Abstract

PURPOSE:To execute an interruption to the processor which is executing a program of low rank, without using an exclusive interruption control unit, by comparing the rank which has combined a program rank and a subdivision rank, between the respective processors. CONSTITUTION:A register 1 for generating the rank position showing a priority rank of a program, and a division rank data generating circuit 2 for adding the division rank to the execution priority rank are provided on plural program control units, respectively. The outputs of said register 1 and circuit 2 are provided to the processor selective circuit 3 which receives a data from other processor by the communication line 101 and transmits its output to other processor through the communication line 101. Also, a program rank data from the register 1 and an interruption rank data from the communication line 104 are compared by the comparator 5, and its result is provided to the AND circuit 6. And, when the output of the signal line 102 selected by the circuit 3 is ''1'', and interruption operation start signal is output to the communication line 103 from the circuit 6, and an interruption by the processor which is executing a program of low rank is executed.
