Figure 2-4 shows a pair of SpW-10X routers connected together using the external FIFO ports to
provide a 16 port router. A small amount of external logic is required to connect the external FIFO
ports in this way. Note that the bandwidth between the two SpW-10X devices is limited by the two
external FIFO ports used to interconnect them. Each FIFO port can handle one SpaceWire packet at a
time in each direction.
