| Abstract | A generic analytical performance model of single-channel wormhole routers is presented using the M/D/1/B queuing theory. Compared with previous work, the flow-control feedback mechanism is studied in detail, and a computing method bases on Markov chain for the flow-control feedback probability is proposed. Compared with BookSim, a well-known cycle-accurate Network-on-Chip (NoC) simulator, this model presents accurate results on key metrics: the average relative error of flow-control feedback probability is about 7.87%. In addition, based on the model of single-channel routers, the asymmetric multi-channel and symmetric multi-channel structured routers are both modeled respectively. |
