Modern mobile devices come equipped with heterogeneous multi-processor system-on-chip (MPSoC) consisting of different types of cores such as CPU and GPU to cater for performance requirement of different types of applications. These MPSoCs also supports dynamic voltage and frequency scaling (DVFS) to reduce dynamic power consumption, which retrospectively affects the peak temperature of the multi-processors on the chip as well. In this poster presentation, we introduce three novel approaches to DVFS in mobile MPSoCs such that the executing applications can meet the performance requirement while consuming less power, reducing peak temperature and improving thermal side-channel security and reliability in terms of lifespan of the device.
