meaning of xnor

Name: Anonymous 2012-05-17 14:42

xor means exclusive or, ie a OR b, excluding the case when both are true. but what about xnor, what is the meaning of the word exclusive here? why exclusive nor, instead of not- exclusive or nxor?

Name: VIPPER 2012-05-17 15:12

Because its shorter.

Some use the term "equivalence" to describe "xnor".

  XNOR Truth Table
  ----------------
  Input      Output
A    B
0    0    1
0    1    0
1    0    0
1    1    1

So, XNOR is ==. Why the hell do you need XNOR?

Think of it as "Not XOR". So if XOR would return true, XNOR returns false and vice versa.

i know xnor is "not xor", but the name "exclusive" makes sense for xor.  but "exclusive nor" doesnt seem to make any sense to me.

but why "exclusive not or" ?

well, it is actually not exclusive or.

Name: Anonymous 2012-05-18 1:33

or is technically and/or.
nor is technically not and/or.
xor is a more "exclusive" or.
xnor is a more "exclusive" nor.

ah, more "exclusive". so or/nor are for dumb goyim and xor/xnor are for jews, right?

How does one make a CMP instruction with just one gate? I'd like to know because I'm currently making a processor and am pretty sure this requires a tree-structured reduction array

With 2 input pins and 1 output pin you construct 16 different types of gates. Using just three of these gates, AND, OR and XOR, one can construct the 13 others. Your XNOR is one of these 13, and just a convenience. However may be critical to implement it in hardware or CPU, if your application relies heavily on it.

Protip: In C, using the operator ?: and !, you can easily construct these 16 different operators.
AND x?y:0
OR x?1:y
XOR x?!y:y
XNOR x?y:!y     but NXOR would be a better name for this.

but nor is only true when both are zero, so how can xnor be more exclusive?

Name: Anonymous 2012-05-19 0:47

Because when we're talking about NOT exclusive applies to 0's and not 1's

A nobleman appears on his steed, watching over his peons. He notices a man in ragged clothing, shoveling manure around his crude hut. The nobleman calls out, "You there, genius!" The man turns to face his master. "Yes me lord?"

what the fuck man, xnor is the same as nor?
nxor doesn't exist.
i think xnor should be called nxor, and the name "exclusive nor" doesn't make any sense.

nxor doesn't exist.
That's the point. "exclusive nor" is tautological because nor only has one positive out of the four possibilities. An exclusive nor would equal the exact same thing as nor.
