摘要： A processor and method are described for implementing performance monitoring using a fixed function performance counter. For example, one embodiment of an apparatus comprises: a fixed function performance counter to decrement or increment upon occurrence of an event in the processing device; a precise event based sampling (PEBS) enable control communicably coupled to the fixed function performance counter; a PEBS handler to generate and store a PEBS record comprising architectural metadata defining a state of the processing device at a time of generation of the PEBS record; and a non-precise event based sampling (NPEBS) module communicably coupled to the PEBS enable control and the PEBS handler, the NPEBS module to cause the PEBS handler to generate the PEBS record for the event upon the fixed function performance counter reaching a specified value.
