Bottom Line: During the routing period, other nondestination nodes can be used as middle stages to transfer data packets to complete the routing mission.Therefore, this topology has the characteristic of multistage.Simulation analyses show that BFC inherits the rich path diversity of Clos network, and it has a better performance than butterfly network in throughput and delay in a quite congested traffic pattern.

ABSTRACT
This paper studied the topology of NoC (Network-on-Chip). By combining the characteristics of the Clos network and butterfly network, a new topology named BFC (Butterfly Clos-network) network was proposed. This topology integrates several modules, which belongs to the same layer but different dimensions, into a new module. In the BFC network, a bidirectional link is used to complete information exchange, instead of information exchange between different layers in the original network. During the routing period, other nondestination nodes can be used as middle stages to transfer data packets to complete the routing mission. Therefore, this topology has the characteristic of multistage. Simulation analyses show that BFC inherits the rich path diversity of Clos network, and it has a better performance than butterfly network in throughput and delay in a quite congested traffic pattern.

Mentions: Clos network [20–22] was first proposed by Charles Clos in 1953. Clos network is the most commonly used three Clos network C(m, n, r) shown in Figure 1, where m is the number of middle-class switching units; n is the input ports of the input stage switch module, which is the output ports of output level switching units; r is the number of input stage switching unit, which is the number of output stage switching units. Each switch module is a crossbar structure in accordance with crossbar model to work.
