DETERMINING EACH STALL REASON FOR EACH STALLED INSTRUCTION WITHIN A GROUP OF INSTRUCTIONS DURING A PIPELINE STALL
摘要：
During a pipeline stall in an out of order processor, until a next to complete instruction group completes, a monitoring unit receives, from a completion unit of a processor, a next to finish indicator indicating the finish of an oldest previously unfinished instruction from among a plurality of instructions of a next to complete instruction group. The monitoring unit receives, from a plurality of functional units of the processor, a plurality of finish reports including completion reasons for a plurality of separate instructions. The monitoring unit determines at least one stall reason from among multiple stall reasons for the oldest instruction from a selection of completion reasons from a selection of finish reports aligned with the next to finish indicator from among the plurality of finish reports. Once the monitoring unit receives a complete indicator from the completion unit, indicating the completion of the next to complete instruction group, the monitoring unit stores each determined stall reason aligned with each next to finish indicator in memory.
摘要（中）：

在处理器处于不规则处理器的流水线停止期间，直到完成指令组的下一个完成为止，监视单元从处理器的完成单元接收到指示完成以前未完成的指令的完成的下一个完成指示， 下一个完成指令组的多个指令。 监视单元从处理器的多个功能单元接收多个完成报告，包括多个单独指令的完成原因。 从多个完成报告中的与下一个完成指示符对齐的完成报告的选择完成原因的选择中，监视单元从最多的指令的多个失败原因中确定至少一个失败原因。 一旦监视单元从完成单元接收到完整的指示符，指示完成下一个完成指令组，则监视单元将每个确定的停顿原因与每个下一个完成指示符对准在存储器中。
