The Bridge (AXI 64bit -> AHB 32bit)

The NIC-400 is designed to be a multi-source, multi-destination configurable AXI interconnect.

But in its simplest form it is a single source to single destination component, not then requiring any address decoding and routing logic, and so is a configurable bridge.

So the bridge isn't included in the NIC-400 network, it IS the NIC-400 interconnect (in its simplest form).

You can also specify an AXI interconnect, with external interfaces that can be AXI3, AXI4, AHB-lite or APB protocol, and these "bridge" functions will then be implemented before or after the central AXI structure as part of the NIC-400 interconnect to give the required external interface protocols, data widths and clock domains.
