CCNoC: Cache-Coherent Network on Chip for Chip Multiprocessors

As the number of cores in chip multiprocessors(CMPs) increases,cache coherence protocol has become a key issue in integration of chip multiprocessors.Supporting cache coherence protocol in large chip multiprocessors still faces three hurdles:design complexity,performance and scalability.This paper proposes Cache Coherent Network on Chip(CCNoC),a scheme that decouples cache coherency maintenance from processors and shared L2 caches and implements it completely in network on chip to free up processors and sha...
