A deadlock-free routing algorithm requiring no virtual channel on 3D-NoCs with partial vertical connections

摘要

Elevator-first routing algorithm has been introduced for partially connected 3D network-on-chips, as a low-cost, distributed and deadlock-free routing algorithm using two virtual channels. This paper proposes Redelf, a modification of the elevator-first routing algorithm on a 3D mesh topology. The proposed algorithm requires no virtual channel to ensure deadlock-freedom.
