DSP & Math IP

Small Size
Implements FEC Sublayer for 10GBASE-R (section 74 of the IEEE 802.3 standard)
10G/40G/100G Ethernet MAC-friendly interface
Practically self-contained: requires only memory for one 2112-bit block in the decoder.

This high performance core is a full featured Forward Error Correction encoder and decoder, specially designed for high speed optical networks or any other broadband applications.
It is fully compliant with the 2.5 Gbps GPON standard (G.984.3) and is available for FPGA or ASIC implementation.
The FEC algorithm is based on Reed-Solomon (255,239) code and consists of an encoder and decoder module.

The DVB-GSE encapsulator and decapsulator IP cores close the gap between network protocols like Ethernet and the physical layer of the DVB family of standards.
The DVB-GSE encapsulator performs the encapsulation of the network layer packets, also referred to as Protocol Data Units (PDUs), into one or more GSE packets, adding control information and performing integrity checks when necessary.

The CMS0077 Satellite FEC Decoder has been designed specifically to meet the requirements of the DVB-S2 and DVB-S2X advanced wide-band digital satellite standards.
The core provides all the necessary processing steps to convert a demodulated complex I/Q signal into a standard TS output stream.

OpenROADM oFEC (Open Forward Error Correction) is a core element of the OpenROADM initiative, providing a standardized, open-source FEC solution for high-speed coherent optical networks.
The oFEC IP cores deliver high coding gain through a fully parallel, pipelined decoder architecture with 3 soft-decision (SD) and 2 hard-decision (HD) decoding steps. It supports data rates from 200G to 800G, including Probabilistic Constellation Shaping (PCS) modes to enhance spectral efficiency, noise tolerance, and transmission reach.
