Last level cache in chip multi-processors is shared by many cores; prefetchers should be fully simulated and evaluated before integrated in product. However, evaluation methodologies of proposed prefetchers vary from each other without unified simulation framework provided. This paper implements a prefetch simulation framework and evaluates seven important prefetchers, providing comprehensive evaluation methodology to newly proposed prefetchers. Moreover, we analyze the influence of storage cost and memory bandwidth quantitatively.
