Way-Predicting Set-Associative Cache for High Performance and Low Energy Consumption

摘要

This paper proposes a new approach using way prediction for achieving high performance and low energy consumption of set-associative caches. By accessing only a single cache way predicted, instead of accessing all the ways in a set, the energy consumption can be reduced. This paper shows that the way-predicting set-associative cache improves the ED (energy-delay) product by 60-70precent compared to a conventional set-associative cache.
