A power-efficient migration mechanism for D-NUCA caches
D-NUCA L2 caches are able to tolerate the increasing wire delay effects due to technology scaling thanks to their banked organization, broadcast line search and data promotion/demotion mechanism. Data promotion mechanism aims at moving frequently accessed data near the core, but causes additional accesses on cache banks, hence increasing dynamic energy consumption. We shown how, in some cases, this migration mechanism is not successful in reducing data access latency and can be selectively and dynamically inhibited, thus reducing dynamic energy consumption without affecting performances.
