CPRI over Ethernet

General Description

Comcores offes a structure agnostic and a Structure Aware Mapper/Demapper/de-mapper IP core for transferring data over Ethernet. The implementations adhere to the IEEE 1914.3 standard and enable deterministic latencies and control of timing through build in synchronization ports. The IP-cores take multiple streams of CPRI data and map these into one or several 10G Ethernet data streams and vice versa. Using the Structure Aware Mapper/Demapper saves overhead and allows for a much higher degree of control with the data flows.

To ensure easy integration build-in test capabilities is provided in the core.
