- In computing bit length seems to be all people care about with the latest craze being 64bit microprocessors moving into our mobile devices. What does bit length actually determine in our devices? Come with us as we explore come of the fundamentals of bits and what they mean to the data we engage with every day.

Isn't 2^32 actually 4.3 billion?
To this day, I'm caught off guard and astonished at the exponential size and value of 64bit systems
Time travelers mess up the time line they do more damage
0:59 he said 4.3 million instead of 4.3 billion
Really great informations but I was hoping to get more information about the following three characteristics and what they are about:
-data bus width
-addressing width
-register width
With data bus and address lines, the 'width' just means how many bits are sent at one time through seperate wires. An 8 bit data bus has 8 seperate I/O lines to send and receive with, a 16 bit data bus has 16 lines of I/O. It's the same with the address lines, with 8 bit addressing the most memory, (for example), you can access is 256 bytes. With 16 bit addressing it goes upto 65536 bytes, or 64K.
The registers are a bit more complex. The registers are like variables built into the CPU that it uses to keep track of what it's doing and what 'state' it's in. So an 8 bit register can hold a number from 0-255, a 16 bit register can hold a number from 0-65535. I hope this helps.

@@bitaranto546 No Problem. When I replied to you, I thought it said 2 months ago. Not 2 years. LOL. I'm just glad I could help.
@frankowalker4662 honestly one of the most informative comments I've seen on any website. Thanks, I wasn't quite grasping these ideas before I read your comment.

good and basic information it easy to understood
Nice Videos, very instructive! You sound like an intelligent man who took time to learn. I like the way the information is given out.

Cool vid! Awesome to see one of "our" (I work at nxp) chips in it. ^^
2^8 does not give you 255 unique numbers, it gives you 256. You MUST count the number 0 (zero).
Glad I wasn't the only one that realized 2^x CANNOT produce an odd number.
0:45 explains this. Hope it helps!
@@afrodisiac2181 But it doesn't give you "255 unique numbers" it's 256 unique numbers, that is any number from 0 up to 255. 255 is the biggest number you can represent with 8 bits, but you also have to count 0, as it is also a number.
He litteraly says -1
0-255 = 256 numbers
This video had so many factual errors. For example lots of 32-bit ARMv7 CPUs (like Cortex A7/15 etc.) could address 1 TB of RAM. Almost all 32-bit x86 CPUs since nineties (first one was Pentium Pro in 1995) can address 64GB of RAM. 32-bit Intel 386, 486 and the first Pentiums were limited to mere 4 GB.
im emf sensitive and i tried using both 16 bit and 32 bit chinese handheld gaming systems but had to sell them. Ive never noticed any problems with 8 bit handheld game systems. 32 bit system was the worst of the lot for me. Im wondering if i played 8 bit games on the 32 bit system if it would just use 8 bits of its cpu because i loved the ips screen on the 32 bit system, ya know??

Hey Shafaat, are you related to Nabeel or Farhan Qureshi?
A bit stilted and boarderline accuracy.
8b processors can do 64b math it just takes a few extra cycles. The 4bit 4004 came befor the 8008.
Mainframe CPUs have been calculating on the order of 64b+/- since vacuum tubes in the 1940's. Its just the significant digits needed in engineering studies. Even the 16b x86 family had an x87 floating point coprocessor availible since 1980 giving it accelerated high accuracy math, using 80b internally to avoid rounding errors on full 64bit input and output.(built into the same die with 80486 and later)
The length of memory registers is a separate issue, but the amount that a given register length can handle is greatly effected by the type of memory managment.
Anyway for all these reasons mass market 128b cpus are not likely to become a thing.
The reason early IC microprocessors were only 4b then 8b is due to the inverse economy of scale on the physical size of silicon chips. More bits greatly increases the number of transistors on chip. The yields back then were terrible, like 70% had defects even with the smallest cpus, makeing a larger chip increased the odds it would have a defect and quickly approached 100% loss.
The largest gains and cost reductions of the 70s were not from shrinking transistor size, it was from improvment in the raw wafer quality and a new process that didn't peel off masking, first used on the 6502.(The 6502 dropped the price of an 8b cpu from $300 to $25 in about a year due to reduced defects.)
Judging by those numbers, wouldn't that mean that 64-bit architecture could theoretically address up to 18 yottabytes of RAM? I know that in reality it means it is basically unlimited at least for the next very long time, but just curious after you said in 64-bit we are not talking about terabytes of RAM.
You are on the right track, but the correct term is exabytes, 16 of them to be precise (using the binary system, not the decimal one)

Completely wrong. You does not understand virtual memory. Windows can execute 32bits and 64bits programs on the came CPU.
This 32 or 64 bits is addressing mode of virtual memory. Problem is a bit more complicated.
Its more complicated than that. For example, many 8-bit processors will have 16-bit registers and operators.
D.E. Sarcarean like arduino
While on the other hand, the Motorola 68008 has 32-bit registers, a 16-bit address bus and an 8-bit databus.
20 bit address bus. The ALU is 16 bit.
That means I 8bit console is console we don't have a lot memory?

Hi Nicholas, thanks for this very clear explanation. You sound very professional and confident in technology. I sure would want to learn more from you. Please which other videos do you have ?
what do you mean lmao just look at the videos
@@CaidenTMG dude was flirting 😭
This is the most complicated way of saying, that more bits allow for higher memory access.

ok simple qsn , 2^32=4,mm.......... bits right? = 0.5GB , and the whole world says it 4 GB howwww?/????
"64 bits, 32 bits, 16 bits, 8 bits, 4 BITS, 2 BITS, 1 BIT, 1/2 BIT, 1/4 BIT, THEEEE WRIST WAAAACTH!" If you don't get the reference, shame on you.
Dunning-Kruger effect definitely in play here.
Using 64 bit colours using 8 bit CPU
When do you read chip as 8bit, 16, 32 etc with a programmer like Xprog, because default it always 8 bit selected, when do you know that this chip must be read in 16 bit or 32 bit .
I get confuse when I open a programmer and a smal 8 legged eeprom is ready to ready but don’t know if to select 8bit to read or 16bit.
Please help with a simple techniques
Thanks
It is simple information.... But looking forward to receiving more vedio.... Thanks v much Sir ✌️ Peace.
Can I say - 64 bit processors are faster than 32 bit processors? Or again there is any hidden term here?
Sir, Arduino 8 bit + Arduino 8 bit= 16 Bit. Is that possible??
I am trying to find out what the actual size of bit in inches. I understand binary. Before it blows my mind, how many transistors you are on a chip
Thank you for the video. The explanation was clear and concise :)
Strong knowledge💪
You forgot the Differences between the Graphics.
2^8 = 256, 2^16=65536 ...
Do you know if any one I'd working experimentaly on 132bit cpu's.
Please add subtitles
Awesome
Now I wonder where y'all got the formula who really is to credit for this technology bet you his. Name start with d
Think about it manipulation somebody took credit from somebody else's hard work but in the end every lie will come out everybody who involved will be revealed

If you are not already... You could be a college professor.
Although, modern 64-bit processors only address RAM using 40-bits which is only 1 TB of RAM.
2 decade old first generation x86_64 memory controllers are hardly "modern". Most at the moment are 48b virtual and 52b physical. Though intel has gone to a 5 level paging tree on some models giving 57b virtual (still 52b physical as I recall which is part of the original core standard)
That extention of x86 was kind of an emergency hack anyway, the manufacturers even said there will be new tech by the time we get to the 52b limit so no point in reengineering it now
thank you.
And i tout that we already live in the 10.000 bit range, but if cpu’s are
Only 64bit , then how is the ps2,dreamcast etc,, an 128bit system???
But what is it ?? I readed that the ps2 may contains 4 32bit cpu’s to function like a real 128bit system,not sure,, am mean if 32bit & 64bit cpu’s getting just overclocked to get more speed out of it, rather then increasing the bits, then all i can say is that we are misleaded all the time ,, am mean may an 8bit at 8 mhz can be just equal a 16bit cpu at 1mhz etc,, not sure
Thx
There are 64 bit MMX register/instructions, 128/256 bit XMM register/instructions, 256/512 bit AVR register/instructions on a modern Intel/Amd x64 CPU, but only address-register for 64 bit addresses in memory and there is no x64- mainboard that have ram slots for all 64 bit addresses.
Thank you for your information 🥰🥰🥰👍👍👍
So the next step is a 1024 bit CPU.
Hmm i think I’m going to check my recommended
Finally I understand how bits works.

super bro. explanation
2^8 = 255 ?
2^16 = 65535 ?
...
how the parity number raised to power can be odd ?
I think it's because of 0 counts? I'm a noob so don't sue me. 2^8-1 or something.
@@KillJD check the 0:57 here is no "2^8-1" but 2^8 =...; 2^16 =... etc.
@@wegi9621 Still, when we write: 2^8=255 this is WRONG and leads to confusion. One can say: The RANGE of values you can have with 8 bits is "FROM 0 TO 255", but not: "2^8 EQUALS 255"; everyone can do the math: 2^8 equals 256.
@@johnni5254 exactly, also counting from 0 to 255 we got 256 combinations
@@johnni5254 Yeah the zero counts so it's indeed 256 numbers in quantity and not 255

For saving a video, what is best 8-bit or 32-bit?
64 bit
Thanks

Great video!
Great video!
DSP??
If we will get to 128 bit color, do we need more gpu power?
R313 J283 Certainly.
even 32-bit color depth exceeds what the human eye can percieve, so i doubt we will ever need more than that.
Probably not for real time graphics.
