Power efficient data cache designs

We investigate some power efficient data cache designs that try to significantly reduce the cache energy consumption, both static and dynamic, with a minimal impact in performance. The basic idea is to combine different threshold voltages with different cache organizations that provide different levels of performance. Multibanked organizations in combination with different approaches to allocate data to cache banks are explored. Some of the resulting cache architectures are shown to provide a good tradeoff between power and performance.Peer Reviewe
