Abstract
PURPOSE: To increase the process efficiency of the CPU for the data transfer queuing control system for an electronic exchange unit, by setting the queuing time in accordance with the transmission delay time between the CPU and each terminal unit and thus decreasing the ineffective time.
CONSTITUTION: The returning bus 16 is provided between the CPU2 and each of the terminal units 31W3n. In other words, the address transmitted to the address bus 6 when the in-instruction is transmitted is collated at each of the terminal units 31W3n. The terminal unit having a coincidence of collation knows that it has been selected, and then transmits the coincidence signal to the bus 16 via the bus driver e.g. 151. When the signal 16 is detected at the CPU2, the queuing signal is cancelled. Accordingly, the queuing time can be made different with every terminal unit. As a result, the ineffective time can be reduced to increase the process efficiency of the CPU.
