ABSTRACT:
Provided are an encoder and a syndrome computer for cyclic codes which process M codeword symbols per cycle where M is greater than or equal to one, whereby the encoder and syndrome computer optionally further provide the configurability of a different M value for each cycle and/or the configurability of a different cyclic code for each codeword. Further provided is a hybrid device which provides the configurability of two modes of operation, whereby in one mode, the hybrid device functions as the encoder as provided above and, in the other mode, the hybrid device functions as the syndrome computer as provided above, with the majority of the components of the hybrid device being shared between the encoding function and the syndrome computing function.
