Abstract: A method and device for energy-efficient decoders. The decoder device can include a plurality of decoder modules configured to process an input data signal having a plurality of forward error correction (FEC) codewords. This plurality of decoder modules can include at least a first decoder followed by a second decoder. The first decoder can be low-power to first eliminate most of the errors of the codewords and the second decoder can be high-performance to correct the remaining errors. Alternatively, the first decoder can be high-performance to correct the codewords until the low-power decoder can correct the remaining errors. A classifier module can be included to determine portions of the codewords to be directed to any one of the plurality of decoder modules. These implementations can be extended to use additional decoders with different decoding algorithms and optimized to maximize decoder performance given a maximum power constraint.
