[Question] How to utilize multiple physical links in router in FlooNoC.

[tayyabshaikh]

1. Router in FlooNoC can have multiple physical ports. How can we utilize it to increase (say double) the Bi Section Bandwidth of the NoC?
2. These physicals links can be connected to routers, but how can we connect these multiple physical links to the Chimneys?

I hope my question is making sense.

I think increasing the number of ports in a router doesn't make too much sense to increase the bisection bandwidth. Because if you have for instance double the number of links form one router to another router, the routing algorithm also needs to be adaptive in some way, which is not the case at the moment.

However, the easiest way to increase the bandwidth is to just add multiple physical networks resp. more physical channels. For each of the channel you need to add a dedicated chimney, so you will also have multiple AXI ports per endpoint
