Caches consume a significant amount of energy in modern microprocessors. To design an energy-efficient microprocessor, it is important to optimize cache energy consumption. High-performance microprocessors employ cache write-through policy for performance improvement and at the same time achieving good tolerance to soft errors in on-chip caches. Write-through policy also consumes large power due to the increased access to caches in different level during write operation. In this paper, the authors propose an efficient low power cache design referred to as way-tagged cache using pre-computation logic.
