Next generation multiprocessor systems-on-chip (MPSoCs) are expected to contain numerous processing elements, interconnected via on-chip networks, executing real-time applications. It is anticipated that runtime optimization algorithms which dynamically adjust system parameters with the purpose of optimizing the system's operation, will be embedded in the system software and/or hardware. In this paper, we present a methodology for simulating and evaluating system-level optimization algorithms, demonstrated by the case of on-chip dynamic task allocation applied to generic MPSoC architectures. Through this methodology, we are able to show that dynamic, system-level bidding-based task allocation can improve system performance, when compared to a round robin allocation, in popular MPSoC applications.
