<P>PROBLEM TO BE SOLVED: To execute interruption processing in a proper order according to a requested schedule in an information processor. <P>SOLUTION: When an interruption controller 2 detects interruption signals corresponding to at least two kinds of interruption processing, the interruption controller 2 selects at least the two kinds of interruption processing one by one in the order and issues an interruption request corresponding to the selected interruption processing to a central processing unit (CPU) 1. The interruption controller 2 especially selects second interruption processing prior to first interruption processing when required time (time from the detection of the interruption signals to end of the interruption processing) for the second interruption processing, of at least the two kinds of detected interruption processing is shorter than a difference between processing start time (time from the detection of the interruption signals to start of the interruption processing) and start request time of the first interruption processing, of at least the two kinds of detected interruption processing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
