PURPOSE:To perform the interruption control at high speed and with high efficiency and to obtain high real time response properties, by saving a control mechanism to a newly provided save mechanism when an interruption is produced. CONSTITUTION:A control mechanism 2 which controls a state saving area when an interruption is produced saves the interruption to a save mechanism 3. Then the mechanism 2 is set again to show the next saving area for the next interruption. Then the state of generation of an interruption is saved to a state saving area 1 in accordance with the mechanism 2 saved to the mechanism 3. Therefore if another interruption is newly produced under such conditions, a normal operation is secured with no destruction of the preceeding saving area since the mechanism 2 is set again.
