Abstract

PURPOSE:To eliminate a waste of time due to delay by varying the delay of a signal on the operation start indication control line of a digital transmission line at its rise and fall. CONSTITUTION:Between input and output controllers 1 and 2, lines 101-10n for data transmission, input-output indication control line 201, operation start indication control line 203, and operation response control line 202 are provided. An input- output indication signal and operation start indication signal are outputted nearly at the same time and while the output of the operation response indication signal stops the output of the operation start indication signal, the stop of the output of the operation response indication signal stops the input-output indication signal. Delay circuit 230 that provides 2T delay at the rise of the above-mentioned operation start indication signal and nearly eliminates the delay at the fall of the indication is used to eliminate a waste of time 2T.
