I inspired for make my own cpu watching this videos! But, i have only 1 question: what is this program? it looks pretty useful!

@@code_stream_yt he made the program himself and there are probably links in the description. It’s called Digital Logic Sim

@@code_stream_yt I am using the android app - "Logic Circuit Simulator" for simulating all this on my phone.

The dislike button is disabled by youtube, not actually at 0 dislikes.

@@feha92 I know… I was more talking about all the positive comments.

I'd definitely love to try making a simple electronics simulation! I'd probably keep it separate from the digital logic sim though, since I also like the simplicity of that.

@@SebastianLague I also really like the contrast to a real breadboard!

Wait a minute… 17 hrs ago….. wierd

@@SebastianLague Also would be nice to add transistor logic. I am currently using a program called Logisim Evolution to make a 16 bit computer at the transistor level. I have considered writing my own program that would better handle transistor logic but I have no idea how to do that.

@@dr_mafarioyt4313 it's called being a patron baybeeeee

Thank you! I sometimes wonder if I’m being silly spending time on these sorts of minor details, so I’m happy it’s appreciated :)

@@SebastianLague Definitely keep it up, but only as much as your motivation allows it 👍

@@SebastianLague Those "minor" details really take the videos to another level! It's amazing

@@SebastianLague computer topics are typically so bland and obviously technical. Having these sorts of satisfying animations really help with making it enjoyable to watch!

@@SebastianLague No, they make them so much easier to digest.. its why I retain things from your video above others.

I’ll definitely consider doing a video about it in the future!

@@SebastianLague Yes, that would be great!

Yes, and i like the fact that many of theese things you can build in minecraft, like an alu, a 7 segment display or even a 4 bit register

​@@TechCircuitBreakdownIt makes sense since you only need simple AND and NOT gates to make all of that, which can be done in Minecraft thanks to redstone...

Ben Eater fans unite!

I am currently doing my degree in electronics and computer systems and that is wholly thanks to Ben Eater. He makes stuff so interesting to learn

Im currently building his 8 bit breadboard computer and this series helped me A LOT. So i agree more than 100%

Don't forget the wonderful "Nand to Tetris" course!

AMEN

You've ignited passion in me and I breezed through half my sem with this series. Thank you @sebastianlague

You always motivate me to do more programming! :)

Lol, I introduce Sebastian to others by referring to him as my spirit animal.

@@terristen lolll

@TooMuchYak yes?

That and the fact that chip form factors typically have 2,4,8,16,ect. pins so they would have sat unused otherwise, which is pretty wasteful.

Oh that's really clever. Thanks!

it most likely uses a demultiplexer for switching, turning 2 bits of input into 4 exclusive signals

@@aonodensetsu ur talking about a decoder?

@@dexterwolford no, i'm talking about a demultiplexer

and it took less than half the length of a lesson

this and a 15 min mattbatwings video combined can teach more about computers than getting a computer degree

Interesting, thank you!

Yeah, usually (at least the few chips I have worked with) you get multiple chip selects/out enables to save you a few external and gates. Sometimes you even get one inverted (active low) and one non-inverted because this makes external selection circuitry easier. Also for registers having multiple inputs can sometimes allow easier "stacking" (not really the formal term I think but basically using more than one chip in parallel to increase the bit width or similar), because in these cases some select signals might differ (only have a 8 bit bus but want to work with 16 bit data in this calculation? Easy! Have one "global/external" store connected to one write enable pin on both chips and the other one connected to a toggle latch. This way the first clock pulse will latch the first 8 bit in the first register and flip the toggle latch so the second clock pulse will store the second 8 bit set in the second register.)

agreed! I thoroughly enjoyed the first installment, and enjoy even more how each one builds upon the last!

He's being consumed... Eaten, you could say.

Maybe his mouse was? - and just perfectly timed the clicking to when he clicked with the real mouse

The mouse movement was definitely automated in some way, not sure if it's actually a part of the circuit simulator code or some other program that automates the mouse, but it's too smooth to be real inputs

Im almost positive thats exactly the route this series is going to take and im super excited for it!

@@jetison333 would indeed be really cool to see. Sebastian is starting to look more and more like Ben Eater and I'm all for it

@@matthias916 Ben Eater and Sabastian Lague are the best youtubers I've seen

The instruction format in this case is really funky: 4bit - external memory/stack/input in red, 4bit - read address in blue, 3bit - operation type or store address in indigo. But you can make an instruction decoder and design something more elegant if you want to, just grab the software and make your own. What the circuit in the video really needs is more explicit branching with a comparator. But you'd probably add a small stack and stack pointer with that, to make sure it's Turing complete. At this point the circuit simulator devolves into a CPU architecture designer with no way to synthesize the design.

That would be possible to .

Yes, that would solve the issue of bus contention, but would limit your design to only working for 4 registers. This approach (while somewhat more "risky") allows for much greater modularity.
