N2 - Abstract: In an Multi-Processor system-on-Chip (MP-SoC) environment, a customized run-time
management layer should be incorporated on top of the basic Operating System services to alleviate
the run-time decision-making and to globally optimise costs (e.g. energy consumption) across
all active applications, according to application constraints (e.g. performance, user requirements)
and available platform resources. To that end, to avoid conservative worst-case assumptions,
while also eliminating large run-time overheads on the state-of-the-art RTOS kernels, a
Pareto-based approach is proposed combining a design-time application and platform exploration
with a low-complexity run-time manager. The design-time exploration phase of this approach is the
main contribution of this work. It is also substantiated with two real-life applications (image processing
and video codec multimedia). These are simulated on MP-SoC platform simulator and used
to illustrate the optimal trade-offs offered by the design-time exploration to the run-time manager
