Heterogeneous MPSoCs for Mixed Criticality Systems: Challenges and Opportunities
Abstract
Due to their cost, performance, area, and energy efficiency, MPSoCs offer
appealing architecture for emerging mixed criticality systems (MCS) such as
driverless cars, smart power grids, and healthcare devices. Furthermore,
heterogeneity of MPSoCs presents exceptional opportunities to satisfy the
conflicting requirements of MCS. Seizing these opportunities is unattainable
without addressing the associated challenges. We focus on four aspects of MCS
that we believe are of most importance upon adopting MPSoCs: theoretical model,
interference, data sharing, and security. We outline existing solutions,
highlight the necessary considerations for MPSoCs including both opportunities
they create and research directions yet to be explored.
