Hello all, I'd like to know if the gem5 community would like to have a TAGE branch prediction in gem5. In my branch it seems to be working, so if you give me a positive feedback I may spend some spare time to rebase and test the patch over mainstream.
More specifically, I took the CBP2016 winner and removed local prediction tables. This specific version is called TAGE-GSC (Global Statistical Corrector) and should go to src/cpu/pred/tage-gsc.hh. This file is functionally equivalent to the original CBP2016 winner and can be compared against it without modification. Then, a glue code was implemented in src/cpu/pred/TAGE.hh and src/cpu/pred/TAGE.cc, making tage-gsc.hh to work in gem5. I validated the gem5 implementation by comparing the predictor at fetch with a validator at commit. The prediction tables must be the same. Regards, -- Fernando A.
