This article presents a new low-latency crossbar design that can be used to interface systems working at different frequencies. For the case of multiple input ports contending for the same output port, contemporary designs provide localized arbitration solutions. The arbitration circuitry itself is a major contributor to the area and latency of the crossbar. This hinders the scalability of contemporary designs. The authors present a crossbar that uses a distributed arbitration mechanism in the form of token rings. This implementation provides a highly scalable solution, in terms of both area and latency.
