Figure 1 Application Overview

Note: The CPS-10Q provides direct support for backplane connections using the serial RapidIO standard. The addition of an appropriate bridge (e.g.,

CPRI

 sRIO) allows for further backplane flexibility, accommodating designs based on a wide range of standards such as CPRI, OBSAI, GbE or

PCIe.

In a macro wireless station, a switch-based raw data combination and distribution architecture is widely adopted. Switch based architecture provides

high flexibility and high resource efficiency. The raw data from the Radio Unit is distributed to one or more processing cards by unicast or multicast.

Aggregating raw data from processing cards to a buffer-less chain can be done by a fast non-blocking switch.
