Stochastic communication in application specific networks-on-chip

Networks-on-chip (NoC) is a new approach to System-on-chip (SoC) design. NoC consists of different Intellectual Property (IP) cores. The NoC solution brings a networking method to on-chip communication and claims roughly a threefold increase in performance over conventional bus systems. In this paper we proposed a new method for stochastic communication between the different IP cores. These IP cores are connected with different routers or switches and are treated as different compartments on the single chip. The spread of information among these IP cores can be represent using a closed donor control based compartmental model, which can be converted into a stochastic model. The stochastic model is more realistic and enables us to compute the transition probability from one IP to other IP core as well as latency.
