Global routing for multicast-supporting TDM network-on-chip

Abstract

This work presents a circuit-switched network architecture for network-on-chip. It uses the time-division-multiplexing (TDM) scheme to realize the circuits. The global routing (slot assignment at each switch) 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.
