Third party LDPC ip Core

Hello

Any body using LDPC ip core on Altera platform which is optimum in terms of performance, resource and Latency.

Altera own ip core having lot of limitation with compatible Encoder and Decoder-

1. Wimedia Encoder and Decoder having limited block size (Approx 1200 bit) while

2 NASA std Encoder and Decoder having limited code rate of 7/8 or 8/9.

Kindly suggests us another third party LDPC ip core which has block size from 1K to approx 8K and code rates of 1/2 to 8/9, Data with optimum in terms of performance, resource, Latency & implementation

Thanks
