efficiently perform processing to confirm that all transmission has been completed in a multi-address communication from a transmission processor to the other processors. CONSTITUTION:A transmission means 310 stores transfer data in a data storage area 332 with the multi-address communication request of the transmission processor 100 as a turning point, and turns on a communication completion information storage area 331-1. A notice means 341 executes interruption for causing the reception processors 210 and 220 of a reception processor group 200 to request reception. When the respective reception processors 210 and 220 request reception, a transfer means 341 transfers data in a data storage area 332 to the respective reception processors 210 and 220, and turns ON communication completion information storage areas 331-2 and 3 corresponding to the processors receiving data. When the whole communication completion information storage area 331 is turned on, a communication completion notice means 360 executes interruption for communication completion notice to the transmission processor 100. |
