<P>PROBLEM TO BE SOLVED: To shorten a processing time of an interruption process. <P>SOLUTION: A check CPU determines whether there is an abnormality or not in a novel PSW corresponding to the interruption process. The check CPU stores the novel PSW whose abnormality/normality has been determined, in a novel PSW storage region associated with the determination result. When the interruption process occurs, a command execution CPU acquires the determination result of the novel PSW corresponding to the interruption process from the novel PSW storage region. When the acquired determination result is normal, the command execution CPU executes the interruption process using a command address of the novel PSW associated with the determination result. <P>COPYRIGHT: (C)2012,JPO&INPIT |
