Abstract
A technique to perform fast decoding of a Reed-Solomon code. A first multiplier unit multiplies a matrix Bwith a column vector v using common adders to produce a column vector v. The vector v represents one of an error locator polynomial, an error evaluator polynomial, and a derivative polynomial for a (n, k) Reed-Solomon code. The matrix Bis over GF() including first h columns of a matrix B. A second multiplier unit multiplies non-unity components of a column vector A with non-zero components of the column vector vcomponent-wise in GF(q) to produce a column vector v, q being equal to n+1. A third multiplier unit multiplies diagonal sub-matrices of a matrix C with corresponding components of the column vector vin GF() to produce a column vector v
