• Process variations yield the asymmetry on core performance in many-core processors. Adaptive voltage scaling can hide the variations, but that results in the different thermal characteristics of cores. By using the thermal characteristics, the efficiency of energy optimization and temperature management can be improved. Experiments showed that the proposed dynamic voltage frequency scaling consumes up to 25.2 % less energy than the existing thermal management technique while remaining the ratio of peak temperature violations under 1%.
