From 248bd2bb62861c8d77de4c8cfab6c6392bd85049 Mon Sep 17 00:00:00 2001 From: Kevin Lim Date: Thu, 25 May 2006 17:01:48 -0400 Subject: Various branch predictor fixes/cleanup. It works more correctly now and supports both local and tournament predictors. cpu/o3/2bit_local_pred.cc: Branch predictor cleanup/fixup. Rename this to LocalBP. cpu/o3/2bit_local_pred.hh: Rename to LocalBP, update to support changes to BPredUnit, include comments. cpu/o3/alpha_cpu_builder.cc: Support extra parameters to the branch predictor. Now it takes in a parameter to tell it which branch predictor it is using, the local or the tournament predictor. cpu/o3/alpha_params.hh: Add in extra parameter for the branch predictor type. cpu/o3/bpred_unit.cc: Branch predictor fixup/cleanup. Rename it to BPredUnit. cpu/o3/bpred_unit.hh: Branch predictor fixup/cleanup. Now supports both the local and tournament predictors, and stores the branch predictor update state. cpu/o3/bpred_unit_impl.hh: Branch predictor overhaul. Now supports both the local and tournament predictors. cpu/o3/cpu_policy.hh: cpu/ozone/ozone_impl.hh: cpu/ozone/simple_impl.hh: Reflect the class name change. cpu/o3/decode_impl.hh: Be sure to set the predicted target as well so we don't squash twice. cpu/o3/tournament_pred.cc: cpu/o3/tournament_pred.hh: Fixes to the tournament predictor. cpu/ozone/simple_params.hh: Include parameter for the branch predictor type. python/m5/objects/AlphaFullCPU.py: python/m5/objects/OzoneCPU.py: Include the parameter for the branch predictor type. --HG-- extra : convert_revision : 34afebb3b40b47accb12558e439ee4cb03df5e64 --- python/m5/objects/OzoneCPU.py | 1 + 1 file changed, 1 insertion(+) (limited to 'python/m5/objects/OzoneCPU.py') diff --git a/python/m5/objects/OzoneCPU.py b/python/m5/objects/OzoneCPU.py index 3fca61e28..ea8b6b537 100644 --- a/python/m5/objects/OzoneCPU.py +++ b/python/m5/objects/OzoneCPU.py @@ -57,6 +57,7 @@ class DerivOzoneCPU(BaseCPU): commitWidth = Param.Unsigned("Commit width") squashWidth = Param.Unsigned("Squash width") + predType = Param.String("Type of branch predictor ('local', 'tournament')") localPredictorSize = Param.Unsigned("Size of local predictor") localCtrBits = Param.Unsigned("Bits per counter") localHistoryTableSize = Param.Unsigned("Size of local history table") -- cgit v1.2.3
