Native Ethernet RoE mapper/demapper

General Description

Comcores RoE mapper/de-mapper IP core for native Ethernet is a silicon agnostic implementation of the native Ethernet mapping method described in the IEEE 1914.3 standard. The IP-core interface to data converters through RAM blocks and can as such be used for multiple different converter interfaces. The data are mapped into one or several 10G Ethernet data streams and vice versa and has been tested with live transfer of I/Q data in frequency domain interfacing to L1 offload engine. The IP-core allows for synchronization from various sources.
