Abstract:
1. Circuitry for generating a first number of Reed-Solomon check symbols from a second number of input data symbols, said circuitry comprising: storage for storing a plurality of generator coefficients, said plurality of generator coefficients being grouped into generator vectors equal in number to said first number, each of said generator vectors having values equal in number to said second number; a plurality of multipliers, each of said multipliers having a data symbol input, and a coefficient input coupled to said storage, and having an output resulting from multiplying said data symbol input by said coefficient input; and accumulator circuitry that accumulates outputs of said multipliers to generate said check symbols; wherein: respective ones of said input data symbols are input in parallel to respective ones of said data symbol inputs of said plurality of multipliers.
