PURPOSE:To judge the interruption from which system it is originated, without setting the channel control word, by obtaining the data indentifying the computer of original interruption request from the priority control circuit. CONSTITUTION:An interruption request detection circuit 31 detects the interruption request from the computer of other system on each system, and the result is stored in an interruption register 32. By setting either one of interruption registers 321- 32n, according to the priority predetermined, the register with the highest priority is selected with the priority control circuit 33. Further, the number of register being the output of the control circuit 33 is encoded, the computer of interruption request original is identified, and the start signal is output. 34 is the register storing the encoded data and 35 is the interruption interface circuit. |
