The switch fabric is the key building block of every router, and various switch fabric architectures are used in the market products. The crossbar-based switch fabric architectures (both buffered and unbuffered) offer very high performances and are widely used for high-performance routers. However their cost grows quadratically with the input/output port count, since they require internal crosspoints (and buffers) for every input/output port pair. Recently, a functional-level design of two novel Network-on-Chip based switch fabric architectures was proposed, Unidirectional NoC (UDN) and Multidirectional NoC (MDN), as a replacement of the buffered crossbar switch fabric architecture. In this thesis, we propose the hardware design and implementation of the aforementioned architectures for the FPGA platform. We further improve the routing and scheduling algorithms of these architectures for feasible hardware design. The synthesis and simulations are carried out over a wide range of switch sizes and traffic scenarios. The simulation results are also validated on the FPGA platform, by generating pseudo-random destination addresses for the packets on LFSR based test modules. The results show that UDN outperforms MDN in terms of throughput, whereas MDN offers greater performance-cost ratio. Both architectures offer scalability, flexibility and high performance, confirming the ideas in the original proposal.
