Predictive Models for Multimedia Applications Power Consumption Based on Use-Case and OS Level Analysis
Power management at any abstraction level is a key
issue for many mobile multimedia and embedded applications.
In this paper a design workflow to generate system-level power
models will be presented, tailored to support quantitative runtime
power optimization policies to be implemented within
an operating system. The approach we followed to derive
power models is strongly use-case oriented. Starting from a
comprehensive general and accurate model of a representative
architecture for embedded applications (including a multi core
MPSoC, accelerators, interfaces and peripherals), a methodology
to derive compact models is presented, based upon the distinctive
characteristics of the selected use cases. The methodology to
generate such model, whose exploitation is foreseen within a
power manager working at the OS level, is the focus of the paper.
The value and accuracy of the approach is quantitatively and
statistically justified through extensive experiments carried out
on a development board designed for multimedia applications
