Design and implementation of power-aware virtual memory

Despite constant improvements in fabrication technology, hardware components are consuming more power than ever. With the ever-increasing demand for higher performance in highly-integrated sys-tems, and as battery technology falls further behind, managing en-ergy is becoming critically important to various embedded and mo-bile systems. In this paper, we propose and implement power-aware virtual memory to reduce the energy consumed by the memory in re-sponse to workloads becoming increasingly data-centric. We can use the power management features in current memory technology to put individual memory devices into low power modes dynamically un-der software control to reduce the power dissipation. However, it is imperative that any techniques employed weigh memory energy sav-ings against any potential energy increases in other system compo-nents due to performance degradation of the memory.
