Hi, In my project I need to dump out the power profile (with time) for some benchmarks. In that case, I think I need to dump out the GEM5 statistics to McPAT for power calculation every a few cycles.
As I'm very new to GEM5, could anybody let me know where to start for dumping GEM5 statistics for every 100 cycles? Thanks a lot.
