Energy Characterization of Hardware-Based Data Prefetching

This paper evaluates several hardware-based data prefetching techniques from an energy perspective, and explores their energy/performance tradeoffs. We present detailed simulation results and make performance and energy comparisons between different configurations. Power characterization is provided based on HSpice circuit-level simulation of state-of-the-art low-power cache designs implemented in deep-submicron process technology. This is combined with architecture-level simulation of switching activities in the memory system.
