| الوصف: | We focus on a hardware implementation of the concatenated forward error-correction (FEC) decoder defined in 400ZR implementation agreement to provide a throughput of 400 Gbps over fiber-optical communication links. We propose a soft-input hard-output low-complexity decoding algorithm for the inner Hamming code. We demonstrate that the algorithm leads to an efficient hardware design with low silicon area and power dissipation. We then propose a hardware implementation architecture of the outer staircase decoder. It features a highly optimized low-power implementation of Bose-Chaudhuri-Hocquenghem (BCH) component decoders and the staircase decoder memory that can be efficiently accessed by either vertical or horizontal component decoders. Finally, we analyze the hardware implementation of the entire 400ZR decoder and investigate the trade-off in terms of power, area, and speed, that results from the inner/outer decoder concatenation and is dictated by the bit-error rate at the output of the inner decoder. |
