Functional Description
A block diagram of one CSIX-to-PI40 Bridge channel is shown in Figure 2. Cframes received at the CSIX port are
checked by the CSIX Inbound Macro and loaded into the Inbound CSIX FIFO. The CSIX information is then passed
to the Ingress Fabric Interface (IFI) block that interprets the Cframe header, generates the appropriate PI40 header
and maps the Cframe into PI40 cell payload. The PI40 cells are then written to the ORSO82G5 embedded core,
which serializes and formats the SONET-based data frame structure and manages transmission on the SERDES
links.
PI40 cells received in the egress direction on SERDES links are extracted and deserialized by the ORSO82G5
embedded core and passed to the Egress Fabric Interface (EFI) block. The EFI extracts the Unicast and Multicast
ID Cframes from the PI40 cells and writes them into the Outbound CSIX Data FIFO. The EFI extracts backpressure
information from the PI40 cell headers and passes it to the Backpressure Processor (BPP). The BPP generates the
appropriate CSIX Flow Control Cframes that are written into the Outbound CSIX Control FIFO. Cframe transmis-
sion at the CSIX interface is managed by the CSIX Outbound Macro.
