Abstract
A syndrome processing unit for a multibyte error correcting system is disclosed in which logical circuitry for performing product operation on selected pairs of 8-bit syndrome bytes and exclusive-OR operations on selected results of the product operations are selectively combined to define usable cofactors that correspond to coefficients of an error locator polynomial corresponding to a selected codeword if the codeword contains less than the maximum number of errors for which the system has been designed.
