Network-on-Chip (NoC) is a preferred communication medium for massively parallel platforms. Fixed-priority based scheduling using virtual-channels is one of the promising solutions to support real-time traffic in on-chip networks. Most of the existing works regarding priority-based NoCs use a flit-level preemptive scheduling. Under such a mechanism, preemptions can only happen between the transmissions...
Many-core processors can provide the computational power required by future complex embedded systems. However, their adoption is not trivial, since several sources of interference on COTS many-core platforms have adverse effects on the resulting performance. One main source of performance degradation is the contention on the Network-on-Chip (NoC), which is used for communication among the compute...
Network-on-Chip (NoC) is a communication subsystem which has been widely utilized in many-core processors and system-on-chips in general. In order to execute time-critical applications on a NoC-based platform, the timing behavior of the network needs to be predicted during system design. One of the most important timing requirements is regarding schedulability, which refers to determining if a real-time...

Priority-based wormhole-switching has been proposed as a solution to handle real-time traffic in on-chip networks. In order to support real-time traffic, the predictability of end-to-end delays need to be guaranteed. Several deterministic schedulability analysis approaches for wormhole-switched networks have been proposed. These approaches calculate a single upper-bound of the response time of each...
