Abstract
Method and apparatus for completing atomic instructions in a microprocessor may be provided by identifying from a program-ordered Instruction Completion Table (ICT) a last entry in a completion window of instructions for completion in a current clock cycle of a processor; in response to determining that the last entry includes an atomic instruction that straddles the completion window: excluding the last entry from completion during the current clock cycle; completing instructions in the completion window for the current clock cycle; and shifting the completion window to include the last entry and a next entry adjacent to the last entry in the ICT in a next clock cycle.
