What is ARM? (& Why Is It In Everything Now)

Apple with their new ARM M1 chipsets, Microsoft already using ARM processors with Windows, the entire mobile phone industry running on ARM chips, you might be wondering, "What is ARM?" and why are we seeing it more lately. Well, in this Decodr episode, we'll talk about what ARM actually is, the difference between ARM and x86, and why more companies are making ARM chipsets lately.

Really well explained in a short time! Being an electronics engineer I know topics like these have so much depth but you did a great job in explaining the fundamentals very clearly! Loved the production too!

Recently discovered this channel off a MrMobile link
Love the content man

[chriss]

Arm stands for Acorn Risc Machine originally as it was their own in house design and manufacture. Know this as grew up in the UK as all schools had them in abundance. It was the education computer of choice here.

Hey, from one David to another, I really enjoyed this! Thanks! – David P.

[minas]

first lol finally someone explains what arm is

[breathtakingblue]

Shout out if you're from Cambridge UK! 👍ARM is just down the road... And I remember those Acorn computers... and Tandy computers back in the 80s.

[rufdymond]

I suppose coming from the UK and being a tech guy, I have a good understanding of who ARM are and what they do....been aware of and used their tech since the 80s in the BBC Micro Computer. However its goo to see someone explain exactly who ARM are, and deliver that information to a wider audience.

[Richiebxrry]

The content on this channel is just amazing. The quality, the clarity in his explanations and no gimmicks. Much love from the UK

[openbabel]

ARM chips have typically been optimised for unix, maybe sparc and linux...super computering glabally would favour linux or unix on arm or risc 5 chips.

I could listen to this guy describe paint drying. He, Michael Fisher, MKBHD and Jaime are the best tech youtubers. But Unlocker is the most relatable.

[moranmono]

I think that the main reason is that the battery technology is still very limiting and we want smaller devices with longer battery life, that makes the arm based chipset the technology to go to

[Mike-whdq]

....'We need to talk" so I listened and learned !!! Thanks for the informative and concise explanation to include some subtle humor!

[ujjawaltomar]

One of the best youtube creator in tech explained series ❤️

[ntemples]

What an absolutely brilliantly informative video! Thank you! Certainly filled in all the blanks for me and I didn't realise that Arm actually originated from Acorn which incidentally built my first computer the Acorn Electron 37 years ago when I was 10!

[jamieharper]

Awesome explanation man, I also have the benefit of not having to search what x86 is now too (two birds one stone lol) 😅 great video format too, as someone with adhd, even I managed to stay engaged all the way through lol 😁 keep up the great work dude 😎

[frozenbeverage]

Really informative, still loving the vlog style, so much so I've watched it twice. Stay safe man!

[isaahyar]

Its going to be challenging for AMD and Intel as ARM and RISC-V are vigorously pushing their ISA moving forward beyond the boundaries of what CISC can do. They are more efficient and more powerful depending on the design for their respective use cases. Its going to be an exciting time for the future of computing

P/S: Please do a Decodr episode about RISC-V. Interested to see in your point of view

[JD-kfki]

Could you explain more about ARM Cortex processor?

[JB]

I've heard that RISC isn't really defined by having fewer instructions, even though that was the biggest distinction early on. By removing memory accesses from most of the instructions and having a fixed width, they become reduced in complexity. Nothing rules out having a lot of them. RISC is more of a Set of Codes for Reduced Instructions.

x86 translates to RISC micro ops, but because the instructions have a highly variable width and many memory accessing modes, they require a complex decoder. ARM can get more done with less silicon, since there's less complexity between what the software wants to do and how the CPU decides to do it.

Very informative Dave, I've never understood the relationship with ARM but you made it very easy to keep up with 👍. Also the format was very nice, how was it different to the usual stuff?
