Off topic?

[83R23RK R0807]

Just thought it would be humorous to point out nearly EVERY thread started in any forum section gets hijacked/off topic by the 5th post. Im assuming some smarty pants in here will go to great links to get this thread off topic by the second or third post, just to be funny..... so have at it.

Yeah, sorry about that. Im probably the most guilty.

To make an excuse (sorry, im married so im programmed to make excuses), for a long time these forums were practically dead. In fact, that whole time you were gone, Robo, the forums kinda went into hibernation. I suppose it had to do with the empty BF1942 server and thus people were beginning to lose interest. Now, with BF2 and our new BF2 server, there is 10 times more activity here, even though most of it is EA bashing . Anyway, my excuse is that I used to take threads off-topic just to get some activity and force a response. Otherwise, I was afraid people would completely stop visiting.

Its a bad habit that I know is breaking the rules of forum etiquette. However, I don't know if I can stop! I need help. . . or a life ;D.

It's funny how, in a binary number system, you can just add one to the One's Complement of a negative [signed] binary number (this would be the Two's Complement) and use it with an Adder to achieve subtraction! Amazing!

Now if I could only add a one to every smacktard on the server, we'd have a lot more positi--REPUBLICANS!!!one!!!1! They're everywhere! R0b3r7Z \/\/iLl $3|\|d u$ b4(|< 2 t3h $70|\|3 4g3!

But back to the topic: Adders.

Very poisonous!

But back to the topic before that!: Full Adders

Very poisonous and have just eaten!

Okay, but seriously:

Therefore, our sum form is for Sum(Inp1, Inp2, Carry) is SUMMATION(1,2,4,7) and for Overflow(Inp1, Inp2, Carry) is SUMMATION(3,5,6,7).

Reducing that using a Karnaugh Map should give us canonical sum form, eh?

Let's call Inp1 "x", Inp2 "y", and Carry "z":

Sum

\ yz
..\.....00...01...11...10.
x...0|.....|..1.|.....|..1.|
....1|..1..|.....|..1.|.....|

Sum: x'y'z + xy'z + xy'z' + xyz
(can't be reduced?)

Overflow

\ yz
..\.....00...01...11...10.
x...0|.....|.....|.....|..1..|
....1|......|.1..|.1..|..1..|

Overflow: xz + yz'

Alas, I've screwed up somewhere in there and thus the adder I programmed in lab won't work

Oh well, it's not due for another three weeks.
Anyhow, I've run out of time to make the circuit diagrams. Oh, darn.

Hey ryland:

010110010110111101110101001000000110000101110010011001010010000001100001001000000110111001100101011100100110010000100001

figure out what that means! (its my native tongue - real binary)

Given that string of binary, are we talking about signed/unsigned/ASCII/BCD/IEEE representation?



It's ASCII:

Gah, I *am* a nerd! j00 r0xx0rZ!

Let's try:

Hey! No foreign languages are allowed! hehe, you geeks.

i just boiled my brain trying to understand ryland's program.
but i do understand this.

Hey, hey -- that's the **AMERICAN** Standard Code for Information Interchange. It's not like we're using Unicode.... uuunleeesss....

HI BK!!!!!!!!11

Ryland: Looks greek to me!

[[Ryland]69ee™]

Hey BK, long time no see! (like, since a billion posts ago methinks).

Those are encoded via UNICODE.

Likewise, the top is Greek, whereas the bottom is Cryllic.

You know, we could get shut down for that Ryland! Where not on the new forum yet .
