Figure 2-4 Expanding the number of SpaceWire Ports (1)

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.
