The "Turbo" codes are achievable in silicon with moderate effort.

And the payment of a suitable fee to the folks who OWN the turbo codes

Note also that turbo and LDPC are really suited to longer block lengths
(1000 bits and bigger). For small block lengths, codes like Hamming
might be better.

Reed-Solomon combined with Viterbi decoders of convolutional codes are
also popular.

Note that in deep space, at a bit rate of 8 bps, you might not want to
use a code with a 1000 bit codeblock..
