SIMULTANEOUS INTERRUPTION PROCESSOR, SIMULTANEOUS INTERRUPTION PROCESSING METHOD AND SIMULTANEOUS INTERRUPTION PROCESSING PROGRAM PERFORMED BY COMPUTER

摘要

PROBLEM TO BE SOLVED: To reduce overheads at the time of an interruption processing in a computer compared to a conventional case. SOLUTION: In the case that a prescribed number of events or messages are held, an interruption controller 3 holds the contents of the prescribed number of the events or the messages generated from magnetic disk controllers 4 and 5 or a LAN controller 6 and simultaneously reports them to an arithmetic unit 2. The arithmetic unit 2 preserves a software performance environment immediately before interruption generation, performs a processing corresponding to the contents of the prescribed number of the events or the messages and restores the software performance environment immediately before the interruption generation.
