Abstract
Techniques for reducing the latency for decoding product codewords with minimal hardware architecture changes are described. In an example, multiple decoding procedures are available a system. The system maintains decoding states. Each decoding state corresponds to a constituent codeword of a product codeword and to a decoding procedure. For instance, a BCH decoding state indicates whether the decoding of the respective BCH constituent codeword has previously failed. The decoding of the product codeword depends on the various decoding state. For instance, in a BCH decoding iteration, if a BCH decoding state of a constitutent codeword is set to “failed,” the BCH decoding of that codeword is skipped.
