Energy-Delay-Product-aware DVFS is a widely-used technique that improves energy efficiency by dynamically adjusting the frequencies of cores. Further, for multithreaded applications, barrier-aware DVFS is a method that can dynamically tune the frequencies of cores to reduce barrier stall times and achieve higher energy efficiency. In both forms of DVFS, frequencies of cores are reduced from the maximum value to achieve better energy efficiency. TFET devices operate at energy efficiencies that cannot be achieved by CMOS devices. This advantage of TFET devices can be exploited in the context of multi-core processors by replacing some of the CMOS cores with energy efficient TFET alternatives.
