Hi Jason, Thank you for you reply. What you are suggesting is to model the Dram Cache similar to a memory object, say main memory which takes requests of 64 bytes but stores at a different granularity. Can you direct me as to where do I need to look for this change??
Also is making cacheline size local to each cache is difficult to update?? Please share your views as to which one would be a better option to go ahead.
