​​​​​​​​​​​​​​MMS3120/022-000处理器是解释并执行指令的功能部件。每个处理器都有一个独特的诸如ADD、STORE或LOAD这样的操作集，这个操作集就是该处理器的指令系统。计算机系统设计者习惯将计算机称为机器，所以该指令系统有时也称作机器指令系统，而书写它们的二进制语言叫做机器语言。注意，不要将处理器的指令系统与BASIC或PASCAL这样的程序设计语言中的指令相混淆。
指令由操作码和操作数组成，操作码指明要完成的操作功能，而操作数则表示操作的对象。例如，一条指令要完成两数相加的操作，它就必须知道：(1)这两个数是什么?(2)这两个数在哪儿?当这两个数存储在计算机内存中时，则应有指明其位置的地址，所以如果操作数表示的是计算机内存中的数据，则该操作数叫做地址。处理器的工作就是从存储器中找到指令和操作数，并执行每个操作，完成这些工作后就通知存储器送来下一条指令。
处理器以惊人的速度一遍又一遍地重复以上这一步步的操作。一个称作时钟的计时器准确地发出定时电信号，该信号为处理器工作提供有规律的脉冲。测量计算机速度的术语引自电子工程领域，称作兆赫(MHz)，兆赫意指每秒百万个周期。例如，普通时钟每秒一个滴答，而在8MHz的处理器中，计算机的时钟则滴答了8百万次。
处理器由两个功能部件(控制部件和算逻部件)和一组称作寄存器的特殊工作空间组成。
.控制部件
控制部件是负责监督整个计算机系统操作的功能部件。有些方面它类似于智能电话交换机，因为它将计算机系统的各功能部件连结起来，并根据当前执行程序的需要控制每个部件完成操作。
控制部件从存储器中取出指令，并确定其类型或对之进行译码，然后将每条指令分解成一系列简单的、很小的步骤或动作。这样，就可控制整个计算机系统一步一步地操作。
.算逻部件
​​​​​​​​​​​​​​MMS3120/022-000算逻部件(ALU)是为计算机提供逻辑及计算能力的功能部件。控制部件将数据送到算逻部件中，然后由算逻部件完成执行指令所需的算术或逻辑操作。
算术操作包括加、减、乘、除。逻辑操作完成比较，并根据结果选择操作，例如，比较两个数是否相等，如果相等，则继续处理;如果不等，则停止处理。
.寄存器
寄存器是处理器内部的存储单元。控制部件中的寄存器用来跟踪正在运行的程序的总体状态，它存储如像当前指令、下一条将执行指令的地址以及当前指令的操作数这样一些信息。在算逻部件中，寄存器存放要进行加、减、乘、除及比较的数据项，而其它寄存器则存放算术及逻辑操作的结果。
影响处理器速度和性能的一个重要因素是寄存器的大小。字的大小这一术语(也称字长)描述了操作数寄存器的大小，但它也可用来不那么严格地描述出入处理器的通道的大小。现在，通用计算机的字长通常是8到64位。如果处理器的操作数寄存器是16位的，那么就称该处理器是16位处理器。
2.指令码
数字计算机是通用的数字系统。一台通用数字计算机可执行各种微操作，并且还可以规定它必须执行哪些特定的操作序列。该系统的用户可通过程序控制处理过程，所谓程序是指定操作、操作码及执行处理序列的指令集合。通过编写不同指令的新程序或者对相同指令输入不同数据，可以很简单地改变数据处理的任务。计算机的指令是指定计算机微操作序列的二进制代码。指令码同数据一起存储在存储器中。控制器从存储器中读出每条指令，并将其存放在控制寄存器中，然后控制器解释取出指令的二进制代码，并通过发出一系列控制操作来完成该指令。每台通用计算机都有其的指令系统。存储并执行指令的能力(存储程序的概念)是通用计算机重要的特性。
处理器：处理器（Center Processing Unit，简称CPU）是手机的核心部件，手机中的微处理器类似计算机中的中央处理器(CPU)，它是整台手机的控制中枢系统，也是逻辑部分的控制核心。微处理器通过运行存储器内的软件及调用存储器内的数据库，达到对手机整体监控的目的。凡是要处理的数据都要经过CPU来完成，手机各个部分管理等都离不开微处理器这个司令部的统一、协调指挥。随着集成电路生产技术及工艺水平的不断提高，手机中微处理器的功能越来越强大，如在微处理器中集成先进的数字信号处理器(DSP)等。处理器的性能决定了整部手机的性能。
主频：处理器主频是衡量手机CPU性能高低的一个重要技术参数，几乎所有的人在选购时都将它作为一个参考值。“工作频率”又称为“主频”，频率越高，表明指令的执行速度越快，指令的执行时间也就越短，对信息的处理能力与效率就高。这里要对初学者说的是，处理器的工作频率并不能完全决定其工作性能，设计方法、运行环境等这些都是性能好坏的重要因素。目前现在主流手机上使用的CPU主频有104MHz、160MHZ、200MHZ、220MHz以及400MHz不等。
​​​​​​​​​​​​​​MMS3120/022-000中央处理器，或简称为处理器，英文缩写为CPU，即Central Processing Unit，是电子计算机(港译-电子计算器)的主要设备之一，其功能主要是解译计算机指令以及处理计算机软件中的数据。CPU为电子计算机设计提供了基本的数字计算特性。CPU、存储设备和输入/输出设备是现代微型电脑的三大核心部件。由集成电路制造的CPU通常称为微型处理器。从20世纪70年代中期开始，单芯片微型处理器几乎取代了所有其他类型的CPU，今天CPU这个术语几乎成为了所有微型处理器的代称。
“中央处理器”这个名称，常规上来讲，用来描述一系列可以执行复杂的电脑程序的逻辑机械。这个空泛的定义很容易的将在“CPU”这个名称被普遍使用之前的早期的计算机也包括在内。无论如何，至少从20世纪60年代早期开始(Weik 1961)，这个名称及其缩写已开始在电子计算机产业中得到广泛应用。尽管与早期相比，“中央处理器”在物理形态，设计制造和具体任务的执行上有了戏剧化的发展，但是其基本的操作原理一直没有改变。
早期的中央处理器通常是为大型及特定应用的计算机(港译-电子计算机)而订制。但是，这种昂贵为特定应用定制CPU的方法很大程度上已经让位于开发便宜、标准化、适用于一个或多个目的的处理器类。这个标准化趋势始于由单个晶体管组成的大型机和微机年代，随着集成电路(英文integrated circuit（IC）的出现而加速。IC使得更为复杂的CPU可以在很小的空间中设计和制造（在微米的量级）。CPU的标准化和小型化都使得这一类数字设备(港译-电子零件)在现代生活中的出现频率远远超过有限应用专用的计算机。现代微处理器出现在包括从汽车到手机到儿童玩具在内的各种物品中。
CPU的组成
运算器：算数、逻辑(部件:算数逻辑单元、累加器、暂存器组、路径转换器、数据总线)
控制器：复位、使能(部件:计数器、指令暂存器、指令解码器、状态暂存器、时序产生器、微操作信号发生器)
A processor is a functional unit that interprets and executes instructions.Each processor has a unique set of operations such as ADD,STORE,or LOAD,which is the instruction system of that processor.Computer system designers are accustomed to referring to computers as machines,so this instruction system is sometimes referred to as a machine instruction system,and the binary language in which they are written is called machine language.Be careful not to confuse the instruction system of the processor with instructions in advanced programming languages such as BASIC or PASCAL.
Instructions consist of opcodes and operands,which indicate the operational function to be completed,while operands represent the object of the operation.For example,to complete the operation of adding two numbers,an instruction must know:(1)What are these two numbers?(2)Where are these two numbers?When these two numbers are stored in computer memory,there should be an address indicating their location.Therefore,if the operand represents data in computer memory,the operand is called an address.The job of a processor is to find instructions and operands from memory,execute each operation,and after completing these tasks,notify the memory to send the next instruction.
The processor repeats the above step by step operation with astonishing speed over and over again.A timer called a clock accurately emits timing electrical signals,which provide regular pulses for processor operation.The term for measuring computer speed comes from the field of electronic engineering and is called megahertz(MHz),which refers to millions of cycles per second.For example,a regular clock ticks once per second,while in an 8MHz processor,the computer clock ticks 8 million times.
A processor consists of two functional components(control component and logic component)and a special workspace called a register.
Control components
The control component is a functional component responsible for supervising the operation of the entire computer system.In some aspects,it is similar to a smart phone switch because it connects various functional components of a computer system and controls each component to complete operations according to the current execution needs of the program.
The control component retrieves instructions from memory,determines their type or decodes them,and then decomposes each instruction into a series of simple,small steps or actions.In this way,the entire computer system can be controlled to operate step by step.
Arithmetic components
Logic Unit(ALU)is a functional unit that provides logic and computing power to a computer.The control component sends data to the arithmetic logic component,which then performs the arithmetic or logical operations required to execute instructions.
Arithmetic operations include addition,subtraction,multiplication,and division.The logical operation completes the comparison and selects the operation based on the results,for example,comparing whether two numbers are equal.If they are equal,continue processing;If not,stop processing.
Registers
Registers are internal storage units within a processor.The register in the control component is used to track the overall state of the running program,storing information such as the current instruction,the address of the next instruction to be executed,and the operand of the current instruction.In arithmetic logic components,registers store data items for addition,subtraction,multiplication,division,and comparison,while other registers store the results of arithmetic and logic operations.
An important factor affecting processor speed and performance is the size of registers.The term word size(also known as word length)describes the size of the operand register,but it can also be used to loosely describe the size of the channels entering and exiting the processor.Nowadays,the word length of general-purpose computers is usually 8 to 64 bits.If the operand register of a processor is 16 bits,then the processor is called a 16 bit processor.
2.Instruction code
A digital computer is a universal digital system.A general-purpose digital computer can perform various micro operations and can also specify which specific sequence of operations it must perform.The user of this system can control the processing process through a program,which is a set of instructions specifying operations,opcodes,and execution processing sequences.By writing new programs with different instructions or inputting different data for the same instruction,the task of data processing can be easily changed.Computer instructions are binary code that specifies the sequence of computer micro operations.The instruction code is stored in memory along with the data.The controller reads each instruction from the memory and stores it in the control register.Then the controller interprets the binary code of the instruction and completes the instruction by issuing a series of control operations.Each general-purpose computer has its own unique instruction system.The ability to store and execute instructions(the concept of stored programs)is the most important characteristic of general-purpose computers.
Processor:The Center Processing Unit(CPU)is the core component of a mobile phone,and the microprocessor in the phone is similar to the central processing unit(CPU)in a computer.It is the control center system of the entire phone and also the control core of the logical part.The microprocessor achieves the overall monitoring of mobile phones by running software in the memory and calling databases in the memory.All data to be processed must be completed through the CPU,and the management of various parts of mobile phones cannot be separated from the unified and coordinated command of the microprocessor as the command center.With the continuous improvement of integrated circuit production technology and process level,the functions of microprocessors in mobile phones are becoming increasingly powerful,such as integrating advanced digital signal processors(DSP)into microprocessors.The performance of the processor determines the performance of the entire phone.
Main frequency:The processor main frequency is an important technical parameter that measures the performance of mobile phone CPUs,and almost everyone uses it as a reference value when making purchases.The"working frequency",also known as the"main frequency",indicates that the higher the frequency,the faster the execution speed of instructions,the shorter the execution time of instructions,and the higher the processing ability and efficiency of information.It should be noted to beginners that the operating frequency of a processor cannot completely determine its performance,and design methods,operating environment,and other factors are important factors for good or bad performance.Currently,the CPU main frequencies used on mainstream mobile phones range from 104MHz,160MHz,200MHz,220MHz,and 400MHz.

The Central Processing Unit(CPU),also known as the Central Processing Unit,is one of the main devices in electronic computers(Hong Kong electronic calculators).Its main function is to interpret computer instructions and process data in computer software.The CPU provides basic digital computing features for electronic computer design.CPU,storage device,and input/output device are the three core components of modern microcomputers.CPUs manufactured by integrated circuits are commonly referred to as microprocessors.Since the mid-1970s,single chip microprocessors have replaced almost all other types of CPUs,and today the term CPU has become synonymous with almost all microprocessors.
The name"central processing unit"is generally used to describe a series of logical machines that can execute complex computer programs.This vague definition easily includes early computers before the name"CPU"was widely used.Anyway,at least since the early 1960s(Weik 1961),this name and its abbreviation have been widely used in the electronic computer industry.Although there have been dramatic developments in the physical form,design,manufacturing,and execution of specific tasks of"central processing units"compared to earlier times,their basic operating principles have not changed.
Early central processing units were usually customized for large and specific application computers(Hong Kong electronic computers).However,this expensive method of customizing CPUs for specific applications has largely given way to developing processor classes that are cheap,standardized,and suitable for one or more purposes.This standardization trend began in the era of mainframes and microcomputers composed of individual transistors,and accelerated with the emergence of integrated circuits(ICs).IC enables more complex CPUs to be designed and manufactured in a very small space(at the micron level).The standardization and miniaturization of CPUs have made this type of digital device(electronic components)appear much more frequently in modern life than limited application specific computers.Modern microprocessors appear in various items,from cars to mobile phones to children's toys.
Composition of CPU
Arithmetic:arithmetic,logic(components:arithmetic logic unit,accumulator,temporary storage group,path converter,data bus)
Controller:reset,enable(components:counter,instruction register,instruction decoder,state register,timing generator,micro operation signal generator)
