To alleviate the complex communication problems that arise as the number of on-chip components increases, network-on-chip (NoC) architectures have been recently proposed to replace global interconnects. In this paper, we first provide a general description of NoC architectures and applications. Then, we enumerate several related research problems organized under five main categories: Application characterization, communication paradigm, communication infrastructure, analysis, and solution

Finally, we address the interactions among these research problems and put the NoC design process into perspective. Index Terms-Energy and power consumption, multiprocessor systems-on-chip (MPSoCs), networks-on-chip (NoCs), on-chip communication.
