PURPOSE: To attain the mutual synchronization of the operations of separated integrated circuits by transferring clock signals through independent adjustable delay circuits to each node of several mutually connected synchronizing integrated circuits, and adjusting the time delay of each delay circuit so that the clock signals can synchronously reach each node. CONSTITUTION: Clock(CLOCK) signals generated by a master clock generator 12 are transmitted to each node 13 of plural separated integrated circuits 16. Then, the CLOCK signals are transferred through independent adjustable delay circuits 18 and a transmission line (connecting means) 19 to each node 13. Also, each delay circuit 18 is adjusted, and the CLOCK signals are delayed so that each pulse of the CLOCK signals can be almost simultaneously reach each node 13. Thus, the clock signals can simultaneously reach the various nodes of the circuits, and those pulses can simultaneously reach different nodes 13. |
