Abstract
Recent demand on more advanced functionalities in mobile devices has led to a drastic increase in power consumption of the device. Therefore, heat dissipation has become a major concern. To effectively overcome the thermal barrier based on the surface temperature of mobile devices, we propose a surface temperature-aware thermal management (STaTM) technique to be incorporated into a mobile application processor (AP), which plays a key role in the heat management of the mobile device. The proposed STaTM enables the AP to maximize the energy efficiency using accuracy-enhanced rapid surface temperature estimation. Experimental results show that the proposed solution achieves an average performance improvement of 14.2% when compared to conventional thermal management techniques.
