A (72, 64) Sec-Ded With 4-Bit Package Error Detection

      Disclosed is a (72, 64) SEC-DED code with quasi-cyclic
property, minimum number of XORs in check bit generation, and 4-bit
package error detection capability.

      The disclosed code is defined by the following parity check
matrix:

      A grouping scheme for the bit positions to detect all single
4-bit package error detection is shown as follows: (32,37,22,C3)
(49,12,34,43)  ( 7,23,39,55) (40,45,30,C4)  (57,21,42,51)
(15,31,47,63) (48,53,38,C5)  ( 1,28,50,59) (56,61,46,C6)  ( 9,36,58,
3) ( 0, 5,54,C7)  (17,44, 2,11) ( 8,13,62,C0)  (25,52,10,19) (16,21,
6,C1)  (33,60,18,27) (24,29,14,C2)  (41, 5,26,35)
