Summary:PURPOSE:To improve the processing efficiency of an information processor by optimizing an interrupt level. CONSTITUTION:An interrupt level storage means 10 stores the interrupt level arbitrarily set corresponding to an interrupt request signal. Receiving plural interrupt request signals, an interrupt level processing means 12 outputs the interrupt level signal having highest interrupt level order corresponding to the interrupt level stored in the interrupt level storage means 10. The information processor performs the interrupt processing based on the interrupt level signal. An interrupt level operation means designating the interrupt level corresponding to the state of a control device, a storage means storing the interrupt level transmitted from the interrupt level operation means, and an interrupt processing means outputting the interrupt level signal having highest interrupt order corresponding to the interrupt level stored in the storage means.
