INTERRUPT CONTROLLER, INTERRUPT CONTROL METHOD, DEVICE WITH INTERRUPT CONTROLLER, INTERRUPT CONTROL PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an interrupt controller, an interrupt control method, a device with an interrupt controller, an interrupt control program, and a recording medium that can easily realize multiple interrupts of a high degree of freedom and can set a priority level of an interrupt of each device irrespective of device configuration.;SOLUTION: The interrupt controller for permitting multiple interrupts has saving means (S1) for saving a current interrupt level, specifying means (S2, S3) for selecting a level handler and specifying an interrupt handler by means of the level handler and an interrupt factor, starting means (S4) for starting an interrupt program corresponding to the specified interrupt handler, and recovering means (S5, S6) for clearing the interrupt factor handled by the start of the interrupt program and recovering the interrupt level saved in the saving means.;COPYRIGHT: (C)2005,JPO&NCIPI
