The CPU design used in the video is copyrighted by John Scott, author of the book But How Do It Know?.
There are a few small differences between the CPU in the video and the one used in the book. Those differences are listed below but they should not detract from your understanding of either.
CONTROL UNIT - This component is called the Control Section in the book. It is called Control Unit here simply because that is a more common name for it that you might see used elsewhere.
LOAD INSTRUCTION - In this video, what's called a LOAD instruction is actually called a DATA instruction in the book. The Scott CPU uses two different instructions to move data from RAM into the CPU. One loads the very next piece of data (called a DATA instruction in the book) and the other uses another register to tell it which address to pull that data from (called a LOAD instruction in the book). The instruction was renamed in the video for two reasons: 1) It might be confusing to hear that the first type of data we encounter in RAM is itself also called DATA. 2) Since the LOAD instruction from the book is a more complex concept, it was easier to use the DATA instruction in the video to introduce the concept of moving data from RAM to the CPU .
IN and OUT INSTRUCTIONS - In the Scott CPU, there is more involved in moving data between the CPU and external devices than just an IN or an OUT instruction. That process was simplified in the video to make the introduction of the concept easier.
ACCUMULATOR - The register that holds the output of the ALU is called the Accumulator in the book. That is the name typically used for this register, although it was simply called a register in the video.
MEMORY ADDRESS REGISTER - The Memory Address Register is a part of RAM in the book, but it is a part of the CPU in the video. It was placed in the CPU in the video as this is generally where this register resides in real CPUs.
JUMP INSTRUCTIONS - In the book there are two types of unconditional JUMP instructions. One jumps to the address stored at the next address in RAM (this is the one used in the video) and the other jumps to an address that has already been stored in a register. These are called JMP and JMPR instructions in the book respectively.
MISSING COMPONENT - There is an additional component missing from the CPU in the video that is used to add 1 to the number stored in a register. This component is called "bus 1" in the book and it simply overrides the temporary register and sends the number 1 to the ALU as input B instead.
REVERSED COMPONENTS - The Instruction Register and the Instruction Address Register are in opposite positions in the diagrams used in the book. They are reversed in the video because the internal wiring of the control unit will be introduced in a subsequent video and keeping these registers in their original positions made that design process more difficult.
OP CODE WIRING - The wires used by the control unit to tell the ALU what type of operation to perform appear near the bottom of the ALU in the video, but near the top of the ALU in the book. They were reversed for a similar reason as the one listed above. The wiring of the ALU will be introduced in a subsequent video and keeping these wires at the top of the ALU made the design process more difficult.
Thanks! I still don't understand it, but now I know what exactly I don't understand
+Yenchey lol.. at least you know somethin xD
Scorpio X no... I just wanted to know how CPU works xD but I also play Minecraft sometimes ;) and I'm not really into redstone... My biggest creation was an "escape" map with maybe 5 chambers with redstone circuts...
+Yenchey i think the author of that book asked this guy to make the video un-understandable so that his book sells more.

Just understand that ram and Cpu get data from each other and when the binary numbers are added together they create memory and it gets stored on the cpu
I'm a software engineer with several years experience. I've always had a vague idea of what these components do, but I've never been able to wrap my head around how they do it. Your explanation was so eloquent yet concise that these concepts that have always escaped me suddenly clicked and made perfect sense. Great video!
Nice!

@@darylallen2485 That was NOT the guy... He was just a clever academic that summarized and abstracted other peoples constructions or designs, and got far to much credit for it. One of the first that actually designed and built a fully programmable CPU and computer from scratch was the German Civil Engineer Konrad Zuse, in the 1930s.
@@herrfriberger5 You are totally correct. Von Neumann basically just created a simple model from the complex architecture of a CPU back in the day.

I love how you managed to explain something so complicated (seemingly) in such a simple way that I understood it. Thank you!
8 years ago an awesome guy made this masterpiece and disappeared
where are you man? the world needs more of this.
Right off the get go my mind froze. When he made the statement about the clock turning on and off two times per second on the 6502 chip, I was okay. Then when he said that modern CPU's turn off and on billions of times per second...that is when I lost it. I cannot envision a second divided into a billion parts. That fact in and of itself is damn near magic to me. Oh, I can understand it at an academic level. A chip running at 5 Ghz is 5 billion times per second. Okay, moving on...It's the visualization of that process that really ties up my noodle in knots. Almost magic to me!

+Täking Thë High Roäd Compared to how a car or a refrigerator works, this is pretty much magic.
+Täking Thë High Roäd There are many subjects in technology and science that you have to understand that your intuition would not be capable of simply "getting it". You intuition is flawed for the modern world. I can't imagine a light flash on for one billionth of a second, but I don't care, all I know is that 1 billion of those flashes put together would be a light staying on for a second, if I even wanted to bring it near to something I could intuitively get. Or I could not care, and I don't and just say it happens a billion times a second. Once you let go of your intuition you can carry on to quantum mechanics.
I was so fascinated by this explanation. It just had dozens of little lights turning on in my head. Really really helpful! Thank you so much!
👍amazing
Amazing how it transformed the impulse firing in your brain 🤝
I love how you explained this. It makes perfect sense. I had no idea that the processor processes one instruction at a time at that rate of speed.
maybe ..but just how does it process one instruction at a time if they are only electrical charges.
@@johnpro2847 it's a maze, if the electricity follows a specific path it reaches point were lets say for example that lights turn on and we see those lights and understand what is means, how? When you see what i wrote here its because of the lights or should i say pixels that are tunred on , its a siple black and white background, if we want colors it's the the same process, great now you can see images too.

I have to watch this at twice the original speed for my learning nature(...) but, the voice has a very good pitch and tone for studying, and not hurting my hyperacutic ears or putting me to sleep. Thank you for that. I was confused for most of this., but the entire knowledge of this video is now somewhere into my subconscious stream. Will watch again sometime.
EXCELLENT description! This has made things a lot more clear about the CPU on my obsessive journey into Digital Design. Many thanks. Just bought the book from Amazon.
I can finally see how stupid I am I don't understand one bloody thing
Nah, you're not dumb. This stuff really is hard, it takes time to get it down :)
lol
I'm with you bro
You have to know computer architecture, basics in assembly language and introduction to programming to understand this.
You don't need to understand basics in assembly langauge to understand this. You need to understand this to understand basics in assembly langauge though.
After reading the book, I rewatched this video, and finally, I understood the whole process. It's mindblowing!
the computer is quite the advancement from the abacus and the calculator , mindblown
@Texsic It's awesome!
Tell me
Love this kind of content.
Will be looking at this book.
I’m currently working on getting my CCNA with Cisco!
Awesome video! Now I have somewhat of an understanding of what's going on when I look at the internals of a computer. Thank you very much!
After seeing this I'm amazed a computer even works
One of the nicest yet compact video for understanding actual hardware and software communication inside a CPU.
Thanks a lot!!
This is what my teacher told me to study for my project even though my project is only to make a digital voltmeter. Idk if I could be able to redescribe those information in my report but you have my appreciation regardless. Thank you
Excellent video! I've been involved with computers since the 1960's. Your video (and Scott's book) are both excellent introductory sources for beginners. Thanks so much!

Bro start playing Minecraft and this will make a whole lot more sense.
HAHHAHAHA! Best comment ever
@@KungKras Also out-of-order execution and speculative execution XD
How did someone even think of this and invented it, it's mind blowing.
It started off very simple. A simple class in electronics would give you what you need to start designing your own processor. Remember that these engineers were developing something that didn't even exist, and when they did develop it, it was revolutionary but crap compared to modern processors. It was not one man that invented it in one space of time, but millions of people over many years.
A lot of people making baby steps over 120+ years. It's amazing what humans can accomplish.
yea its kinda like cars. The first car was horrible but it revolutionized modern society today. You could literally WALK faster than the first car invented, but ofcourse over many years (which isnt even that long) we now have super amazing cars that can go as fast as airplanes at takeoff speed. It is amazing!
It's like car engines and transmissions. It started very simple back in the old days so that every blacksmith could repair it but every generation added more and more stuff to make it more powerful and efficient so that nowadays you feel stupid if you watch videos that explain how modern engines and transmissions work.
(i have experience designing minecrzft CPUs) it goes from a clock and some more stuff, then goes to more complex stuff, then to Scott cpu
This was perfect, a great base to learn from! Well done sir
When I first saw this video, I was really confused, but after learning Computer Science Principles and building my own pc, and watching it again, I can get a general idea of how it works. Thank You!
bro what hahahahaha
This is so fascinating and complex, we take this for granted so often. Excellent video!
true!!
This video made it very clear to me from a distant observing point. I studied electrical engineering and I was introduced to digital systems, transistors, logic gates, registers, etc .. also I have a programming background but I couldn't fit all of these information in a proper way that allows me to understand how a CPU might work. Now I can say I could make it to the first 1% of computer engineering and I'm depressed.. note that the video talked about building blocks like (ALU, CONTROL UNIT etc) there is more hell inside!
❤
My computer architecture teacher should show this presentation in class. We student literally don't have any idea what's going on inside it. I always thought it's beyond my comprehension to understand how CPU works only scientists can exactly know. That person should be called talent who explain better than other. You are one of them 👌
I'm new to the computer science field, and this 20 minute video explained my past 10 hours of lectures. thanks so much!!!
Thank you so much for the knowledge you’re sharing. I’ve took so many courses , computer architecture, integrated circuits ,multiple Assembly language , etc , etc and this video just puts all pieces together 👌🏿🙏🏿🙌🏿
I have studied it in detail when i was doing my engineering, but I really loved the way you explained it so well in 20 mins, when I first saw the title I wasn't expecting it to be this good. Great Job !!!!
Will checkout other videos on this channel too
Hey, I can kinda assume that you're Indian from the name but I'm sry if you're not, but I've just finished my secondary education and I would give anything to learn these things in all the detail there is, so can you just tell me the name of the course or which places I have to look at ? Thanx

it has been a week that I am learning about this topic and i can for sure say that this was the best explanation i've heard.
What a mind blowing video.. eye opener what a miracle computers are... Ohhh thanks frak for nerds and geeks, being laughed at, inventing the most miraculous and most important technologies for human kind. My mind just cannot percieve the insane rate of all of this happening and much more on todays even cheapest CPUs and all so easily accesible and portable. Fantastic..Thank you for the video.
+Mikee CZ ugh, I hate the world 'miracle'. It makes it sound like it is some mystical thing that is given by the gods.
+Mikee CZ yeah, electronics is pretty much the only industry where the improvement is exponential. Moore's law is pretty nuts and it went farther than anyone predicted. And now some of these complicated integrated systems cost only a few cents to produce and sell to you.
AVN WX Except pretty much everyone into electronics, and Moore himself. Moore predicted it, hence Moore's law.
Moore's law was merely an observation, and it was only made possible by the process engineers being able to shrink down the chips so much. Over the decades it's been repeated said that Moore's law was in trouble due to the problems inherent in lower process nodes, yet there were a large number of innovations in order to keep it going.
AVN WX And isn't that a big part of what science is? Making predictions about the future based on observations past and current?
This video just leaves me with even more questions. Like how does the control unit work? How does the cpu know when to do what? I mean it cannot think by itself so how does that work. Also how is a program I wrote processed. I can't even explain my questions
+Toxicz There is something called a Program Counter (PC), that reads all the instructions and sends them to registers and CPU accoridngly. CPU actually knows nothing, it just reads a Program Counter (PC) and does what it PC tells him to. Your second question: The program you wrote in some form of programming language is first being compiled, than it is translated to a machine code(a language that computer can read), and from than on it does what i wrote you at the begining. Hope this helped
+Toxicz rewatch the video =D it explains most of your doubts. The CPU knows when to do what because of certain instructions, instructions that are coded and specified with each algorithm.
+Toxicz This type of thing is pretty much true for all knowledge the more you know the more questions you can ask about what you know.
+Toxicz The control unit knows what to do for each instruction with a series of decoders (one for each instruction type) which only activate if the instruction matches a specific binary code. For example if the instruction has a code (lets say 2, which would be 00000010 in the register) that means to jump to a new position, it would know that it is a jump command because there would be a dedicated circuit in the control unit that would only be activated if the appropriate instruction was in the cpu.
Beyond this it gets into logic gates and if you want to know how all that works, I would look at redstone tutorials (yes redstone, from minecraft) as redstone is basically binary circuitry in disguise. As to how it knows when to do what, it uses a rising edge mono-stable circuit (getting into logic gates, basically a circuit that makes an electrical pules on the activation of its input wire but does not do anything more until its input is turned off and on again) and a falling edge mono-stable circuit (activates on the input turning off) hooked up to the clock wire so it does half of its functions when the clock goes on and the other half when it turns off. The mono stable-circuits are often hooked up to the various set wires of the registers through an and gate with the other wire connected to the output of the binary decoder that detects if the right instruction is activated. Hope that helps and is readable.
And that is right. You can't study such things in 5 minutes, there are thousands of pages in books explaining details. Anyway, it's tens of years of experience.
It's very useful what your guiding. The top u explainef is directly nicely set into my brain and i can enable it when ever

This is brilliant. For me learning this 10 years ago when i was in high school is very much waste of time, now i have learnt to appreciate and being grateful to work with computers
This is probably the best video about CPU architecture and working I have seen in my life, thus far.
had to keep going back and forth but got the gist of it. Still insane how trillions of instructions are done. Can't wrap my head around the true scale
This is by far the best visualization I saw on CPU explanation
After messing with redstone and building a minecraft computer it is worlds easier to understand this.
Same dude
That's what I thought! Just everything clicked.
doing that right know on ORE
Kishore G. originally I built alu units out of just connecting and gates because I knew that would work. of course, I learned about xor gates later on. you can build a computer just by messing around, it just takes time
Minecraft deserves some credit for this, now that I think about it. It's a game with two basic building blocks out of hundreds, redstone and redstone torches that could be used to make a computer that can actually run a game. I wonder if it would be possible to create a computer in minecraft that could possibly even run a version of minecraft in 1080x1920 resolution, it would take years to build (or using a native plugin, you could have it built for you, like the one used to recreate the Netherlands in minecraft.)
I had to teach a class on this subject, but couldnt put it in words. This helped me a lot. Thanks
You make me love the computer architecture course subject

Ok and how the fuck did we(people) come up with this such a simple thing that has only 1 & 0, and at the same time very very complicated thing? couldnt there be an easier way to make a "computer"?
emmanuel kayiwa a chromebook will contain the same hardware, its just a different OS running on there
emmanuel kayiwa If you don't know crap. DO NOT mislead others!
This is the easier way.
"and at the same time"
We didn't spontaneously figure out how to make a microprocessors. It evolved from many other simpler contraptions, first with vacuum tubes and then circuits with transistors.
12839712894710aaa No, the first ones involved using gears to add numbers, and a machine that read cards with holes in them to weave patterns into a cloth
THANKYOU!! For this amazing explanation 🙂
Thanks, that explanation is very clear and interesting!
Wow, I just learned how a computer fundamentally works in a total of 20 mins. Great video In one lesson, well done.
i don't care how advance an outer alien civilization can be compared to us, this is science ficition to me. I understand about computers but how a CPU works... as Steve Jobs would say "it's magical".
Read up on transistors and stuff and it'll make a little more sense =)
I think I got the basics now myself.
It's still damned complicated and you'd have to have an overview of increadibly many things for a program to make sense all the way, but I think we could make something like say a basic text adventure game with this kind of logic fairly "easily" =)
(As in if you picture every single bit in your mind and remember it all then you might actually manage to follow what happens)
Well...
You kind of can get something like this if you think of a grid where you have an input a set number of true or false statements in one end and get a set of true or false statement in the other end by having each step check if the previous one where two true statements, two false statements or one of each.
Given the input pattern you get a set exit pattern.
Now imagine that you have a input pattern not given by a input you control but predetermined (by software) and that this changes based on the exit output from the last step in the process.
That's basically all a CPU really is.
It really just checks input patterns to give an exit pattern and that ends up in memory/storage to give it new input patterns again.
With one input pattern you might get an exit pattern like say light up one light bulb and with another you turn it given the stored input it's compared against.
That's done for every single pixel on your screen with predetermined patterns of signals at predetermined "intervals" (not really but meh) will trigger a output signal equaling a complex on and of pattern on your screen like say the letter A.
Now add another "CPU" like your graphics card that process the output and compare it with other output at a different point in the code and you can get something even more complex out of it, like a pyramid shape calculated and then calculated how it would look when seen in 2D (on a screen) and then calculated into pixels turned on or off...
You get the picture I think...
I hope that made it a little easier to imagine...
I can try to find some videos on here to show you the concepts I'm talking about later.
But really, a computer is really, really dumb.
It just does millions upon millions upon millions of tiny calculations so fast that it seems smart even if it isn't.
Ps. I get it if this don't make sense right now.
I kind of wish I could talk to you in person for a couple of hours, I think I'd be able to make it make sense for you then.
It's not magical, it's materialistic like all of reality. It is therefore easily described scientifically and it's theoretical foundations is basically mathematics, certainly able to be learned and not that difficult. Since it's mathematically oriented, it comes as as unfamiliar jargon to most people.
Gaius Caerulius Verus Yeah, just hard to explain it in a simple fashion.
Been trying lately to do so with a room with two light switches and two people using a code to communicate through the light switch, using the light to help them decide what setting on the switch to use next.
Not sure if that's good enough...
Spectacular explanation for me good sir. I had no idea and now I do. Thank you
Brilliant explanation! Very, very helpful! Thank you!!!
