Abstract :
A bit-serial architecture for multi-Gbps LDPC decoding is demonstrated to alleviate the routing congestion which is the main limitation for LDPC decoders. We report on a 3.3-Gbps 0.13-μm CMOS prototype. It occupies 7.3-mm2 core area with 1416-mW maximum power consumption from a 1.2-V supply. We demonstrate how early termination and supply voltage scaling can improve the decoder energy efficiency. Finally, the same architecture is applied to a (2048, 1723) LDPC code compliant with the 10GBase-T standard.
