The authors introduce a new non-intrusive on-chip cache-tuning hardware module capable of accurately predicting the best configuration of a configurable cache for an executing application. Previous dynamic cache tuning approaches change the cache configuration several times as part of the tuning search process, executing the application using inferior configurations and temporarily causing energy and performance overhead. The introduced tuner uses a different approach, which non-intrusively collects data on addresses issued by the microprocessor, analyzes that data to predict the best cache configuration, and then updates the cache to the new best configuration in \"One-shot,\" without ever having to examine inferior configurations.
