ABSTRACT
This paper proposes a novel approach to solve the allocation and scheduling problem for variable voltage/frequency MPSoCs, which minimizes overall system energy dissipation. Optimality of derived system configurations is guaranteed while the computation efficiency of the optimizer allows to solve problem instances that were traditionally considered beyond reach for exact solvers (optimality gap). Furthermore, this paper illustrates the development- and run-time software infrastructures that assist the user in developing applications and implementing optimizer solutions. The proposed approach guarantees a high level of power, performance and constraint satisfaction predictability as from validation on the target platform, thus bridging the abstraction gap.
