The arm of the mobile phone processor, what kind of processor is arm?

The mobile phone is an ARM platform, and the exe is compiled from the x86 platform, and there is no way to run it directly; If you have to run, you can only install itVirtual machines, but you can't stand the efficiency guarantee card for three minutes.

ARM architecture.

It used to be called the Advanced Reduced Instruction Set.

The Advanced RISC Machine, formerly known as the Acorn RISC Machine, is a 32-bit RISC processor architecture. There are also derivatives based on ARM designs, notably Marvell's XBontar architecture and Texas Instruments.

OMAP series.

The ARM family accounts for 75% of all 32-bit embedded processors, making it the largest 32-bit architecture in the world. ARM processors.

It is widely used in embedded system design, low power consumption and energy saving, and is very suitable for mobile communications. Consumer electronics, such as portable devices (PDAs, mobile**, multi-devices, handheld video games).

and computers), computer peripherals (hard drives, desktop routers).

x86 Architecture History:

The x86 architecture was introduced in 1978 with the introduction of the Intel 8086

**First in the processor, it is developed from the Intel 8008 processor, which in turn is developed from the Intel 4004. The 8086 was chosen by IBM PCs three years later, after which the x86 became the personal computer.

The standard platform has become the most successful CPU architecture in history.

Other companies also manufacture x86-based processors, including Cyrix (now acquired by VIA), NEC Group, IBM, IDT, and the most successful manufacturer outside of AMD, which has market share in the Athlon series of processors.

Second only to Intel Pentium.

The 8086 is a 16-bit processor; Until 1985, when the 32-bit 80386 was developed, this architecture remained at 16-bit. A series of processors then represented minor improvements to the 32-bit architecture, with several extensions until 2003, when AMD developed a 64-bit expansion of the architecture and named it AMD 64.

Later Intel also launched a processor compatible with it and named it Intel 64. The two are generally referred to collectively as x86-64 or x64, ushering in the 64-bit era of x86.

It is worth noting that Intel cooperated with HP as early as the 1990s to propose a stand-alone 64-bit architecture for use in the Itanium series of processors, which is called a new system and has no resemblance to the x86 architecture at all; It should not be confused with x86-64 or x64.

The ARM processor is the first RISC microprocessor designed for the low-budget market by Acorn Computer. Earlier known as the Acorn RISC processor, the processor itself was a 32-bit design, but it also comes with a 16-bit instruction set, which is generally up to 35% less than the equivalent 32-bit**, but retains all the benefits of a 32-bit system.

The three major characteristics of ARM processors are: low power consumption, strong functions, 16-bit 32-bit dual instruction set, and many partners.

1. Small size, low power consumption, low cost and high performance;

2. Support thumb (16-bit) ARM (32-bit) dual instruction set, which can be well compatible with 8-bit and 16-bit devices;

3. A large number of registers are used, and the instruction execution speed is faster;

4. Most data operations are done in registers;

5. The addressing method is flexible and simple, and the execution efficiency is high;

6. The length of the instruction is fixed.

ARM is a computer processor manufacturer, second only to Intel. It has nothing to do with Qualcomm.

Let's talk about the relationship between Qualcomm and ARM first. ARM itself is not involved in the manufacture and sale of terminal processor chips, but obtains revenue by licensing design solutions to other chip manufacturers.

It's like Google's Android system, which is licensed to mobile phone manufacturers to charge a fee.

ARM offers two types of CPU licensing: core instruction set licensing, and off-the-shelf CPU core design licensing. Most mobile phone processor manufacturers in the industry choose to directly purchase the ARM CPU design solution, and then integrate it with other components (such as GPU, multi-processor, modem, etc.) to create a complete SoC system-on-chip.

These off-the-shelf CPUs are based on Arm Cortex A5, A8, A9, and even A15 microarchitectures. Or based on the existing architecture for secondary customization, such as Samsung's hummingbird core, etc., are modified on the basis of Cortex-A8.

However, there are also a few mobile phone processor manufacturers, such as Qualcomm, which directly develop their own processor microarchitectures based on the ARM V7 instruction set, such as Qualcomm's Scorpion and Krait, and then design their own CPUs with greater flexibility.

ARM is an architecture of a processor.

First of all, ARM is not a processor but a processor architecture design company, not a processor production company, and ARM has a lot of series of processor design architectures, similar to Crotex (currently no processor manufacturing companies with their own architecture use Arm's public architecture Crotex series in terms of mobile phone processors), this series is just an important branch of his series. First, because the processor is a very complex object, in addition to the architecture, the processor has many related things, such as a good processor must also have a higher frequency (that is, the frequency of the processor, the higher the frequency, the faster the processor will operate), and the process (this is related to the power consumption problem, the smaller the process, the better the power consumption), so a good processor needs to be appropriate in the three main aspects of the main frequency, architecture, and process, of course, there are other details. If ARM wants to produce processors, there must be a production line, but the process is also a thing that requires a high level of technology, and the best in the world is currently two TSMC (Taiwan company) and Samsung (South Korean company), which is also a very troublesome thing, but ARM's current profit model by selling processors and other designs is also a very novel, very suitable model for its own model, so it does not need to produce processors at all, and it is also possible to sell design patents closely. Of course, complexity is also an aspect.

The ARM Crotex series is also known as the public architecture, which can be bought for money if you need it (like Qualcomm also has its own processor architecture, which is currently used on its own processors and is not licensed for export, of course, he also uses the ARM architecture at times). The previous main frequency process architecture is mutually influential, and the process and the main frequency are mutually restrictive (power consumption determines the amount of heat generated, and the system will reduce the main frequency accordingly when the heat is too large). Of course, the smaller the process, the better, in the case of a similar number of nanometers in the process, the maturity of the technology is also an aspect to consider, for example, TSMC's 16nm is slightly better than Samsung's 14nm.

In your question, you said that Qualcomm's processor is better to play large games, because Qualcomm has its own special architecture in GPU (graphics mapping technology), GPU you can understand it as a computer graphics card, mobile phones because of space problems, will not have a separate graphics card like a computer, basically attached to the CPU. MediaTek or Huawei do not have their own GPU architecture, and both use the public version of the GPU architecture, which is a hierarchical problem of technology. Moreover, Qualcomm's GPU will be stronger than the public version of the architecture (optimization and design problems), and it also has a certain relationship with the CPU.

In general, it is a question of whether the technical background has reached or not.

The A-series processors used in Apple's mobile phones are developed by themselves and use the ARM architecture.

Apple's computer products have been fully equipped with Intel processors since 2006, but iOS mobile devices such as iPad and iPhone use Apple's self-designed A-series ARM SoC processors (such as iPhone XS, iPhone XR, iPhone 8, etc.).

The processor used by the iPhone is not compatible with the X86 or PowerPC processors used by the Mac OS, and third-party applications used to run in a controlled environment through Safari.

[A] :p the OferMac period, the CPU of the Mac was introduced from IBM, and the current Mac has been fully replaced with Intel chips, and the hardware architecture is no different from everyone's ordinary X86 PC.

**Processor:(CPU, Central Processing Unit) is a very large-scale integrated circuit, which is the computing core and control core of a computer. Its function is mainly to interpret computer instructions as well as process data in computer software.

Key Features]:

processing instructions; This refers to the order in which instructions are executed in the control program. There is a strict order between the instructions in the program, and it must be executed strictly in the order specified in the program in order to ensure the correctness of the computer system.

Perform an action; The function of a single instruction is often achieved by a series of operations performed by a component in the computer. According to the function of the instruction, the CPU should generate the corresponding operation control signal and send it to the corresponding components, so as to control these components to act according to the requirements of the instruction.

control time, English control time; Time control is the implementation of time timing for various operations. During the execution of an instruction, what actions should be done at what time and in a matter of strict control. Only then will the computer work in an orderly manner.

Processing data, i.e., performing arithmetic and logical operations on data, or other information processing.

ARM architecture. Formerly known as the Advanced RISC Machine (earlier known as the Acorn RISC Machine), it is a 32-bit RISC processor architecture that is widely used in many embedded system designs.

Due to their energy efficiency, ARM processors are ideally suited for use in the field of mobile communications, where they are designed to consume less power.

Apple is the co-founder of AMR, and you are still sleepwalking through this?

ARM license, based on ARM transformation and development.

The strength of Arm's business model lies in the fact that it has more than 100 partners around the world. ARM uses a transfer license system, and the chips are produced by partners.

The ARM platform is derived from the microcontroller, and like the microcontroller, ARM is also a multi-interface processor system, however, ARM has been upgraded from an 8-bit microcontroller to a 16-bit or even 32-bit microcontroller, which can be considered a CPU. Strictly speaking, ARM chips not only have the addressing and computing functions of the CPU, but also add a lot of external interfaces, such as serial ports, mid-range control ports, etc. In order to realize a complete set of computer functions, but this function is not as comprehensive as the computer, but the integration is high, the pertinence is strong, and it is the best choice for embedded equipment computing hosts.

The most representative chipset is the A4 and so on that Apple devices now use.
