1. A Reed-Solomon decoder capable of decoding an n-symbol decision-codeword to produce a k-symbol dataword where the number of symbol errors in the decision-codeword is greater than t=(n−k)/2, the decoder comprising:
a syndrome computation circuit that performs a recursive computation to generate a plurality of values eαi·j, said syndrome computation circuit adding said plurality of values to existing syndromes to produce a plurality of modified syndromes,
where j is a symbol position, e is an error value corresponding to the symbol position, and i is a non-negative integer.
