Re: [Gems-users] About cache replacement policy in CMP

[Luke Yen <lyen@xxxxxxxxxxx>]

   For each CMP chip, each private L1 cache (instruction and data) has its
own LRU stack, and the shared unified L2 cache has a single LRU stack.
The L2 LRU stack is potentially updated by all the cores on the CMP chip.
