摘要: A processor includes a core and an event-based sampler. The core includes logic to execute and retire an instruction. The event-based sampler includes logic determine a subset of a plurality of execution data of the processor from a register. The register includes bits specifying a subset of execution data. The event-based sampler further includes logic to selectively collect the determined subset of execution data upon retirement of the instruction and to store the selectively collected execution data.
