Performance Evaluation of Dynamic Cell Allocation Cache Using Cycle Accurate Simulator

Abstract

Multi-core processors are widely used to improve performance of computer systems. To achieve both high performance and low power consumption, we propose Cell-allocation cache. It allocates cache spaces called 'Cell' which is smaller than a way and dynamically assigns it to a core. However, it is only evaluated with trace-driven simulation, so evaluations of execution speed and energy consumption in realistic environments are not presented. In this paper, we implement Cell-allocation cache on the cycle accurate simulator Gem5 and evaluates more detailed performance. We also propose evaluation methodology by mixing plural benchmark programs to evaluate performance under unbalanced load works.
