Abstract

QoS is not intrinsic in most current NoC solutions, although it is crucial for global predictability and design reuse. Therefore, the current work presents a novel approach that borrows several concepts of DiffServ technology from Internet networks and adapts them to NoCs. This novel implementation based on connection-less communication improves the compromise between guaranteeing different traffic requirements and resource utilization, which is not efficiently granted in connection-oriented techniques, and provides a better scalability than the previous ones.
