Seems
excessive... I seem to recall you need log2(n) - 1 bits, which
would be 3 bits (32-bit ECC needs 4 bits).
Doesn;t that assume the 'extra'
bits are known to be correct. Those
can be in error too (even if the'real' data bits are correct),
No, it doesn't. See Wikipedia's Hamming code page (asking for SECDED
redirects to it) for a brief treatment of the subject, or any of many
more detailed treatments of coding theory for more.
