摘要： A method and system for monitoring the performance of a instruction pipeline is provided. The processor may contain a performance monitor for monitoring for the occurrence of an event within a data processing system. An event to be monitored may be specified through software control, and the occurrence of the specified event is monitored during the execution of an instruction in the execution pipeline of the processor. A particular instruction may be specified to execute within a threshold time for each stage of the instruction pipeline. The specified event may be the completion of a single tagged instruction beyond the specified threshold interval for a stage of the instruction pipeline. The performance monitor may contain a number of counters for counting multiple occurrences of specified events during the execution of multiple instructions, in which case the specified events may be the completion of tagged instructions beyond a threshold interval for any stage of the multiple stages of the execution pipeline. As the instruction moves through the processor, the performance monitor collects the events and provides the events for optimization analysis.

摘要： A method and system for debugging the execution of an instruction within an instruction pipeline is provided. A processor in a data processing system contains instruction pipeline units. An instruction may be tagged, and in response to an instruction pipeline unit completing its processing of the tagged instruction, a stage completion signal is asserted. An execution monitor external to the pipelined processor monitors the stage completion signals during the execution of the tagged instruction. The execution monitor may be a logic analyzer that displays the stage completion signals in real-time on a display device of the execution monitor. An instruction to be tagged may be selected based upon an instruction selection rule, such as the address of the instruction.
