A cache-coloring based technique for saving leakage energy in multitasking systems

Abstract: There has been a significant increase in leakage energy dissipation of CMOS circuits with each technology generation. Further, due to their large size, last level caches (LLCs) spend a large fraction of their energy in the form of leakage energy and hence, addressing this has become extremely important to meet the challenges of chip power budget. For addressing this, several techniques have been proposed. However, most of these techniques require offline profiling and hence cannot be used for real-life systems ...
