<p>PURPOSE:To eliminate a bottle neck without giving a large revision in the inside of the circuit at a low cost between synchronization circuits with respect to the signal multiplexing and demultiplexing circuit. CONSTITUTION:The signal multiplexing and demultiplexing circuit consists of a signal multiplexing circuit 28 multiplexing signals a, b from a synchronization circuit 23, 1st-4th flip-flop circuits 29-32 and a changeover circuit 33 and a signal demultiplexing circuit 36 comprising 5th-8th flip-flop circuits 39-42 demultiplexing the multiplexed signal which are provided between synchronization circuits 23, 37 of LSIs 21, 22.</p> |
