The name ARM is no longer strange to those who love technology anymore. It can be said that ARM is the revolution for handheld smart devices. And certainly in the future it will go even further.
Despite being so famous, I’m sure not everyone understands ARM in general and ARM architecture in particular. So today, let’s take a closer look at ARM.
#first. What does ARM mean?
ARM is an acronym for the phrase Advanced CHEAPISC USAachine (ARM), developed by ARM Holdings, is the owner and representative of all ARM architectures in the world today.
In essence, when it comes to ARM processors, this processor is designed based on the ARM architecture.
ARM Holding itself does not produce any processor chips, they only sell their microarchitecture designs to different parties.
From Google, Samsung, to Qualcomm, Apple… all have to buy design rights from ARM and every product they make must pay royalties to ARM. That, a lot of you mistakenly think that ARM is a chip manufacturing unit, not you guys.
#2. Why are ARM chips suitable for mobile devices?
The original ARM architecture was based on a RISC architecture, which is considered a computer architecture with more simplified instruction sets.
It is simpler not only in terms of instruction set but also in design, number of transistors per microprocessor. This helps save costs, save energy consumption, but still ensure performance at a relative level.
Simply put, if RISC is a seed, then ARM is a complete tree that keeps growing every day.
With mobile devices or small-sized devices, what any technology company wants to design a microprocessor for them is most interested in is compactness, power saving and above all, ensure acceptable performance. And that’s what ARM architecture owns!
#3. ARM isn’t just on mobile devices
Referring to ARM, people will immediately think of Qualcomm with Snapdragon, Apple with Apple M series chip or Mediatek with Helio or Dimensity….
But that’s not all, actually ARM architecture has appeared in many places, many devices that you don’t notice. With different purposes and uses, ARM Holding named them.
- Cortex A: This architecture is no longer strange, is it, it is the most important thing of Snapdragon, of Dimensity, of today’s leading smartphone devices.
- Cortex US also known as Cosmos, is a microarchitecture designed on devices with high requirements for processing speed and response speed, but must be very small. They are used on car brake sensor systems, protection systems or digital cameras.
- Ethos N: To meet the job WHO growing, ARM also develops this architecture for machine learning tasks, devices that require AI (artificial intelligence).
- Neoverse is a microarchitecture designed for large servers, handling huge data sources but needing power saving and high durability.
- Securcore Designed specifically for Smart Cards.
#4. ARM will grow even stronger
Since Apple cooperated with ARM to successfully launch the chip Apple M1 The whole technology world has wobbled and indeed the day when devices like Laptops and PCs can use this microarchitecture has come.
What was previously considered impossible! Because many companies have tried before and failed as a result, in the end still have to stick with Intel or AMD chips.
The compatibility and stability at the present time of ARM compared to the x86 architecture is somewhat inferior, but it is certainly a game changer. Things are very bright with ARM, not only Apple, now Google, Nvida, Microsoft are also starting to have their plans with ARM already.
If the x86 architecture is said to be revolutionary for PCs with high-performance computers, used for work and large entertainment, ARM is for small basic devices. But with the current development, ARM will soon erase this boundary or at least get closer to x86.
This not only benefits the business of technology companies, but us users also benefit a lot.
Imagine your work-from-home PC now doesn’t have to be big and bulky, but simply a pretty little box with outstanding power. Isn’t that great ^^ !
