Performance Impact of Task-to-Task Communication Protocol in Network-on-Chip

Network-on-chip (NoC) is a strong candidate for scalable interconnect design of multi-processor system-on-chip (MPSoC). Software tasks of MPSoC require a certain protocol to communicate with each other. In NoC such a communication protocol should be handled at network interface and/or processor element level and it is expected that different protocols show their trade-offs. In consideration of the above, we employed two types of basic protocol and investigated their performance impact. The contribution of this work is to quantitatively evaluate effectiveness of using separate communication protocols depending on the task structure.
