Energy consumption has become a critical issue in many high performance microprocessors. Chip multiprocessors, CMP is only way to build high performance microprocessors. Most of the power dissipated in microprocessor is contributed by on-chip cache memories. This paper includes a CMP architecture in which way tagging is applied to cache memories for reducing energy consumption. Two core processors architecture with a shared L3 cache has been selected. For each core, the way information of L2 cache is maintained in the L1 cache and that of L3 cache in L2 cache.
