ABSTRACT:
A read-out signal generator supplies read-out signals through a read-out bus bar to sources of first data signals and buffer memories storing second data signals produced by accompanying central processing units (CPU's) to make the read-out bus bar transmit also the first and second data signals in timed relation to the read-out signals. A coupling device supplies read-in signals with reference to the read-out signals and transfers the first and second data signals from the read-out bus bar to a read-in bus bar, which supplies the transferred data signals to the CPU's in predetermined time relation to the read-in signals. The coupling device may either be a mere connection (in which case the read-out signals serve as the read-in signals) or a data bank.
