Re: [Gems-users] Cache Insertion

["Mike Marty" <mike.marty@xxxxxxxxx>]

Each coherence protocol, specified by the .sm files, controls how blocks are inserted into the cache.  The "SMP" protocols have private L1 and L2 caches controlled by a single -cache.sm cache controller.  These protocols have exclusive L1/L2 caching.  Many of the "CMP" protocols, with separate -L1cache.sm and -L2cache.sm files, use inclusive L1/L2 caching.

The cache replacement policy is in the Ruby C++ code (CacheMemory.h)

I have been looking through the code for Ruby to try and find where in
the code new blocks are inserted.  I have had little success so far.  Is
this something that is done by Simics or does Ruby control its own
insertion?  Maybe I'm completely off base here?
