Abstract
PURPOSE: To ensure the timing control without the timing control circuit.
CONSTITUTION: In the information processing system in which each unit is commonly connected to the bus line, the circuit provides the first FF61 set at interrupt request, second FF66 set when the unit uses the bus, first gate 63 inhibiting the output of FF61 with the signal representing that the bus for other units including the said unit is used, delay circuit 64 compensating the output of the gate 63 for 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 64, interrupt enable signal from other units, and further the signal representing the usage condition of the bus, and controlling the second FF66.
