Abstract
In recent years, the idea of wireless three-dimensional network-on-chips (3D NoCs) was promoted in order to design many-core chips with greater performance and lower energy consumption. This technology is the combination of different dies that are stacked on each other. Therefore, it is necessary to propose a suitable routing mechanism for irregular wireless 3D NoCs that can support the agnostic topologies. In this paper, we propose a deadlock-free routing algorithm for wireless 3D NoCs, called Floyd-base Inter-chip Traffic distribution (FIT), which is based on Floyd routing algorithm. In FIT algorithm, the number of hops is reduced compared to the already established deterministic algorithms; moreover, the traffic distribution is improved. Evaluation results show that our proposed routing algorithm significantly improves the performance and throughput by reducing the energy consumption, the average hop count and the communication latency.
