Abstract

A method and circuit for a data processing system (200) provide a processor-based partitioned priority blocking mechanism by storing interrupt identifiers, partition identifiers, thread identifiers, and priority levels associated with accepted interrupt requests in special purpose registers (35-38) located at the processor core (26) to enable quick and efficient interrupt priority blocking on a partition basis.
