Hi Gautam, Regarding the deserializing, yes, you are right. You will be converting the output data from encoder into two parallel bits (if LLR = 2). The first output data from encoder will be at the LSB input to decoder and second output data from encoder will be at MSB input to decoder. Then continue to alternate for the subsequent encoder output data. You may try to generate the simulation example for encoder and decoder separately. Then perform some comparison on the data in and out to have further insight. Please let me know if there is any concern. Thank you. Best regards, Chee Pin

Hi CPChan

I was able to get the output from ldpc decoder as you said in previous replies.

But there are some questions and issues which i am not able to resolve.

Q1. Signal Line(decoder)named as "ldpc_decoder_in_ready" remains throughout HIGH during the procedure of feeding data to decoder. Does it mean there 's something wrong in my design? This doesn't happen with ldpc encoder. It goes low for sometime after feeding encoder data.

Issue: The output which i am getting from LDPC decoder doesn't come at uniform intervals, because of which there's a lead/lag in final output stream and i am not able to get seamless data stream(I am feeding video output from digital camera to LDPC encoder).

PS: Now i have company Email Id(gautamkashyap@deal.drdo.in) and i need help to upgrade it to Intel Premier support.

Thanks and regards
