Interrupt control method, interrupt control apparatus and interrupt control medium

摘要

Once accepting an interrupt, the control is such as to not accept any interrupt including that highest priority within the group to which the interrupt about to be processed belongs by referring to the interrupt management table. Then the vector number for the highest priority in the group from among the received interrupts is selected. Then the processing of a handler for the selected vector number is executed. The priority of the executed interrupt processing is reset to the lowest priority in the group.
