Redstone Binary Addition - LRR #4

[@idkcba]

Even as a computer science student who has been working with logic gates and binary for 6 years now, this series is SO good. You're amazing at explaining things on such a fundamental level that people who have worked with it for years as well as people who have never worked with it can completely understand you. If you were my computer science teacher I bet the rest of the class, who never gave a crap, would still be able to understand and be intrigued. Keep up the good work, you deserve any and all support you get ❤❤ (P.s you also deserve 1m subs in my opinion 😄😄)

This series is amazing. I'm 40 and as a child I was brought up creating electronic devices like radios, amplifiers etc, and as an adult I'm a professional software developer, so this beds well with what I'm good at. I absolutely love what you're doing and your explanations are second to none. Keep up the great work!

Even though I know all these as I am a programmer, but still it feels worth it to watch all these videos with prior concentration, because I might end up learning something great and new. Another fun fact is, now I understand redstones stuffs better when I watch your videos! Keep up the good work!

One thing I would change about this episode is showing the logic gate diagram for the half adder and full adder.

[@Jmcgee1125]

Watching this after building a full 8-bit computer (custom ISA) just makes me realize how much of a miracle it is that any of it worked. My friend and I thought we were so smart reusing the RCA's XOR and AND gates for other parts of the ALU, alongside other "incredible" hacks, but all of that cascaded into a final safe clock speed of just under 11 seconds per cycle. But hey, the thing actually worked, which is still nuts to me.

[@mattheus1331]

Great content as always. What a time to be alive

[@BooliumNor]

I hope you’ll be covering division. I’ve already created a 10-bit calculator that can do addition, subtraction, and multiplication with any 3 digit base ten numbers. I’ve been struggling to find a way to do division. I know how to do it on paper in binary, but not in a circuit. (If you’d like to see my calculator, it’s on my channel, but it’s nothing compared to your Redstone projects.)

[@mattbatwings]

probably will not be covering multiplication, division, sqrt, as im decently happy with how they were explained the first LR series. check out those videos if you haven’t already

[@BooliumNor]

@@mattbatwings ok! Thank you!

[@bibi0x25]

@@mattbatwings How would you extend the clear signal while doing the multiplier so it stays synced? Also will you do fractions further in the series and if you do will it be the fixed point like in the sqrt tutorial or floating point (IEEE 754)?

Thanks for explaining the 5 bit CCA, the carry cancel is truly elegant

[@LightslicerGP]

I'm so glad this video includes both adding types, it's a lot less of a hassle than the last logical redstone series

[@itssomethin]

Ive watched this same video about 4 times already and im understanding a little bit You explain it way better than most people

[@matthewparker9276]

Fun fact, because the full adder takes in three bits as input and gives two bits as output, using one actually destroys information. This means it is an irreversible interaction, and it causes entropy to increase.

[@brainboy53]

I just built my first full adder and my heart was pounding when I went to go check to see if the results were correct

[@MahsonAmer]

Day 3 of my first time learning redstone, from this tutorial I learnt from the 4-bit RCA and managed to build an 8-bit one by myself, I tested it and it works flawlessly, I always see these redstone builds and say to myself that I would never achieve it, today I have great hope

[@MarcAntoine29_YT]

With your tutoriel my redstone passion has came back and now i Will try to make more redstone logical système thanks you again

[@hq4pr]

I can't belive because of your instructions, I managed to create my own design for an and gate and an Xor gate and made the same functioning half-adder that you did in the Half-Adder Derivation segment.

[@bgmarshall]

About a month ago I made a binary adder entirely on my own and it's really nice to see other ways it can be done.

[@KiwiRedstone]

Hi Matt, I have been following you since the middle of your previous logical redstone. I just wanna ask if you have any plan covering basics of desigining practical ALU / op code / instruction set / computer architecture in general in order to build an actual CPU in Minecraft?

[@laserpanda9553]

Realising the logic behind the carry cancel for the first time is incredibly clever

[@codewithzi-5817]

As an electronic circuit student, i want to say that we can use the full adder to do a subtraction by Xor all B input with carry in and pull it to HIGH value. Also, after i overview how redstone works, i think i can make a real life circuit to imitate the redstone function, but the main problem is piston cant break the redstone circuit 😂

[@Webzpsy]

This officially blew my mind and now I have a million idea's. Thankyou

[@blubsty]

It's crazy you know a lot of things on Redstone but you seem feel like not I totaly enjoyed

[@koyarnosredstone5783]

For those wondering, on 3 tick cca's, the comparator that calculates the carry, also does double duty as the last XOR. You can view this last XOR as 2 nimplies: (!S AND C) OR (S AND !C). The first Nimplies is covered by letting A XOR B disable the comparator that calculates Carry, and the second Nimplies is covered by letting A XNOR B disable the comparator that calculates !Carry. So where is !carry coming from without losing time? you swap the generate and cancel towers for this second comparator. There are some edge cases but thats the short explanation.

[@TechnoRex_playz]

Bro, I thought Redstone is simple but bro put algebra in it (He deserves 10 million subs)

[@MrDarkVex]

so great that you explained it in more detail

[@nerdzareawesome9268]

I CANT BELIVE I JUST SAW THE ORGANIC CHEMISTRY TOUTOR THATS ONE OF THE BEST CHANNELS EVER

[@mythicalhacker5]

For anyone who is confused about the xor gate for Bedrock Edition, if you add 2 targets after the input repeater, the xor gate will function properly. But don't forget to modify the two xor gates and the sum so that it also has targets in the second xor. also one more thing, you always need a repeater before the target so the red stone signal passes through it.

[@imvickykumar999]

[@ZTRCTGuy]

That is an interesting way to add decimal number together. I never do it this way, I've learned to start at the opposite side with the left digit, add those together. Go to the next digit and add those together, if this happens to be larger than ten, add 1 to the digit on the left and the remainder above ten to the current digit. Work your way to the smallest digit. Example. 43 + 89. Add left digit: 4 + 8, which is larger than ten so add a 1 to the left which is 12. Then add the right digits together: 3 + 9 = 12. This is larger than ten too so add a 1 to the 12 which is 13. And the remainder above ten stays in the current digit, which is 2. Therefore 132.

For 6:07, we can express it mathematically: C + A + B is... First digit: FD(A+B) + FD(C+LD(A+B)) Last digit: LD(C+LD(A+B))

[@theuserings]

I define FD to be the function that computes the first digit of a number, and LD to be the last digit. As you can see the expression matches the circuit above in the video

[@zxuiji]

You should combine the AND & XOR gates, if you pay attention to the inputs and outputs you'll notice they're the inverse of each other in the outputs that matter, by using them together you don't have to spend anything on destroying the input for XOR, you just redirect it to the AND output instead of the input. A nice side effect of this combination is that it makes it perfect for addition.

The carry extention costs 2 ticks, so the bottom 8 bits would be 2 ticks faster. The only solution would be to delay the bottom 8 by 2 ticks so it matches the top 8.
