You are a gift from God to us. Being an electronic engineering student, I have learned more information from your videos than my 3 years university classes. Thank you for this amazing series and I hope it will continue that way. God bless you. 🙏♥️

Thanks for "showing the world" how simple the computer really is. For others: the input signal he generates in the final stage is an assembler instruction (move data from here to there, prepare data to be counted, store the result over there and so on...). Your normal programming language instruction C = A + B gets translated to "move A and B memory locations to input, make their sum, move the output to C memory location" and the only meaningful difference between Sebastian's simulation and your computer is the scale and scale related optimizations.

Hey Sebastian! I know you probably won’t reply but I just wanna say that you’re literally my biggest inspiration in life. I just made a solar system simulator because I loved yours so much. Thanks for everything :D

This series is honestly amazing. When learning stuff like this in school, they are nothing but boring information, but when presented this way, everything changes. I don't know why, but seeing all these components work with each is very satisfying. Regardless, amazing series and I cannot wait to see more.

I like how this series is basically a presentation on my 300 level circuits courses in college. Real blast from the past, and highly educational. PSA if this grabs you, consider a Computer Engineering degree!

When talking about the 4 bit register, i think there are 2 reasons for the store signal and data out signal having 2 pins. Firstly, the 16pin dip package is a lot more common then 14, so we likely have those pins anyway. Secondly, when you talk about the issue that 2 chips could output onto the bus at the same time (14:11) this can easily be solved with those 2 pins. If you give each chip a different combination of not gates before their data out, it acts as a mux. A could have no not games, B could have a not on pin 1, c on pin 2, and d on both. Giving you the same inputs as when you had the mux chip. Then they can no longer output at the same time since each chip has an unique combination of inputs to enable it

@SebastianLague

Жыл бұрын

@reinei1

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.)

I've been a software engineer for like 7 years at this point, and I've always abstracted in my mind the behaviour of this low level components... this is the first time that I get to understand how all of this works from the bottom up, and it's SO cool. Be sure that i'll send a lot of people your way, because this is pure gold.

I've never seen it all put together like this before. When you wired everything up at the end and started (essentially) running CPU instructions by hand, I got goosebumps. Just beautiful.

Absolutely loved this episode. When you put that calculator together and showed it storing numbers, doing basic calculations and displaying the results, I finally saw the computers we have today emerging. Awesome stuff!

I was totally bummed when I I watched this series before, and it wasn't continued. Thanks for bringing it back!

This series combined with the game Turing Complete makes it perfect to understand and put into practice how a computer (or microcontroller at the moment) works.

this is making logic components so intuitive and easy to grasp and remember!

Absolutely love this series. Can't wait to watch this one. Keep up the amazing videos!

you are a bright light in the programming community. keep doing you!

This series is brilliant! I love watching it whenever a new video comes out. You're a great teacher. Thanks for all of your videos.

I'm enjoying how your little simulator made for this series is improving every video.

Just found this series and it is great! I enjoy how it focuses on the theoretical part (not having to worry about timings or electronics too much) but also mentions the more practical problems as well. Great work

This series is just awesome, I can't wait to see how far you'll go. Also, I can just hear your smile in your voice and it's really awesome, I wish all people were this enthusiastic about the things they teach

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.

This has been such a cool series. The progression to this point has been so smooth, you can tell you put a ton of thought into it! Can't wait to see more

You're a hero! This was such a good series. The way you demonstrated everything on your simulator, which was designed to be very easy to read, made this really easy to follow. Also, it's cool that you actually made a simulator and didn't just draw diagrams.

This man turned electronics into art

I'm curious how far you'll go with this stuff. Can very easily see you designing and building a 16 bit CPU and writing some instructions for it.

Been following your series since the beginning and I love the way you teach the subject ! I'd definitely be interested in videos on electronics aswell, as I believe it makes the link with the "real world" clearer. Kudos for the great work Sebastian !

Sebastian, you have been doing the god's work, teaching us how the computer works by simplifying everything which goes on inside. I hope you continue this and keep on working on the simulator software so that other engineers and students can experiment on different circuits.

I cannot stop wondering how you move your mouse cursor so perfectly. Every line is perfect, and every movement is smoother than a sin wave.

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.

I absolutely love these videos. I've been following this series since the first episode. Recently, I finally decided to download digital logic sim, and I spent the day building up latches, and flip flops, and registers, building up adders, and bigger adders, and bigger adders, making an ALU, making various sizes of RAM, a simple counter, and I was able to assemble them all together into a functional 8 bit computer! It was some of the most fun I've had in months, and I'm so proud of how it eventually turned out. There are still some things that I could do with it to improve it. It's not the best 8 bit computer, but it's mine. I built it gate by gate, chip by chip, and I'm very happy that I did. I hope you continue to develop Digital Logic Sim, and I hope you continue to make these videos! They're a wonderful resource to help people understand how computers work in a very fun and understandable way!
