ABSTRACT:
To expand the interrupt capabilities of a microprocessor system without restructing system architecture, intermediate levels of priority are created for a given interrupt request. Plural interrupts can be handled on one interrupt request line to thereby permit execution of a number of functions that is greater than the number of interrupt lines. A system controller which provides this capabitlity can monitor the various functions during their execution, as well as arbitrate among plural interrupts so as to maintain the priority which has been assigned to them.
