ARM processors: architectural features, features and prospects. How to identify which processor on Android A short excursion into history

ARM and x86 are two of the most advanced processor architectures on the planet. What are their strengths and weaknesses for productivity and energy efficiency?

For many years, ARM (first Acorn RISC Machines, now Advanced RISC Machines) has been at the center of modern microprocessors and inspired design. By focusing on energy efficiency and a simple set of instructions, mobile video devices have benefited greatly from processor design. This allowed us to rapidly accelerate the development of the mobile market.

It's a shame that the Raspberry Pi debuted, having taken over the Broadcom SoC, which included an ARM core clock frequency 700 MHz. The ARM core itself boasted low performance and simplicity.

On its side, Intel mainly produced processors with high productivity and high access control including desktop PCs, laptops, servers and supercomputers. But this is no longer the case, as Intel is seizing the market of mobile/light-weight computers with a wide variety of mobile processors, including Intel series Atom (one of the main processors that powers Windows 10 tablets).

The two families of processors have a lot of features, including their performance, energy efficiency, software and software. Let's take a look at how the ARM architecture differs from the x86 more clearly.

After reading it, you will clearly understand what we have already written: . Very interesting information for those who have flash drive However, they are all clogged with important files.

Difficulty in the labor of labor

ARM processors fit into the RISC family, which means “Shorter instruction set”.

The RISC processor focuses on saving as many instructions as possible, while simultaneously saving instructions as simple as possible. Simple instructions can help both engineers and software developers. While the instructions are simple, the required circuitry requires fewer transistors to drive more chips and/or smaller chips. Through ARM processors, as a rule, there is a lot of peripheral devices Including graphics processors that enable computers such as the Raspberry Pi, with so few components.

Even simple instructions are expensive. To begin writing, provide the necessary additional instructions to increase your memory and time of writing. Timing is no less, the ARM processor compensates for the increased time it takes to compete with larger faster processors and a handset.

On the other hand, Intel processors fit into the CISC family, as a complex Set Computing command.

For RISC computers, the instructions available on CISC are more focused on various folding tasks with great flexibility.

For example, many RISC-based machines store register operations that require the program to store the registers before performing the operation. However, a CISC-based machine can (or is capable of) concatenating operations between registers, between a register and a memory space, and transferring between memory stores. Other advanced operations include floating number multiplication, drill rolls, single instruction loops, complex memory manipulation, memory searches, and much more. This is part of how the ARM architecture evolves from x86. Prodovjimo.

Exhaustion while experiencing fatigue

The tightness of the constructed structures may be one of the most important criteria. A system that is designed to be connected to a power source, such as electrical power supply, can therefore ignore the loss of accumulated energy, otherwise mobile design(or one, connections to an unreliable life device) may be completely neglected in the management of life.

ARM parts replace solid structures with a large number of their cores (or more), which require heatsinks. Their typical energy consumption does not exceed 5 W with many packages, including graphics processors, peripheral devices and memory. Such a low voltage is only possible through a smaller number of high-quality transistors and rather low voltages (alternatively). desktop processors). But again (which is the problem with the front section), this affects the productivity of the system, and complex operations take more than an hour.

Through their advanced foldability Intel cores have more energy than ARM cores. The high-performance Intel I-7 can handle up to 130 W of power, while Intel mobile processors (such as Atom and Celeron) can handle 6 W to 30 W. Processors with the lowest pressure (Atom line), intended for use with laptops, do not integrate graphics into the processor, but mobile versions do. However, those that integrate graphics run at significantly lower clock speeds (from 300 to 600 MHz MHz), which results in lower throughput.

Features of the software


When there are two big names on the processor market, equalizing the availability of software and toolkits is difficult, as they are even more popular. An ARM-based device has an advantage in working with operating systems designed for mobile phones, such as Android. Intel devices have the advantage of being able to run virtually any operating system that can run on a standard desktop PC, including Windows and Linux. Devices can run the same programs, as long as the program is compiled in mov or vikorist virtual machine for example Java.

If we talk about those in which the ARM architecture evolves from x86, then we can say with success that the main focus is on productivity and focus on different types of add-ons. Main task ARM processors - energy management for greater efficiency mobile devices Oh. And the manager desktop versionsє greater productivity.

Processor (CPU) is the main component of any computer, mobile phone or other smart gadget. The processor itself accounts for the majority of all calculations required for the device, operating system and accessories. Therefore, productivity flows into the productivity of the entire structure. If the processor does not work well enough, the system suffers from freezes, excessive launch of applications, and lags in the robot interface.

Considering everything described above, it’s not surprising that so many koristuvachs crow about the installation processor on their device. This instruction will show you a number of ways to retrieve this information and find out which processor is installed on your Android phone.

To find out which processor is installed on Android phones, as well as look at its other characteristics, you need to install special supplement.

In 2011, ARM Limited announced a new family of processors called ARMv8. And in 2013, Apple released its first ARMv8 processor - the A7 single-chip system, which is found in the iPhone 5S, iPad Airі iPad mini Retina. The ARMv8 architecture adopted a 64-bit instruction set, but this is far from being an advantage over its predecessor ARMv7. How 64-bit ARMv8 processors are controlled, read the statistics.

You can read about the history of ARM architecture, the specifics of the activities of ARM Limited and the generation of ARMv5, ARMv6 and ARMv7 processors in the article. And about popular models of ARMv7 chips produced by Qualcomm, NVIDIA, Samsung, Apple, MediaTek, etc.

The updated architecture of ARMv8 family processors was named AArch64. It took advantage of the 64-bit instruction set and the ability to work with a large amount of RAM (4 GB or more). Of course, the amount was transferred from 32-bit add-ons (AArch32). Other important innovations of ARMv8 were:

- 31 registers zagalnogo significance, each with a maximum of 64 bits, so both SP and PC do not have registers with special purpose. What is the size of the registers? more number You can save money from them. And the greater the number of registers, the more data they hold at one time. As a result, a larger amount of data can be processed in one instruction, and the entire algorithm is completed faster;
- translation of virtual addresses from a 48-bit format uses additional LPAE mechanisms found in ARMv7;
new dial Instructions from a fixed date. Instructions are 32 bits in size and many people use AArch32 commands, although there are fewer mental instructions;
— the number of 128-bit registers available to SIMD NEON and VFP processors has been increased from 16 to 32, and a new one has also been added Cryptographic instructions AES and SHA. Setting the SIMD NEON instruction speeds up the work of programs that are responsible for processing media and signals. In its own way, VFP stands for low-energy calculations over numbers with a floating coma;
- Support for calculating numbers with a floating point of high precision according to the IEEE 754 standard, which is the standard format for representing numbers with a floating point, which is used in software implementations of arithmetic operations.

Reference cores ARM Limited

The first ARMv8 processor cores, developed directly by ARM Limited, were Cortex-A53 and A57. The A53 core is a mid-range solution with a performance of 2.3 DMIPS/MHz, which is approximately in the middle between the low-end Cortex-A7 (1.9 DMIPS/MHz) and A9 (2.5 DMIPS/MHz). While the A57 occupies the upper segment, even its speed code (4.1 DMIPS/MHz) exceeds the performance of both 32-bit flagships: Cortex-A15 (3.5 DMIPS/MHz) and A17 (4 DMIPS/MHz).

In addition to licensing reference processor cores, ARM Limited sells license extensions that allow chip makers to modify the ARM architecture at their discretion. Such licenses include, for example, Apple, Qualcomm and NVIDIA. Therefore, there is no need for processor developers to create solutions based on ARMv8, which are completely different from the reference Cortex-A53 and A57.


Apple A7

The first and so far the only 64-bit ARM processor that is already found in smartphones and tablets is the Apple A7. Prompts on the proprietary architecture of Apple Cyclone, combined with ARMv8. This other processor architecture has been fragmented in the middle of the company; The first one was Swift (A6 and A6X chips, ARMv7 family).

The single-chip A7 system has only two processor cores (frequency up to 1.4 GHz), and there is also a graphics processor PowerVR G6430 with several clusters of cores. The speed of the A7 chip in processor-intensive tasks increased approximately twice as much as in the A6, while in various graphics tests the increase became two to three times.

And the theoretical ability to work with the large amount of RAM of the 64-bit architecture of the A7 processor installed under iOS devices is not yet understood. The iPhone 5s, iPad Air and iPad mini Retina all have less than 1 GB of RAM; and unlikely for the new generation of mobile phones Apple devices obsyag OZP vyroste bolshe nezh udvich.

Qualcomm Snapdragon 410, 610, 615, 808 and 810

After Apple, Qualcomm hastened to announce its 64-bit ARM processors, including five models. It’s true that commercial smartphones and tablets still don’t have enough of them. Best of all, the availability of 64-bit Android devices will begin in 2015 at the CES and MWC exhibitions.

The single-chip system Snapdragon 410 (MSM8916) is the latest from the announced 64-bit line from Qualcomm. It includes Cortex-A53 cores with a frequency of 1.2 GHz, an Adreno 306 graphics processor and, most importantly, a navigation module with satellite tracking GPS, GLONASS and Chinese navigation. Zastosovuvati Snapdragon 410 is planned inexpensive smartphones based on Android, Windows Phone that Firefox OS.

The same Cortex-A53 cores as the 410 have a Snapdragon 610 chip (MSM8936), only the graphics axis of this one has an Adreno 405. Same as the Snapdragon 615 (MSM8939) similar to the 610 graphics, but also cerebral kernels A53 new twice more – all Cortex-A53.

In addition to 410, 610, 615 models, based on the 28-nm process technology, Snapdragon 808 (MSM8992) and 810 (MSM8994) chips will be based on the advanced 20-nm technology standards. I'll be offended by the big.LITTLE scheme: two (model 808) or two (810) heavy-duty Cortex-A57 cores and two energy-efficient Cortex-A53 cores. The graphics are presented by Adreno 418 and Adreno 430 consistently. In addition, the older Snapdragon 810 may use a RAM controller based on the LPDDR4 standard.

Alas, a headache: if Qualcomm presented a powerful processor architecture based on ARMv8, what would happen with Scorpion and Krait (modified ARMv7)?

MediaTek MT6732, MT6752, MT6795

The MediaTek company could not be deprived of 64-bit transmissions for long, as it quickly transformed from a small processor processor for Chinese iPhone clones into one of the largest chipmakers in the world, even without a factory. However, Apple and Qualcomm have no control over their power.

Single-chip systems MediaTek MT6732 and MT6752 are subject to competition with Snapdragon 610 and 615 chips. They have both the same Cortex-A53 processor cores (frequency 1.5 and 2 GHz simultaneously) and the same Mali-T760 graphics ( distribution ARM Limited). The older MT6795 chip is based on the Snapdragon 810: big.LITTLE architecture, including Cortex-A57 and A53 cores with a frequency of 2.2 GHz, as well as the graphics processor PowerVR G6200.

NVIDIA Tegra K1 (Project Denver)

NVIDIA has decided to switch its existing Tegra K1 chip to a 64-bit processor architecture. The graphics capabilities of the new one were not the best among its competitors - GK20A with 192 Kepler cores, 365 GFLOPS productivity and support for PC graphics standards DirectX 11.2 and OpenGL 4.4 (and not their mobile counterparts iv).

Instead of four 32-bit Cortex-A15 cores (plus an energy-efficient core), the updated Tegra K1 single-chip system includes two ARMv8 cores of the NVIDIA Project Denver proprietary architecture. The processor clock speed increases to 2.5 GHz, and the cache capacity increases. Cool fact: Tegra K1 graphics are about fifty times faster than Tegra 2

Visnovki

In one clock cycle, the ARMv8 architecture processor processes significantly more data. This determines both the overall productivity of the processor and the productivity of the processor. Vakhovuyuchi exchange of technological standards (maximum permissible clock frequency), the transition to ARMv8 is one thing possible way build up speed code mobile processors, without going beyond the reasonable limits of energy consumption and heating.

Of course, the cost of the ARMv8 architecture is limited to only those programs for iOS and Android, which use all the resources of the new processors. Optimization of programs for a new architecture can be either manual or automatic, or at the level of a compiler.
The first Android device with a 64-bit ARM processor and 4 GB of RAM - Samsung phablet Galaxy Note 4 ( . And for others, perhaps, tablet computer HTC series.

About the ARM architecture, people who like mobile technologies love it. In this case, most people associate themselves with the processors of tablets and smartphones. Others should correct them, clarifying that it is not the stone itself, but rather the architecture. But practically none of them are exactly right, it’s important to know that this technology has been introduced.

And now the technology has expanded among the number of modern gadgets, which are becoming more and more common with the fate of the skin. In the meantime, the development of the company, which is engaged in the development of ARM processors, is on the way, there is one significant failure that cannot be predicted, perhaps for whom it will become a lesson in May.

ARM architecture for dummies

Under the acronym ARM, the successful British company ARM Limited hopes to continue to operate in the field of IT technologies. Deciphered as Advanced RISC Machines and one of the great light distributors and licensors of the 32-bit architecture of RISC processors, which are equipped with most portable devices.

However, what is typical is that the company itself is not involved in the development of microprocessors, but rather distributes and licenses its technology to other parties. The Zokrema ARM architecture of microcontrollers is purchased by the following manufacturers:

  • Atmel.
  • Cirrus Logic.
  • Intel.
  • Apple.
  • nVidia.
  • HiSilicon.
  • Marvell.
  • Samsung.
  • Qualcomm.
  • Sony Ericsson
  • Texas Instruments.
  • Broadcom.

Their activities are visible to a wide audience of digital gadget users. According to the British corporation ARM, the total number of microprocessors generated by their technology is over 2.5 billion. We start a series of mobile stones:

  • ARM7 – clock frequency 60-72 MHz, which is relevant for budget mobile phones.
  • ARM9/ARM9E - the frequency is already higher, close to 200 MHz. Most functional smartphones and small computers (PDAs) are equipped with such microprocessors.

Cortex and ARM11 are now the most current families of microprocessors that are similar to the previous architecture of ARM microcontrollers, with clock frequencies of up to 1 GHz and expanded capabilities for processing digital signals.

The popular xScale microprocessors from Marvell (until mid-summer 2007, the project was owned by the dismantled Intel) actually have an expanded version of the ARM9 architecture, an additional set of Wireless MMX instructions. Ceremony Intel was aimed directly at supporting multimedia programs.

ARM technology is being upgraded to a 32-bit microprocessor architecture to accommodate a faster set of commands, which is called RISC. According to the renovations, the stagnation of ARM processors is 82% of the total number of recovered RISC processors, which means covering a wide coverage area of ​​32-bit systems.

Many electronic devices are equipped with ARM processor architecture, not just PDAs and Stilnikov's telephones, as well as portable game consoles, calculators, computer peripherals, Merezheve obladnannya and much more.

A little expensive back at the past

It’s broken on the old machine for a few hours and we’ll try to figure out where it all began. We can honestly say that the ARM company is, rather, a monopolist in its own right. And this is confirmed by the fact that the number of smartphones and other electronic devices is important digital devices operate under the control of microprocessors created behind this architecture.

In 1980, the company Acorn Computers was founded and began creating personal computers. Previously, ARM was known as Acorn RISC Machines.

Rik therefore was presented to the court of the companions home version BBC Micro PC with the latest ARM processor architecture. This was a success, but the prote chip could not cope with graphic rooms, And other options such as the name of the Motorola 68000 and National Semiconductor 32016 processors were also suitable.

Then the company's management thought about the development of its microprocessor. The engineers were intrigued by the new processor architecture, which was invented by graduates of the Moscow University. She has a shortcut set of commands, or RISC. And after the appearance of the first computer, which was equipped with the Acorn Risc Machine processor, success began to increase rapidly - in 1990, a contract was signed between the British brand and Apple. This initiated the development of a new chipset, which, in turn, led to the creation of an entire team of developers called Advanced RISC Machines, or ARM.

Beginning in 1998, the company changed its name to ARM Limited. And now the representatives are not engaged in the development and implementation of the ARM architecture. What did it give? The development of the company was not affected at all, although the main and single direction of the company was the development of technology, as well as the sale of licenses to third-party companies, so that they could use the processor architecture. In this case, the company acquires the rights to ready-made kernels, which, with an additional license, equip processors with their own kernels.

Based on the current data on the company's earnings, the decision to make 0.067 $. But this information is average and outdated. The number of cores in chipsets is increasing, and it is likely that the compatibility of current processors is outweighing older processors.

Galuz zastosuvannya

The very development of mobile devices has brought great popularity to ARM Limited. And if the proliferation of smartphones and other portable electronic devices It became widespread, and energy-efficient processors immediately became stagnant. The axis is okay, but why is Linux on arm architecture?

The culminating period of development of the ARM company falls on 2007, when partner networks were renewed. Apple brand. After this, the first iPhone based on an ARM processor was presented to the community. From now on, such a processor architecture has become an indispensable warehouse for almost any smartphone that can only be found on the current mobile market.

We can say that it is practically a daily electronic device that will require control of a processor, otherwise equipped with ARM chips. And the fact is that such a processor architecture supports a variety of operating systems, such as Linux, Android, iOS, and Windows, etc. unprotected advantage. Among them is Windows embedded CE 6.0 Core, the arm architecture is also supported by it. This platform is insured for computer development, mobile phones that system that will be implemented.

Runtime x86 and ARM

There are a lot of people who have heard about ARM and x86, but the two architectures are confused with each other. And at this hour the stench of the songs of humility. There are two main types of architectures:

  • CISC (Complex Instruction Set Computing).
  • Computing).

Before CISC, x86 processors (Intel and AMD) are installed, before RISC, as you can see, the ARM family. The x86 and arm architecture have their own quirks. Thanks to the efforts of ARM representatives, who spoke about energy efficiency and a simple set of instructions, the processors greatly benefited from this - the mobile market began to develop rapidly, and many smartphones almost appreciated the possibilities of computers.

Intel has always been famous for producing processors with high productivity and throughput for desktop PCs, laptops, servers and supercomputers.

These two homelands, in their own way, won the hearts of the Koristuvachs. But what is its importance? There are important signs that indicate the peculiarities of the family, let’s look at the most important ones.

The tightness of the garment

Let’s take a closer look at the capabilities of ARM and x86 architectures from this parameter. The specialty of RISC professors lies in their limited number of instructions. Moreover, the culprits are as simple as possible, which gives them advantages not only to engineers, but also to software developers.

The philosophy here is complicated - since the instructions are simple, the required circuit does not require a very large number of transistors. As a result, additional space is created for which or the dimensions of the chips become smaller. Therefore, ARM microprocessors began to be combined into peripheral devices, similar to graphics processors. An example example is a Raspberry Pi computer, which has a minimal number of components.

The simplicity of the instructions comes at a cost. To cancel these and other tasks, you will need additional instructions to ensure that your memory increases in the time it takes to cancel the task.

In the case of the arm-architecture of the processor, the instructions of CISC chips, as developed by Intel, can be used for complex applications with great flexibility. In other words, RISC-based machines perform operations between registers, and require the program to import the changes into the register before performing the operation. CISC processors are designed to operate in a number of ways:

  • between registers;
  • between the register and the memory place;
  • between memory centers.

Although there are only a few of the important figures, let’s move on to the analysis of other signs.

tension has been relieved

Depending on the type of device, the resulting tension can result in a different level of significance. For this system, which is connected to a constant supply source (electrical power supply), there is simply no exchange of accumulated energy. However, mobile phones are also electronic gadgets The rest of the world will lie under the control of the taverns.

Another advantage of the arm and x86 architecture is that the first power consumption is less than 5 W, including a lot of related packages: graphics processors, peripheral devices, memory. Such low pressure is due to the smaller number of transistors and the remarkably low speeds (as a parallel with processors for desktop PCs). That very hour had a hit on productivity - it took more than an hour to complete complex operations.

Intel cores are distinguished by their foldable structure and through the combined energy of their components. For example, the Intel I-7 processor with high productivity achieves close to 130 W of energy, mobile versions – 6-30 W.

Software security

It is important to check this parameter, as some offensive brandies are even more popular among their colas. Devices that run on arm-architecture processors work wonderfully with mobile operating systems (Android and others).

Machines running Intel processors run on Windows and Linux platforms. Until then, it’s a shame for the family of microprocessors to be friends with add-ons written in my Java.

Analyzing the architecture features, one thing can be said unequivocally: ARM processors are at the forefront of energy-saving mobile devices. The task of desktop solutions is most important in ensuring high productivity.

New achievement

The ARM company has completely taken over the mobile market due to the implementation of competent policies. Ale far away, he is not going to rest on what he has achieved. Recently, a new core design was introduced: Cortex-A53, and Cortex-A57, in which one important update was carried out - an increase in 64-bit computing.

The A53 core is a direct successor of the ARM Cortex-A8, although it does not have very high productivity, but energy consumption is at a minimum level. As they say, the energy consumption of the architecture is reduced by 4 times, and the productivity of the Cortex-A9 core is not compromised. This is despite the fact that the core area of ​​A53 is 40% smaller than that of A9.

The A57 core will replace Cortex-A9 and Cortex-A15. At the same time, ARM engineers claim a phenomenal increase in productivity - compared to the A15 core. In other words, the A57 microprocessor will be 6 times faster than the Cortex-A9, and its energy efficiency will be 5 times higher than that of the A15.

To sum it up, the cortex series, and the perfected A53 itself, stands out from its predecessors in its high productivity on aphids and not less high energy efficiency. Bring in Cortex-A7 processors, which will be installed on most smartphones, without facing competition!

What’s even more valuable is that the architecture of the arm cortex a53 is like a warehouse, which will eliminate problems associated with poor memory. In addition, the device will drain the battery more quickly. These new problems are now lost to the distant past.

Graphic solutions

In addition to developing processors, ARM is working on the Mali series of graphics processors. The first of them is the Mali 55. The LG Renoir phone was equipped with it. And yes, this is a very basic mobile phone. However, in this case, the GPU was not good for games, but rather for the small interface, and judging by current standards, the graphics processor has primitive capabilities.

In order to keep up with the times, ARM has more advanced models that are relevant for smartphones in the mid-price category. We are talking about expanding the GPU Mali-400 MP and Mali-450 MP. Although they have low productivity and dialing APIs, they do not respect the stagnation of current mobile models. The brightest example is the Zopo ZP998 phone, which has an eight-core MTK6592 chip paired with a graphically fast Mali-450 MP4.

Competitiveness

At this time, the ARM company has not yet resisted, and the top rank is based on the fact that the decision was praised at the right time. Once upon a time, a team of developers has been working on the creation of processors for PCs for a long time and tried to compete with such a giant as Intel. However, after the direct line of business was changed, the company had a hard time.

And if the world-famous computer brand Microsoft has entered into an agreement with Intel, the manufacturer simply has a good chance - operation Windows system Was encouraged to work with ARM processors. How can we not get involved with the use of gcam emulators on the arm architecture? Although the Intel company, which praises the success of ARM Limited, has also tried to create a processor that would meet the competition. For this wide range of information, we need an Intel Atom chip. It took a much longer period of time than ARM Limited. And in 2011, the production of new crops has lost its momentum, but a valuable hour has already been wasted.

Essentially, Intel Atom is a CISC processor with x86 architecture. Fakhivtsy managed to achieve lower energy consumption, lower in ARM solutions. Please note that all software that is released for mobile platforms is poorly adapted to x86 architecture.

The company has become increasingly popular decision made It was later inspired by the development of processors under mobile devices. The one great manufacturer of Intel Atom chips is ASUS. At the same time, these processors did not go into oblivion; they were widely used in netbooks, netbooks, and other portable devices.

However, it is clear that the situation will change and the Windows operating system supports ARM microprocessors. Until then, what is the point in asking directly, can we really go to the gcam emulator platform on ARM architecture for mobile solutions?! Who knows, the hour will tell and put everything in place.

In the history of the development of the ARM company, there is one important moment (at the very beginning of the article itself is respected). If ARM Limited was based on the Apple company, it is certain that all ARM technology was based on it. However, the share was disposed of differently - in 1998, Apple was in crisis, and Kerivnitsa was hesitant to sell its share. At this time, she is on par with other producers and is lost to her own iPhone devices and iPad purchase technology from ARM Limited. Who knows how things might turn out?

Today's ARM processors perform complex operations. And in the near future, the company’s core aims to enter the server market, which is, of course, a problem. Until then, as we approach the era of development of the Internet of Things (IoT), among other “reasonable” everyday devices, we can predict an even greater demand for chips with ARM architecture.

Well, ARM Limited has a far from hopeless future ahead of it! And it is unlikely that in the near future we will find someone who can oust this, in any doubt, mobile giant from the development of processors for smartphones and other similar electronic devices.

ARM processors have quickly taken over the market of mobile devices and all due to low energy consumption and not very high, but still good productivity. At this time, the ARM company can help you get a late greeting. There are a lot of manufacturers that are developing these technologies, which puts Advanced RISC Machines on par with such giants in the field of processor development such as Intel and AMD. And this is despite the fact that the company does not have any pollution.

What time is the competitor mobile brand There was a MIPS company with the same architecture. At the moment, the only serious competitor in particular is the Intel corporation, although it does not matter that the arm architecture can pose a threat to its market part.

Also, according to analysts from Intel, ARM processors will not ensure the launch of desktop versions operating systems. However, such a statement sounds very illogical, even though owners of ultra-mobile PCs do not profit from “vagovitim” software security. Most often you need access to the Internet, editing documents, listening to media files (music, movies) and other difficult tasks. And ARM is capable of miraculously coping with such operations.

Singing the skin from you, putting food: what is ARM? You can even often feel this abbreviation if you are talking about a processor device. And in an hour I finally understood its essence.

Let's just say that ARM is the same company, but ARM is another processor architecture, as developed by the ARM company.

An ARM processor is a CPU based on the RISC architecture, developed by the Acorn Computers company in the 1980s, and later developed by the Advanced RISC Machines company, to the point where the abbreviation “ARM” is used. In this case, the abbreviation ARM directly in front of the processor architecture means Acorn RISC Machine. In other words, there are two meanings of the abbreviation ARM.

Advanced RISC Machines is a British-owned company that develops, designs and licenses ARM processor architectures. ARM is unbundling its method of producing ARM processors, and companies such as Apple, Samsung, and Samsung are unbundling their ARM-based processors. Currently, almost all devices that are small in size and equipped with a battery have processors based on ARM architecture.

There are a number of types of processor architecture: CISC, RISC, MISC. First, there is a large set of commands, so CISC is equipped to deal with complex instructions for many years. RISC, however, has a shorter set of commands that use one format and are divided into simple coding.

To understand the difference, realize that your personal computer has an AMD or Intel processor with CISC architecture installed. CISC processors generate more than MIPS (millions of instructions per second, which is the number of instructions generated by the processor per second).

RICS processors use fewer transistors, which allows them to consume less energy. The number of instructions has been changed to allow the design of microcircuits to be simplified. Changing the size of microcircuits leads to a small die size, which allows you to add more components to the processor, keeping ARM processors small and more energy efficient.

The ARM architecture is ideally suited for smartphones that require energy saving, whereby the performance of ARM processors is obviously at the expense of top solutions from Intel and AMD. All things considered, ARM processors cannot be called weak. ARM supports both 32-bit and 64-bit architectures, as well as support for hardware virtualization, allowing for greater control over life.

The main parameter when evaluating ARM processors is the efficiency of combined energy, here ARM processors perform better than, for example, an x86 processor from Intel based on the CISC architecture.

Thus, with supercomputers, we will increasingly add millions of ARM processors instead of thousands of processors on the x86 architecture.
