New approaches to DVFS in mobile MPSoC for power-, thermal-efficiency
and reliability
Abstract
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.
