PURPOSE:To assemble a composite type computer system comparatively easily, by outputting a synchronizing request signal to a synchronizing signal generating device from each computer, and synchronizing whenever one round program processing is started and finished. CONSTITUTION:When an electric power source is supplied to microcomputers 1- 3 and the processing is started, an initialize processing is executed by the computers 1-3. When this initialize processing is finished, a synchronizing request signal is outputted to a synchronizing signal generating device 4 from each computer. This signal is outputted from the computers 1-3 as 11, 21, 31, respectively. In response to said signals, the device 4 generates synchronizing interruption signals 41-43 to the computers 1-3 simultaneously when the signals 11, 21, 31 have been collected, and each computer receives the signals 41-43, executes one round program, and when the processing is finished, each computer outputs a synchronizing request signal to the device 4. In this way, the processing of plural computers is synchronized easily. |
