| Summary: | Multiprocessor Systems-on-Chips (MPSoCs) offer
superior performance while maintaining flexibility and reusability
thanks to software oriented personalization. While most
MPSoCs are today heterogeneous for better meeting the targeted
application requirements, homogeneous MPSoCs may become
in a near future a viable alternative bringing other benefits
such as run-time load balancing and task migration. The work
presented in this paper relies on a homogeneous NoC-based
MPSoC framework we developed for exploring scalable and
adaptive on-line continuous mapping techniques. Each processor
of this system is compact and runs a tiny preemptive operating
system that monitors various metrics and is entitled to take
remapping decisions through code migration techniques. This
approach that endows the architecture with decisional capabilities
permits refining application implementation at run-time according
to various criteria. Experiments based on simple policies are
presented on various applications that demonstrate the benefits
of such an approach. |
