A performance enhanced adaptive routing algorithm for 3D Network-on-Chips

As the technology of semiconductor continues to develop, hundreds of cores will be deployed on a signal die in the future Chip-Multiprocessors (CMPs) design. So Three-Dimensional Network-on-Chips (3D NoCs) has become an attractive solution which can provide high performance. The network performance depends critically on the performance of routing algorithm. This paper proposes a novel adaptive routing in 3D NoC which can solve congestion not only in the intra-layers but also in inter-layers. Simulation results show that our proposed method significantly achieves the performance improvement compared with other transitional routing algorithms.
