Abstract
PURPOSE: To simplify the interruption display circuit of double buffer type of the central processing unit, by providing the circuit enabling to deliver the interruption signal by sufficiently longer timing than the instruction execution time of the central processing unit at the data channel unit.
CONSTITUTION: The input terminal 6 of the interruption display FF(ISF)2 having the set gate 4 is connected to the delivery end 102 of the interruption signal delivery circuit of the data channel unit (DCH), and other input terminal is connected to the write-in gate 3 from the internal bus of the central processing unit (CC). When DCH sets the interruption request FF(IRQF) 101 to 1 with the output of the decoder 105, the interruption request signal is outputted by one machine cycle, and when the IRQF 101 is continuously operated by n times, the interruption request signal is outputted in the timing of n-th signal of the machine cycle. When the interruption request signal is outputted longer than the execution time T1 of instruction, after ISF 2 is 1, since signal 1 is given to the terminal 6, even if signal 0 is given to the gate 4 of CC with the gate 3, ISF 2 keeps the state of 1.
