Abstract

A mechanism for determining a number of errors in an error correction code codeword is presented. The mechanism obtains the degree of an error locator polynomial associated with syndromes generated for the codeword without determining coefficients of the error locator polynomial. The degree is identified as the number of errors. The degree is determined from the syndromes using a Euclidean process which determines the degree without finding the coefficients. Alternatively, the degree is determined by forming a trapezoid-shaped matrix from the syndrome values and finding the rank of that matrix.
