H-matrix for error correcting circuitry

摘要

A matrix H for encoding data words is defined for wide word ECC with uniform density and a reduced number of components. The H-matrix is incorporated in an encode unit operable to Hamming encode a data word with a 10x528 matrix generated in groups of four columns wherein; a first column is a complement of a second column; the value of the second column ranges from 9 to 271 in increments of two; a third column is a complement of a fourth column; and the value of the fourth column is the same as the value of the second column less one; and wherein a 528-bit bottom row is added to the 10x528 matrix comprising alternating zeroes and ones starting with a zero creating an 11x528 matrix.
