Analysing PPU programs for stalls
Has anyone had any experience using any simulators to analyse their PPU code for stalls, pipeline or otherwise?
I see there's tools on IBM's alphaworks site which look potentially useful. I'm particularly interesting in analysing the performance of some altivec code that executes on the PPU. A lot of stuff seems geared towards the SPUs. Failing that, has anyone got a good cheat sheet or tips guide that I could use to inspect my PPU vectorised code for stalls? Thanks. |

I think CELL simulator is the only tool that can do this.
CBE programming handbook: Appendix A. PPE Instruction Set and Intrinsics http://www-01.ibm.com/chips/techlib/...AGX16&S_CMP=LP some notes about profiling: http://www-01.ibm.com/chips/techlib/...AGX16&S_CMP=LP |
