    • Breaking replay dependency loops in a processor using a rescheduled replay queue. The processor comprise a replay queue to receive a plurality of instructions, and an execution unit to execute the plurality of instructions. A scheduler is coupled between the replay queue and the execution unit. The scheduler speculatively schedules instructions for execution and increments a counter for each of the plurality of instructions to reflect the number of times each of the plurality of instructions has been executed. The scheduler also dispatches each instruction to the execution unit either when the counter does not exceed a maximum number of replays or, if the counter exceeds the maximum number of replays, when the instruction is safe to execute. A checker is coupled tot he execution unit to determine whether each instruction has executed successfully. The checker is also coupled to the replay queue to communicate to the replay queue each instruction that has not executed successfully.
    • 使用重新安排的重播队列在处理器中重新播放依赖循环。 处理器包括用于接收多个指令的重播队列,以及执行多个指令的执行单元。 调度器耦合在重播队列和执行单元之间。 调度器推测性地调度用于执行的指令,并且为多个指令中的每一个递增计数器,以反映多个指令中的每一个已被执行的次数。 当计数器不超过最大重放次数时,或者当计数器超过最大重放次数时,当指令执行安全时,调度器也将每条指令分派给执行单元。 检查器与执行单元相连以确定每个指令是否已成功执行。 检查器还耦合到重播队列,以便与未执行成功的每个指令通信给重播队列。
