Abstract
Embodiments of decoders having early decoding termination detection are disclosed. The decoders can provide for flexible and scalable decoding and early termination detection, particularly when quasi-cyclic low-density parity-check code (QC-LDPC) decoding is used. In one embodiment, a decoder iteratively decodes a data unit using a decoding matrix comprising a plurality of layers. After at least one iteration of decoding the data unit, the decoder determines whether the decoded data unit from a completed iteration and one or more layers of the plurality of layers satisfy a parity check equation. In response to determining that the decoded data unit from the completed iteration and each layer of the plurality of layers satisfy the parity check equation, the decoder terminates decoding the data unit. Advantageously, the termination of decoding of the data unit can reduce a number of iterations performed to decode the data unit.
