What is the IP core?

[Altera_Forum]

Hello. 

 I would like to know, what is the IP core that is named “10G GFEC RS(255, 239) MegaCore”.   I have not find this core by the search. I’ve found only such IP core description by Google and Altera search: http://www.altera.com/literature/po/ss-rsgfec.pdf (http://www.altera.com/literature/po/ss-rsgfec.pdf)   Are they the same? If yes (or no), how can I get the detailed description of “10G GFEC RS(255, 239) MegaCore”?   Thank you in advance for answers.

I think its a FEC(forward error correction) core with ReedSolomon Decoder. This core is integreted with 10G ethernet (PCS)

Thank you for answer. 

 Of course, this is FEC, RS(255, 239). I don't sure that it is integrated with 10G Ethernet, because there are several 10G interfaces with and without FEC support...   So I would like to receive exact description of the core.

is it the Reed Solomon II core?

Reed Solomon II is a configurable core. 

 RS(255, 239) means that it is fixed core for encoding/decoding Reed Solomon (255, 239) codes.
