Yeah, a tool called Montecito! ;-) I don't remember whether you were at the last Gelato meeting and whether you attended the PMU talk. If you didn't: I had some slides in there that showed how the IP-EAR can be used to get instruction-group issue traces which show you exactly how many stall-cycles there are between subsequent instruction-groups. Yes, that's a bit different from the static info you are looking for, but in many ways it's much better info, so it's real (measured) data and takes into affect all corner cases, including memory latency etc. --david -- Mosberger Consulting LLC, voice/fax: 510-744-9372, http://www.mosberger-consulting.com/ 35706 Runckel Lane, Fremont, CA 94536
