METHOD AND PROCESSOR FOR PROCESSING INTERRUPT IN PROCESSOR, AND DATA PROCESSING SYSTEM BY USING HISTORY INFORMATION

摘要

PURPOSE: A method and a processor for processing an interrupt in a processor, and a data processing system are provided to minimize a processing delay generated by storing/recovering an architected state in response to the interrupt, and to improve interrupt handling process. CONSTITUTION: The processor includes at least one executing unit(204), an ISU(Interrupt Sequencing Unit)(202) combined to at least one executing unit, and an interrupt handler prediction table combined to the ISU. The interrupt handler prediction table predicts one execution among multiple interrupt handlers based on history of the interrupt handler execution kept in the interrupt handler prediction table by responding to interrupt reception of the processor. The ISU orders at least one executing unit to execute the predicted interrupt handler.
