Re: [Gems-users] Cache design in GEMS

Ruby implements only writeback L1s

 

The Opal cache.C and cache.h should be ignored for the most part.

 

To implement a victim cache, you will likely need to add this to the SLICC protocol specifications.

Subject: [Gems-users] Cache design in GEMS

 

Dear list,

 

I just recently start using GEMS for my research project on new CMP cache hierarchy designs. In my simulation I'll be using both ruby and opal. I was trying to modify code that is related to the cache design, for example, insert a victim cache between L1 and L2. However I found in ruby/system a CacheMemory.h, also in opal/system cache.C and cache.h files. I am wondering which one(s) should I be looking at? Also, where in the code is the write-back/write-through policy specified for L1 and L2?

 

Your comments are greatly appreciated. Thanks a lot!!
