The decoder receives the channel information y and calculates messages stage by stage until a maximum number of iterations is reached or all the parity-check constraints are satisfied. In , it was observed that the number of iterations required to match the errorcorrection performance of SC decoding was large, negating the benefits of the increased parallelism. 3) . However, it was observed in  that the N/2 PEs were only used simultaneously once in the decoding, leading to low utilization of the hardware resources.
For applications like 10 GBASE-T Ethernet only fully parallel architectures can achieve the required throughput. 9 depicts the high-level structure of such a decoder. However in general it is not advisable to build this architecture as it has a serious drawback which is directly related with the two networks between VNs and CNs. Dependent on the code length and quantization, each of them comprises between several thousands and hundred thousands of wires which have to be routed according to the parity check matrix.
To connect multiple instances of a decoder, a distribution network and memories are required. Moreover a control unit to keep the blocks in order must be instantiated in the system. Summarized straightforward decoder duplication can increase the system throughput. However the latency issues caused by partially parallel architectures cannot be solved. Potential enhancements due to the increased parallelism are not explored and the system’s efficiency is slightly decreased due to the introduced overhead.
