Several propositions of NoC architectures claim providing Quality-of-Service (QoS) guarantees, which is essential for e.g. real time and multimedia applications. The state-of-art in NoC literature provides QoS at design time, using circuit switching and/or priority-based scheduling. Both methods optimize a given network template to achieve the QoS requirements after traffic generation and network simulation. However, modern SoCs may execute applications not devised at design time, and these may easily have its QoS requirements violated by a previously fixed NoC structure.
