Abstract
AbstractóLeakage energy has been estimated to increase by five-times with each CMOS technology generation and this is expected to become a major source of energy dissipation, especially in large last-level caches (LLCs). We present EnCache, a novel cache leakage energy saving scheme that uses a new micro-architecture component called profiling cache. With this hardware support, system software can accurately predict the cache usage and energy efficiency of a running program for 32 possible cache configurations and vary the ...
