A CMP Oriented Variable-Way Hybrid Cache
Zhang Min-xuan · Dianzi xuebao · 2011
We propose a CMP oriented variable-way hybrid cache mechanism,named CMP-VH,based on V-Way Cache.CMP-VH turns the last level cache into an optimized private/shared organization.The tag array is private,while the data array is private and shared organized.In CMP-VH,we use reuse information for cache line replacement,and provide implicit and explicit partitioning mechanisms for shared data region.The simulation result of parallel workload SPLASH-2 shows that CMP-VH excelled the pure private or shared cache.
