Circuitry for, in p parallel streams, searching a codeword having n symbols for roots of a cyclic code polynomial having a number of terms includes a plurality of multipliers, a source of constants derived from roots of the polynomial, and at least one counter that supplies an index. For each received symbol of the codeword, the multipliers multiply respective terms of the polynomial for a previous received symbol by constants from the source of constants, the counter advances to select respective products of the constants and the respective terms for the previous received symbol. |
