CACHE UTILIZATION USING A ROUTER BUFFER

Abstract

Network on chip (NOC) is used to connect Multiple Cores in a tiled multicore Processor. Here each core is connected to L1 cache where LLC (L2) is shared by the entire core. The data in the Last Level Cache slices can be accessed by multiple cores simultaneously and results in congestion at the LLC and increases the access time .So in order to find a solution to this problem, Propose a congestion management Technique in the LLC that contains NOC Router with small storage (Router Buffer Cache) to keep a copy of heavily shared cache blocks. The simulation of the Multicore system can be done by Gem5 tool and evaluate its effectiveness by running a set of parallel benchmarks , Thereby Reducing the LLC access Time “
