Cycles-Per-Instruction (CPI) stacks provide intuitive and insightful performance information to software developers. Performance bot-tlenecks are easily identified from CPI stacks, which hint towards software changes for improving performance. Computing CPI stacks on contemporary superscalar processors is non-trivial though because of various overlap effects. Prior work proposed a CPI counter architecture for computing CPI stacks on out-of-order processors. The accuracy of the obtained CPI stacks was evaluated previously, however, the hardware overhead analysis was not based on a detailed hardware implementation. In this paper, we implement the previously proposed CPI counter architecture in hardware and we find that the previous design can...
