2. USER APPLICATIONS
The SpW-10X SpaceWire router device may be used in several different ways as described in the
following sub-sections.
Note: SpW-10X is pronounced “SpaceWire Ten X”. This name derives from the abbreviation for
SpaceWire (SpW), the fact that the router has eight SpaceWire ports and two external ports giving ten
ports in total, and the used of “X” to represent a cross-bar switch.
2.1 STAND-ALONE ROUTER
The SpaceWire Router may be used as a stand-alone router with up to eight SpaceWire links
connected to it. Configuration of the routing tables etc. may be done by sending SpaceWire packets
containing configuration commands to the router.

Figure 2-1 Stand-Alone Router
In Figure 2-1 an example of use of the SpW-10X device as a stand-alone router is illustrated. There
are four instruments connected to the SpW-10X device along with a memory unit and processor. The
processor can communicate with all the instruments and memory unit to control them and is also able
to configure the SpW-10X device. The instruments can send data to the memory unit for storage or to
the processor for immediate processing. The processor can also read data from the memory for later
processing, writing the processed data back into memory. A pair of SpW-10X devices can be used to
provide a redundant configuration.

2.2 NODE INTERFACE
The SpaceWire Router has two external ports which enable the device to be used as a node interface.
The equipment to be connected to the SpaceWire network is attached to one or both external ports.
One or more SpaceWire ports are used to provide the connection into the SpaceWire network.
Unused SpaceWire ports may be disabled and their outputs deactivated to save power. In this
arrangement configuration of the routing tables and other parameters may be done by sending
configuration packets from the local host via an external port or from a remote network manager via a
SpaceWire port.

Figure 2-2 Node Interface
In Figure 2-2 a SpW-10X router is used as an interface to a user FPGA or processor, which may be
part of a SpaceWire enabled instrument, control processor or other sub-system. The interface to the
user FPGA or processor is via the external FIFO ports of the SpW-10X router. Only three SpaceWire
links are needed for this SpaceWire node so the other five links are disabled to save power.
2.3 EMBEDDED ROUTER
The SpaceWire Router device can also be used to provide a node with an embedded router. In this
case the external ports are used to provide the local connections to the node and the SpaceWire ports
are used to make connections to other ports in the network. The difference between this configuration
and that of section 2.2 is just a conceptual one with the Node interface configuration normally using
fewer SpaceWire ports than the Embedded Router configuration.

In Figure 2-3 a SpaceWire system similar to that shown in Figure 2-1 is shown with the SpW-10X
router embedded in a SpaceWire node along with a processor. The processor interfaces can interface
to the SpW-10X router using the external FIFO ports saving some SpaceWire ports for connecting to
additional instruments. For redundancy a pair of the SpaceWire nodes with embedded routers may be
used.
2.4 EXPANDING THE NUMBER OF ROUTER PORTS
If a routing switch with a larger number of SpaceWire (or external) ports is required then this can be
accomplished by joining together two or more routers using some of the SpaceWire links. For example
using two SpaceWire links to join together two router devices would create an effective router with
twelve SpaceWire ports and four external ports. Note, however, that an extra path addressing byte is
needed to route packets between the two routers and that there is additional routing delay.

3. FUNCTIONAL OVERVIEW
A SpaceWire routing switch comprises a number of SpaceWire ports and a routing matrix. The routing
matrix enables packets arriving at one SpaceWire port to be transferred to and sent out of another port
on the routing switch. A SpaceWire routing switch is thus able to connect together many SpaceWire
nodes, providing a means of routing packets between the nodes connected to it.
The SpW-10X SpaceWire router comprises the following functional logic blocks:
• Eight SpaceWire bi-directional serial ports.
• Two external parallel input/output ports each comprising an input FIFO and an output FIFO.
• A crossbar switch connecting any input port to any output port.
• An internal configuration port accessible via the crossbar switch from the external parallel
input/output port or the SpaceWire input/output ports.
• A routing table accessible via the configuration port which holds the logical address to output
port mapping.
• Control logic to control the operation of the switch, performing arbitration and group adaptive
routing.
• Control registers than can be written and read by the configuration port and which hold control
information e.g. link operating speed.
• An external time-code interface comprising tick_in, tick_out and current tick count value.
• Internal status/error registers accessible via the configuration port.
• Watchdog timers on all ports.
• Internal status/error registers accessible via the configuration port using the RMAP protocol
[2].
• External status/error signals.
A block diagram of the routing switch is given in Figure 3-1.

The following paragraphs define the SpaceWire router functional logic blocks in more detail.
3.1 SPACEWIRE PORTS
The SpaceWire router has eight bi-directional SpaceWire links each conformant with the SpaceWire
standard. Each SpaceWire link is controlled by an associated link register and routing control logic.
Network level error recovery is performed when an error is detected on the SpaceWire link as defined
in the SpaceWire standard. Packets received on SpaceWire links are routed by the routing control
logic to the configuration port, other SpaceWire link ports or the external FIFO ports. Packets with
invalid addresses are discarded by the SpaceWire router dependent on the packet address. The
SpaceWire link status is recorded in the associated link register and error status is held by the router
until cleared by a configuration command.
3.2 EXTERNAL PORTS
The SpaceWire router has two bi-directional parallel FIFO interfaces that can be used to connect the
router to an external host system. The external port FIFO is two data characters deep. Each FIFO is
Preliminary

written to or read from synchronously with the 30MHz system clock. An eight-bit data interface and an
extra control bit for end of packet markers are provided by each external port FIFO. Packets received
by the external port are routed by the routing control logic to the configuration port, SpaceWire link
ports or the other external port dependent on the packet address. Packets with invalid addresses are
discarded by the SpaceWire router.

3.3 CONFIGURATION PORT
The SpaceWire router has one configuration port which performs read and write operations to internal
router registers. Packets are routed to the configuration port when a packet with a leading address
byte of zero is received. The Remote Memory Access Protocol (RMAP) [AD2] to access the
configuration port. A detailed description of the RMAP command packet format is provided in section
7.6. If an invalid command packet is received then the error is flagged to an associated status register
and the packet is discarded. The internal router registers are described in section 9.
3.4 ROUTING TABLE
The SpaceWire router routing table is set by the router command packets to assign logical addresses
to physical destination ports on the router. A group of destination ports can be set, in each routing
table location, to enable group adaptive routing. In group adaptive routing a packet can be routed to
its destination through one of a set of output ports dependent on which ports in the set are free to use.
When a packet is received with a logical address the routing table is checked by the routing control
logic and the packet is routed to the destination port when the port is ready.
Routing table locations are set to invalid at power on or at reset. An invalid routing address will cause
the packet to be spilled by the control logic. The routing table logical addresses can also be set to
support high priority and header deletion. High priority packets are routed before low priority packets
and header deletion of logical addresses can be used to support regional logical addressing (see
AD1).
3.5 ROUTING CONTROL LOGIC AND CROSSBAR
The routing control logic is responsible for arbitration of output ports, group adaptive routing and the
crossbar switching. Arbitration is performed when two or more source ports are requesting to use the
same destination port. A priority based arbitration scheme with two priority levels, high and low, is
used where high priority packets are routed before low priority packets. Fair arbitration is performed
on packets which have the same priority levels to ensure each packet gets equal access to the output
port.
Group adaptive routing control selects one of a number of output ports for sending out the source
packet.
Preliminary

SpW-10X
The crossbar switch connects an input port to an output port allowing data to flow from the input port
to the output port. Several input ports may be connected simultaneously to several output ports all
passing data. Two or more input ports may not be connected to a single output port. The crossbar
switch is a “non-blocking” type because the connection of one input port to an output port does not
prevent another input port being connected to another output port at the same time. It is possible for
all eight input ports to be each connected to an output port so that all input ports and output ports are
being used.

3.6 TIME-CODE PROCESSING
An internal time-code register is used in the router to allow the router to be a time-code master or a
time-code slave.
In master mode the time-code interface is used to provide a tick-in to the SpaceWire routing causing
time-codes to be propagated through the network. Two modes of time master operation are
supported, an automatic mode where a time-code is propagated on each external tick-in and a normal
mode where the time-code is propagated dependent on the external time-in signal.
In time-code slave mode a valid received time-code, one plus the value of the router time-code
register, causes a tick-out to be sent to the SpaceWire links and the external time-code interface. The
time-code is propagated to all time-code ports except the port on which the time-code was received. If
the time-code received is not one plus the value of the time-code register then the time-code register
is updated but the tick-out is not performed. In this way circular network paths do not cause a
constant stream of time-codes to be sent in a loop.
3.7 CONTROL/STATUS REGISTERS
The control and status registers in the SpaceWire router provide the means to control the operation of
the router, set the router configuration and parameters or monitor the status of the device. The
registers are accessed using RMAP [AD2] command packets received by the configuration port.
