Summary:

An information router in a communication network should deliver data packages from one node to other node. For executing this delivery task efficiently, the router should choose the best path between the nodes. The best path can be fixed or can change every time a new data package must be delivered. Router circuits can be used on Network–on-chip (NoCs) to keep track of communication paths inside the chip. This solution can solve the performance requirements of the modern single chip with billion transistors processors. The NoC approach provides a highly structured and scalable solution to tackle the communication problems in those complex systems, due to the high bandwidth, relatively low power consumption and low latency exhibited by NoCs in comparison to more conservative designs. Nanoelectronic devices, such as Single Electron Transistors (SET), are able to confine electrons in nanometric dimensions making it possible to observe quantization of both their charge and their energy. So SET’s are quantum mechanical devices and their features should allow building integrated circuits with a number of devices orders of magnitude greater than the indicated by the roadmap still respecting area and power consumption restrictions. In this way, Tera Scale Integrated (TSI) systems can be feasible in the future. In this work a completely SET based nanoelectronic circuit for an information router for NoC applications will be proposed and simulated. Furthermore, the performance will also be analyzed and compared to others implementations. It will be shown that the SET-based router has a promising performance considering parameters such as speed, power consumption and area.
