	abstract = {Kahn process networks (KPN) is a distributed model of computation used for describing systems where streams of data are transformed by processes executing in sequence or parallel. Autonomous processes communicate through unbounded FIFO channels in absence of a global scheduler. In this work, we propose a task-aware middleware concept that allows adaptivity in KPN implemented over a Network-on-Chip (NoC). We also list our ideas on the development of a simulation platform as an initial step towards creating fault-tolerance strategies for KPNs applications running on NoCs. In doing that, we extend our SACRE (Self-adaptive Component Run-time Environment) framework by integrating it with an open source NoC simulator, Noxim. We evaluate the overhead that the middleware brings to the the total execution time and to the total amount of data transferred in the NoC. With this work, we also provide a methodology that can help in identifying the requirements and implementing fault tolerance and adaptivity support on real platforms.},

	abstract = {We investigate and propose a number of different middleware approaches, namely virtual connector, virtual connector with variable rate, and request-based, which implement the semantics of Kahn Process Networks on Network-on-Chip architectures. All of the presented solutions allow for run-time system adaptivity. We implement the approaches on a Network-on-Chip multiprocessor platform prototyped on an FPGA. Their comparison in terms of the introduced overhead is presented on two case studies with different communication characteristics. We found out that the virtual connector mechanism outperforms other approaches in the communication-intensive application. In the other case study, which has a higher computation/communication ratio, the middleware approaches show similar performance.},
