Fec and IP

KMX 100G MAC and PCS core, which consists of media access control (MAC) module, physical coding sublayer (PCS) module and physical medium attachment (PMA) module, is compliant with the IEEE 802.3ba-2010 standard.
The core implements RS FEC as defined in IEEE 802.3bj Clause 91 with independent bit error detection and bit error correction.

KMX 40G MAC and PCS core, which including media access control (MAC) module, physical coding sublayer (PCS) module and physical medium attachment (PMA) module, is compliant with the IEEE 802.3ba-2010 standard.
The core supports RS FEC as defined in Clause 74 IEEE 802.3 with independent error bit detection and error bit correction.

UALink, the standard for AI accelerator interconnects, facilitates this scalability by providing low-latency, high-bandwidth communication.
As a member of the UALink Consortium, Cadence offers verified UALink IP subsystems, including controllers and silicon-proven PHYs, optimized for robust performance in both short and long-reach applications and delivering industry-leading power, performance, and area (PPA).

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.

The CMS0044 J.83abc/DVB-C Cable FEC Encoder combines all of the channel coding and Forward Error Correction functions specified by DVB-C and by J83 Annexes A B and C.
It is designed to interface to external modulators or advanced upconverting DACs such as the Analog Devices AD9789.

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.
