PROBLEM TO BE SOLVED: To allow a completion notification signal to be transmitted and received while suppressing an occurrence of wasteful waiting time in a plurality of processors.SOLUTION: A communication system comprises: a plurality of processors synchronously operating and transmitting completion notification signals being active by clock numbers different from another; an OR circuit receiving the completion notification signal from at least one out of the plurality of processors, OR-computing, and outputting a completion notification OR signal; and a communication medium causing the processors to receive the completion notification OR signal. Each processor includes an OR signal receiving section and a completion notification transmission section. When the completion notification OR signal is active at a next clock period after transmission of the completion notification signal is completed, the completion notification transmission section repeatedly executes waiting and the transmission of the completion notification signal after the waiting until the completion notification OR signal becomes inactive at the next clock period, and, when the completion notification OR signal is inactive at the next clock period, completes the transmission of the completion notification signal after the waiting.SELECTED DRAWING: Figure 2 【課題】複数の処理装置における無駄な待機時間の発生を抑制しつつ完了通知信号を送受信可能とする。【解決手段】通信システムは、同期動作して互いに異なるクロック数だけアクティブな完了通知信号を送信する複数の処理装置と、処理装置のうち少なくとも１つから完了通知信号を受信しＯＲ演算して完了通知ＯＲ信号を出力するＯＲ回路と、完了通知ＯＲ信号を処理装置に受信させる通信媒体とを備え、処理装置は、ＯＲ信号受信部と完了通知送信部とを有し、完了通知送信部は、完了通知信号の送信が完了した次のクロック周期に完了通知ＯＲ信号がアクティブである場合、次のクロック周期に完了通知ＯＲ信号が非アクティブとなるまで、待機と、待機後の完了通知信号の送信と、を繰り返し実行し、次のクロック周期に完了通知ＯＲ信号が非アクティブである場合、待機後の完了通知信号の送信を終了する。【選択図】図２
