Note: The CPS-16 provides direct support for backplane connections using the serial RapidIO standard. The addition of an appropriate bridge (e.g., CPRI
allows for further backplane flexibility, accommodating designs based on a wide range of standards such as CPRI, OBSAI, GbE or PCIe.
The sRIO Switch supports a peak throughput of 40 Gbps which is the line rate
for 16 ports in 1x configuration, each at 2.5 Gbps (3.125 Gbps minus the sRIO-
defined 8b10b encoding), and switches dynamically in accordance with the
packet headers and priorities.
Enhanced features are provided for support of system debug. These features
which are optional for the user consist of two major functions:

Three major options exist within this category:
a. Packet Trace: The Packet Trace feature provides at-speed checking of
the first 160 bits (header plus a portion of any payload) of every incom-
ing packet against user-defined comparison register values. The trace
feature is available on all serial RapidIO ports, each acting indepen-
dently from one another. If the trace feature is enabled for a given port,
every incoming packet is checked for a match against up to 4 compari-
son registers. In the event of a match, either of two possible user
defined actions may take place:
i) not only does the packet route normally through the switch to its
appropriate destination port, but this same packet is replicated and
sent to a “trace port”. The trace port itself may be any of the standard
a. Multicast: If a Multicast ID is received, the CPS-16 performs a
b. Unicast: All other operations are performed as specified in sRIO
c. Maintenance packets: As specified by sRIO

If there is no match, the packets route normally through the switch with
no action taken.
The Packet Trace feature can be used during system bring-up and
prototyping to identify particular packet types of interest to the user. It
might be used in security applications, where packets must be checked
for either correct or incorrect tags in either of the header or payload.
Identified (match) packets are then routed to the trace port for receipt by
a host processor, which can perform an intervention at the software
level.

are immediately looped back at the physical layer to the transmitter -
bypassing the higher logical or transport layers.
