Hi, Korey
Thank you so much for your help. I really appreciate it.

so it's a few simple things you can do to dump stats at a certain
interval. I adopted this from the checkpoint (?) dumping code and
implemented it in the SimpleCPU.
(1) src/simple/base.cc: In the constructor add these lines:
Tick when = ticks(p->start_stats);
Tick repeat = ticks(p->sample_period);
printf("Stats starting @ %i w/period of %i.\n", (int) when,
(int) repeat);
Stats::StatEvent(true, true, when, repeat);
You need to substitute the right values for the when/repeat variables.
*NOTE: DEPENDING ON YOUR CONFIG 1 cycle might equal 500 ticks. There
is a email about a few weeks back that describes how to make a 1:1
correlation between cycles and ticks.
Make sure these header files available:
#include "sim/stats.hh"
#include "sim/system.hh"
#include "sim/stat_control.hh"
(2) I print out headers so that I know that there stats for each
sample. In src/base/stats/text.cc add lines to the Text::output()
function to mark what stat sample you are on. My function looks like
this:
Text::output()
{
using namespace Database;
static int sample = 0;
ccprintf(*stream, "\n---------- Begin Simulation Statistics :
Sample %i ----------\n", sample);
stat_list_t::const_iterator i, end = stats().end();
for (i = stats().begin(); i != end; ++i)
(*i)->visit(*this);
ccprintf(*stream, "\n---------- End Simulation Statistics : Sample
%i ----------\n", sample++);
stream->flush();
}
Anyway, I hope that helps what you are doing.
