The alternate direction method of multipliers is a recent linear programming error correcting approach which improves the decoding performance of LDPC codes compared with the best BP decoding techniques. In this letter, an efficient implementation of the ADMM LP decoding algorithm on a multicore architecture is presented. Its throughput performance level is about one order of magnitude higher than related works on the same multicore target. The proposed decoder's throughput reaches up to 100 Mb/s which makes it viable for real time applications with tough error correction requirements.
