In this work, we present a mechanism for a global and dynamic admission control in NoCs dedicated to real-time systems. It introduces an overlay network to synchronize transmissions using arbitration units called Resource Managers (RMs), which allows a global and work-conserving scheduling. We present a formal worst-case timing analysis for the proposed mechanism and demonstrate that this solution not only exposes higher performance in simulation but, even more importantly, consistently reaches smaller formally guaranteed worst-case latencies than TDM for realistic levels of system's utilization. Our mechanism does not require the modification of routers and therefore can be used together with any architecture utilizing non-blocking routers.en0167-92602017571582Dynamic admission controlNetworks-on-ChipReal-time systemsSafety-critical multicoresShared resourcesJournal Article10.1016/j.vlsi.2016.10.015Other
