- The delay upper-bound analysis problem is of fundamental importance to real-Time applications in Network-on-Chips (NoCs). In the paper, we revisit two state-of-The-Art analysis models for real-Time communication in wormhole NoCs with priority-based preemptive arbitration and show that the models only support specific router architectures with large buffer sizes. We then propose an extended analysis model to estimate delay upper-bounds for all router architectures and buffer sizes by identifying and analyzing the differences between upstream and downstream indirect interferences according to the relative positions of traffic flows and taking the buffer influence into consideration. Simulated evaluations show that our model supports one more router architecture and applies to small buffer sizes compared to the previous models.
