A circuit-switched network architecture for network-on-chip

This paper presents a circuit-switched network architecture for network-on-chip. It uses time-division-multiplexing (TDM) scheme to realize the circuits. The global routing (slot assignment) is done centrally, while the slot mapping is done locally by the switches. The switches support multicast operation, which enables multicast traffic. Furthermore, the delay in the network is predictable before a circuit is established and in-order data delivery is guaranteed.
