The cache hierarchy of state-of-the-art - especially multicore - microprocessors consumes a significant amount of area and energy. A significant amount of research has been devoted especially to reducing the latter. One of the most important microarchitectural techniques proposed for the energy management is Dynamic Voltage Scaling (DVS). In DVS solutions, each cache operates at a number of different voltages. Most of the research in DVS techniques have been around how the voltages can be adjusted and tuned. In this paper, the authors depart from the use of DVS for energy conservation by examining static voltage assignments for caches.
