What is the IP core?

Question

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:

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?  http://www.altera.com/products/ip/dsp/error_detection_correction/m-alt-rs-encoder-decoder-ii.html

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