If you are buying an Android smartphone, a tablet, or Chromebook then it will help you to understand the naming scheme for Arm CPUs. In this video I cover the Arm Cortex-A range, the Arm Cortex-X range, as well as Arm's microcontrollers (the Cortex-M range) plus a bit about Neoverse.

very good video! for the microcontroller, there are also present in large numbers to control the different subsystems inside a big SOC. fun fact, was at Arm in an internship when they did the transition from ARM to Arm. got merch with both logos 😀. i found it very funny when people correct me on the pronunciation of Arm😁.

Well done guide, thx Gary! Arm is one of the most revolutionary designs. The legacy of folks from Acorn is timeless and lives forever. Maybe u should make a little history review video, specifically situation when they were testing first Arm chip design, when board was powered off and chip was still running. I think this was a HUGE Heureka moment in chip design history!

Having first encountered the processor family back in 1987 in the form of an ARM2 in an Archimedes A310, I'm sticking with ARM standing for Acorn RISC Machine.

There was also a cortex R line ( real time) for modems , disk drives for example. Scale out with N2 Neoverse does not equate to better “multithreaded “ performance just overall better performance per CPU ( CPU performance= performance per core* number of cores.

Do Arm have any GPU architectures or just CPU architectures? As many SoCs have GPUs, whose architectures (if not from Arm) do they use for that?

@GaryExplains 6 ай бұрын

Yes, the Mali GPU range. I have several videos about them on this channel.

SoC naming is the most confusing part. But now I know why sometimes the Arm architecture got an A at the end.

for assembly language programmers, flat assembler is available for ARM in the form of the fasmarm package. it's non-native and runs as a cross-assembler on x86.

You forgot to mention the Apple connection to the birth of ARM. You could say Apple was the mid-wife. Apple was uncomfortable with buying the chips from Acron and wanted them to spin out the chip division as an independent company.

Fun fact Intel used to make arm chips.

@Salfordian 6 ай бұрын

And going back into them "Intel and ARM, arguably two of the most important players in modern chipmaking, are joining forces. On Wednesday, the companies announced a “multigeneration” agreement to optimize Intel’s upcoming 18A fabrication process for use with ARM designs and intellectual property. The deal won’t see Intel’s Foundry Services division produce chipsets for ARM. Instead, it will make it easier for ARM licensees, including the likes of Qualcomm and MediaTek, to hire Intel to make chips in the future."

@g137hampton 6 ай бұрын

It's interesting that Intel at one point had an Arm architectural license and developed X-Scale processors but then sold this to Marvel in 2006, a year before the iPhone was released. This was horrible timing and has kept Intel out of the phone market completely.

The biggest conspiracy around Arm is that because linux is so x86 centric, Arm gave phone makers the limitation of blobs and hence all the politics around Android phones

Why we need stm32 controllers in friggin coffee makers?

@GaryExplains 6 ай бұрын

Is that a serious question? My coffee machine has sensors for when the water is hot enough, when the water level in the tray is too low, when the milk jug is attached, etc. It has different buttons, and different LEDs to tell me when it needs descaling etc. These are all very simple functions for a microcontroller that costs just $1 or $2.

@davidgari3240 6 ай бұрын

I think his point was that coffeemakers ran fine without chips capable of running an internet-connected, multi-tasking, real-time, multi-user, monkey-navigated, virtual-memory, operating system at 100 megaFLOPS. My toaster crashed the other day, so I tried downloading an update, but my self-aware vacuum cleaner beat me to it.

@GaryExplains 6 ай бұрын

If that was his point (which I am not sure it was) then it isn't a good point. I could live in a wooden hut just "fine" or live off insects and forest fruits, but that isn't an argument for actually living life that. I am glad my coffee machine has a $1 microcontroller in it. It makes it a better coffee machine.

@Salfordian 6 ай бұрын

All high cores unlike the M3 if I remember rightly so if the M3 had the same setup that would beat it so hardly a fair comparison

@GaryExplains 6 ай бұрын

@Salfordian Unfortunately it isn't as simple as that. The point is that the M3 has all high performance cores and yet good battery life and good thermals. The M3 isn't a big core only setup because if it was then it wouldn't have the battery life and thermals that it has now. So the difference is that Qualcomm has managed to create a big core only setup and yet keep the battery life and thermals. You can't just say "if the M3 had the same" as the point is that the M3 doesn't have the same set up because it can't.
