A portable infrastructure supporting global scheduling of embedded real-time applications on asymmetric MPSoCs

Multiprocesso system-on-chip (MPSoC) open notable perspectives in the design of highly targeted embedded solutions for real-time multi-tasking applications. The eterogeneity of available platforms, however, often hinders plain applicability of efficient schedulng policies, particularly in the case of loosely-coupled architectures which do not provide any support for inter-processor task migration. In this paper we present a portable software nfrastructure addressing the global scheduling of periodic real-time tasks on such platforms. We show that global scheduling policies, under the restricted-migration model, are applicable also on asymmetric multiprocessing systems and experimentally evaluate the validity of the approach using different FPGA-based confiurations that recall manifold architectures of commercial MPSoCs.
