From 1028c03320c6c7822b8f5a32da2297c1be2d1487 Mon Sep 17 00:00:00 2001 From: Curtis Dunham Date: Fri, 9 May 2014 18:58:47 -0400 Subject: cpu: add more instruction mix statistics For the o3, add instruction mix (OpClass) histogram at commit (stats also already collected at issue). For the simple CPUs we add a histogram of executed instructions --- src/cpu/simple/base.cc | 12 ++++++++++++ src/cpu/simple/base.hh | 3 +++ 2 files changed, 15 insertions(+) (limited to 'src/cpu/simple') diff --git a/src/cpu/simple/base.cc b/src/cpu/simple/base.cc index 3adf6d27f..f022d05e0 100644 --- a/src/cpu/simple/base.cc +++ b/src/cpu/simple/base.cc @@ -286,6 +286,16 @@ BaseSimpleCPU::regStats() .prereq(dcacheRetryCycles) ; + statExecutedInstType + .init(Enums::Num_OpClass) + .name(name() + ".op_class") + .desc("Class of executed instruction") + .flags(total | pdf | dist) + ; + for (unsigned i = 0; i < Num_OpClasses; ++i) { + statExecutedInstType.subname(i, Enums::OpClassStrings[i]); + } + idleFraction = constant(1.0) - notIdleFraction; numIdleCycles = idleFraction * numCycles; numBusyCycles = (notIdleFraction)*numCycles; @@ -532,6 +542,8 @@ BaseSimpleCPU::postExecute() } /* End power model statistics */ + statExecutedInstType[curStaticInst->opClass()]++; + if (FullSystem) traceFunctions(instAddr); diff --git a/src/cpu/simple/base.hh b/src/cpu/simple/base.hh index ad672da6c..47034c300 100644 --- a/src/cpu/simple/base.hh +++ b/src/cpu/simple/base.hh @@ -283,6 +283,9 @@ class BaseSimpleCPU : public BaseCPU Stats::Scalar numBranchMispred; /// @} + // instruction mix histogram by OpClass + Stats::Vector statExecutedInstType; + void serializeThread(std::ostream &os, ThreadID tid); void unserializeThread(Checkpoint *cp, const std::string §ion, ThreadID tid); -- cgit v1.2.3
