Zusammenfassung:Method and apparatus for a completion mechanism for a microprocessor are provided by identifying entries in a section of an Instruction Completion Table (ICT) that are marked as ready to complete via corresponding Ready to Complete (RTC) status bits; determining a tail pointer indicating a start of the entries in the ICT that are ready for completion; determining a head pointer that indicates an end of the entries in the ICT that are ready for completion; completing instructions included in the entries between the tail pointer and the head pointer; and updating the tail pointer to a value of the head pointer for a subsequent instruction completion round.
