4.4. Transport Layer

The Transport layer is a required module of the RapidIO II IP core. It is intended for use in an endpoint processing element and must be used with at least one Logical layer module or the Avalon-ST pass-through interface.
You can optionally turn on the following two parameters:
  • Enable Avalon-ST pass-through interface — If you turn on this parameter, the Transport layer routes all unrecognized packets to the Avalon-ST pass-through interface.
  • Disable destination ID checking by default—If you turn on this parameter, request packets are considered recognized even if the destination ID does not match the value programmed in the Base Device ID CSR—Offset: 0x60. This feature enables the RapidIO II IP core to process multi-cast transactions correctly.
The Transport layer module is divided into receiver and transmitter submodules.
