Clustered Look Ahead Prefetching Mechanism In Near Memory Processor

R. Meera, T. Perarasi, R. Ezhilarasi

Abstract: Near memory processing is a recent solution to overcome the challenges imposed by memory wall. The solution can bridge the performance gaps between processing and memory speeds. Thus a light weight practical memory side prefecther is proposed to improve the performance of near memory processor. The proposed prefetcher exploit the system performance by bringing data from lower level memory before they are needed. The proposed clustered look ahead prefetching is used to predict the future data reference and determine which data are to be prefetched earlier based on the prediction. The proposed CLAP mechanism is fixed in a near memory processor which makes the system performance efficient and reduce the energy consumption to prolong the lifetime of the battery. Therefore the near memory processor reduce the delay and increase the speed of the DRAM system.
