Abstract
PURPOSE: To ensure the timing control without the timing control circuit.
CONSTITUTION: In the information processing system in which each unit is connected commonly with the bus line, the circuit consists of the first FF61 set at the interruption raquest, second FF66 set during the usage of bus by the unit, first gate 63 inhibiting the output of FF61 with the signal representing that the unit itself uses the bus, delay circuit 64 compensating the output of the gate 63 by the time until the interruption enable signal from the unit having the lowest priority among each unit connected to the bus is off, and second gate 65 inputting the output of the delay circuit, interruption enable signal from other units, and further the signal representing the usage condition of the bus and controlling the second FF66.
