Hi Neha, For this thread, and all other threads where people want to evaluate various memory types for the L2, L3, LLC, my pragmatic suggestion would be to start by getting this patch ready to go out:
http://reviews.gem5.org/r/1809/ Once that is in place, the cache captures different read and write latencies, and models the contention and waiting time for the banks. I would argue that for most cases this is probably a sufficient model for the performance impact (but I¹d be keen to hear if anyone disagrees). The next step would be to add sufficient stats to capture how many reads/writes and how long time is spent in various states (idle, refresh etc), and use these stats for a high-level power model. At this point, I do not see how adding more detailed memory models would help. Could someone elaborate on why they think this is a good idea?
