| Abstract(in English) | Network-on-Chip (NoC) is expected to be used for the next-generation interconnection between many processing cores due to a high scalability compared to conventional buses. To satisfy QoS and real-time constraints required for many-core processors, priority-aware NoCs have been studied recently However, adding priority control for NoCs introduces priority inversion problems, in which a high priority packet is blocked by a low priority packet. In this paper, we introduce a counter to each router physical channel to detect the priority inversions. We also introduce a priority-inheritance mechanism to resolve them. The evaluation results show that the priority inversions are significantly reduced. |
