A Novel Flow Control Mechanism to Avoid Multi-Point Progressive Blocking in Hard Real-Time Priority-Preemptive NoCs
2020
2020 IEEE Real-Time and Embedded Technology and Applications Symposium (RTAS)
The recently uncovered problem of multi-point progressive blocking (MPB) has significantly increased the complexity of schedulability analysis of priority-preemptive wormhole networks-on-chip. While state-of-the-art analysis is currently deemed safe, there is still significant inherent pessimism when it comes to considering backpressure issues caused by downstream indirect interference. In this paper, we attempt to simplify the problem by considering a novel flow control protocol that can avoid
