Abstract: Nowadays, three-dimensional network-on-chips (3D-NoCs) have been introduced as the most efficient communication architectures. In these architectures, it is likely to encounter some faults. Therefore, an important goal in designing such architectures is to make them more tolerable against faults. In this paper, an adaptive, distributed and fault-tolerant routing algorithm called ADFT is proposed for 3D mesh-based NoC that is able to tolerate permanent faults and does not require any additional circuit for fault-tolerant. In order to evaluate the performance of the ADFT, we compared it with LOFT in terms of latency and throughput. Simulation results show improvement of the proposed method.

Keywords: three-dimensional network-on-chip; 3D-NoC; routing algorithm; permanent fault; fault-tolerant.
