The XOR Gate

[Awtii69UPSB]

i have one of these in my irl house :)

[brtmn0]

i like the XOR gate with a t flipflop it is a good sestym together

[turtlegodkame]

I like that it's in the shape of an X too!

[TheDrPorkenheimer]

This is great for simple doors and other projects. Great tutorial!

[Teraku2]

By the way, what's your skin?

[Gigaspine7]

@Teraku2 Looks like Hobbes.

Wow, I wish I had seen this tiny one before I made a huge on for my secret door!

While really compact, it's suboptimal. A xor should take 2 tick ideally, and this is 3 ticks.

@cxgamer Space >> Time quite often in my opinion.

[cxgamer]

@sirdavva Most minecraft CPU's are very slow atm. Mainly due to them being suboptimal. I'd rather have something that's very big and fast than something spammed with repeaters and slow. But that's my opinion, and you have your opinion and that's fine ofc. :)

Currently making a Kogge-Stone Carry-Lookahead Adder, which is at least 3 times as big as a ripple carry, but 6 ticks faster.

[sirdavva]

@cxgamer Sounds cool!

[cxgamer]

@sirdavva Thanks. Also I made a T-flipflop (TFF) 2-wide tileable and theoreticly perfect. I made that into a counter that takes 5 ticks to output, capable of counting fast (like series minecarts passing by). If I were to make it much smaller, it'd be much slower, and incapable of fast counting. Just goes to say why compactness isn't what I want.

@cxgamer Why is that important in Minecraft?

[cxgamer]

@Minecraftaddict Well on small scale it doesn't really matter. But when adding this to a ripple carry, a 8 bit ripple carry will need 16 ticks, but if every xor would take a tick more, it's take 24 ticks, which is almost a second slower in ideal conditions.

I'm specialised in optimisation, I go through hell saving every last tick.

[TheJessassin]

@Minecraftaddict depending on what you are doing, it may be important... for example, in my situation it is important to make my ALU as fast as possible. the less ticks, the better

[MrAdnan252]

is this the start of your new series?

[Minecraftaddict]

@MrAdnan252 Just making content for my r/minecraftaddict subreddit.

[Werefreek]

is it possible to do one with more than 2 inputs?

[MrAdnan252]

@Werefreek yeah but that would be an adder and you'd need an extra xor

[cxgamer]

@MrAdnan252 I believe a full adder as you describe requires 2 half adders, which in term consist of a XOR and an AND. Though that's not what he asked.

[MrAdnan252]

@cxgamer i know that, but that's the only way to do an XOR with more than 2 inputs as far as i'm aware, having tested it several times.

[cxgamer]

@Werefreek A triple input xor is rarely used.

[WannaComment2]

@Werefreek Build two xor gates. Both of them with two switches each as input (That's your 4 inputs). Then use the outputs of these two xor gates as the input for a third one. The output of this third xor gate goes to the door. Pretty sure this should work.

[Minecraftaddict]

@WannaComment2 Exactly. See next video. ;)

[Minecraftaddict]

@Werefreek See the next video. ;)

[MrShaggyDuck]

Wow... Another Video? :)

[Minecraftaddict]

@MrShaggyDuck Ya, I know. It's been a while. Sorry.

[MrShaggyDuck]

@Minecraftaddict No I Mean Its Good That Theres Another Video! :) I Really Enjoy Them :)

[Zhylo]

@MrShaggyDuck. Why do you capitalize each word? That's not how English works.

[MrShaggyDuck]

@Zhylo Lol, Idk Really, Its Just A Habit :L

[MrShaggyDuck]

@Zhylo Im Half Spanish aswell, Well I Live In Spain :P So I Speak Spanglish Which InCludes Capitalizing Each Word
