Abstract
A method and apparatus to monitor the performance of a processor. A performance specifier specifies a performance data corresponding to the performance. The performance data includes an event and an instruction causing the event. A tag generator is coupled to the performance specifier to generate a performance tag associated with the instruction. The performance tag is stored in a storage. A retirement performance monitor is coupled to the storage to extract the performance tag when the instruction is retired.
