From 287ea1a081c5dd3213069755dbbd3d7bf736bacc Mon Sep 17 00:00:00 2001 From: Andreas Hansson Date: Fri, 7 Sep 2012 12:34:38 -0400 Subject: Param: Transition to Cycles for relevant parameters This patch is a first step to using Cycles as a parameter type. The main affected modules are the CPUs and the Ruby caches. There are definitely plenty more places that are affected, but this patch serves as a starting point to making the transition. An important part of this patch is to actually enable parameters to be specified as Param.Cycles which involves some changes to params.py. --- src/mem/cache/tags/iic.cc | 2 ++ src/mem/cache/tags/iic.hh | 2 +- 2 files changed, 3 insertions(+), 1 deletion(-) (limited to 'src/mem/cache/tags') diff --git a/src/mem/cache/tags/iic.cc b/src/mem/cache/tags/iic.cc index d6ddf04a6..3fdc11e80 100644 --- a/src/mem/cache/tags/iic.cc +++ b/src/mem/cache/tags/iic.cc @@ -250,6 +250,8 @@ IIC::accessBlock(Addr addr, int &lat, int context_src) } } + // @todo: is hashDelay is really cycles, then + // multiply with period set_lat = set_lat * hashDelay + hitLatency; if (tag_ptr != NULL) { // IIC replacement: if this is not the first element of diff --git a/src/mem/cache/tags/iic.hh b/src/mem/cache/tags/iic.hh index 0c3ea7a13..fd63daff7 100644 --- a/src/mem/cache/tags/iic.hh +++ b/src/mem/cache/tags/iic.hh @@ -196,7 +196,7 @@ class IIC : public BaseTags const unsigned subMask; /** The latency of a hash lookup. */ - const unsigned hashDelay; + const Cycles hashDelay; /** The total number of tags in primary and secondary. */ const unsigned numTags; /** The number of tags in the secondary tag store. */ -- cgit v1.2.3
