Abstract
PURPOSE: To perform the interrupt processing efficiently by using a common bus to report its own processor number and the interruptible state when each processor of plural processors becomes an interruptible state.
CONSTITUTION: Master access circuit 1 issues use request 101 to common bus 10 when processor P1 becomes an interruptible state. When use approval 102 is returned from bus 10, enable signal 103 is transferred to interrupt enable indication means 2 and address indication means 3. Indication means 2 sends a signal to bus 10 through interrupt enable signal line 104 when signal 103 comes. Indication means 3 outputs address information corresponding to processor P1 to address line 105 of use bus 10 when signal 103 comes.
