This paper presents a novel method to deal with deadlocking in multicast routing in mesh Network-on-Chip. The proposed design does not use the virtual channels used in the conventional designs, instead it provides a unique method to interleave data from different input ports. The method avoids deadlocking in tree-based multicasting by providing a flit-by-flit interleaving and at the same time reducing...
This paper presents the first synthesizable network-on-chip (NoC) based on a mesh topology, which supports adaptive and deadlock-free tree-based multicast routing without virtual channels. The deadlock-free routing algorithms for unicast and multicast packets are the same. Therefore, the routing function gate-level implementation is very efficient. Multicast packets are injected to the network by...
This paper presents a network-on-chip (NoC) with flexible infrastructure based on dynamic wormhole packet identity mapping management. The NoCs are developed based on VHDL-modular approach to support the design flexibility. The on-chip router switches packets using wormhole packet switching method with synchronous parallel pipeline technique. Contention-free routing algorithms and dynamic packet identity...
