    Cache replacement policy for Nehalem/SNB/IB?

    wujj123456

      I am working on a simple cache simulator for recent Intel processors.  It's used to provide profiling info for our cache optimization.  Therefore, I don't need it to be very very accurate, but it can't be too different from the facts either. 

       

      I didn't find much information about cache line replacement policy.  Does anyone know where I can look up these info?  I am mostly interested in L2 and L3 cache replacement policies.  Someone online said it's PLRU.  Can anyone confirm that?  If yes, is it a tree-PLRU or bit-PLRU?

       

      Thanks.
