What is Cpu Processor
Spread the love by share
  • CPU Processor is an electronic piece with millions of transistors in it. Together, the aggregate and the most important unit of components.
  • The computer where it takes all the tasks that the user requires from the computer, where he receives from the user the requested command and executes it.
  • The task of executing this matter, whether it is related to mathematical, logical, or other information so that you can describe it as the brain behind the computer
  • Automated. The processor in the English language is called “CPU” and it is an abbreviation for “Unit Processing Central” which means “unit”.
  • Central Processing. “
  • Computer performance is evaluated from the efficiency of the processor in it. Therefore, we must determine what are the criteria by which we can comply.
  • Know the best processor. These criteria are:
  • 1- Name of the company producing the processor:
  • As there are many companies working in the right to produce processors more than “Intel” and “AMD”
  • CYRIX, RISC, and others.

2- processor performance:

The processor performance power is measured by the number of commands that can be performed per second per unit.

3- processor speed:

There are processors at different speeds like (2000, 2400, 2600, 3000) one million turns per second.
The faster the processor, the higher the number of operations within the computer, per second.

4- Family or processor number:

As each processor has a number or a family that distinguishes it from others.

5-Processor infrastructure :

  • The processors consist of a very large number of transistors, as mentioned above, so what is their work? What is it?
  • The processor deals with the data in the form of “bits”, because the processor only understands a language according to (0.1) and if we look at an in-depth look
  • Inside the therapist, and we looked at what he does, and we find that he either performs mathematical operations such as addition and subtraction and other operations or performs operations.
  • Logic, and in all cases the therapist must make the right decisions and lead the work on this basis, so how does the computer make
  • Decisions?
  • This is the work of transistors, as they are distributed in the form of groups inside the processor so that each group of them makes
  • Specific, for example, one group is specialized in comparison of numbers and the other for making decisions in a specific case and so on. The number varies
  • And the way the transistors collect in each group, which affects its function, and the computer can use these different groups
  • In a thoughtful and organized manner in carrying out the work assigned to it. Each of these groups is called a “logic portal” that varies according to
  • The function they perform and the number of transistors they contain, and if a large number of these gates collect to perform a certain function, they become
  • We call it an “integrated circuit”, and the processor is nothing but a group of integrated circuits that are complexly related to each other.
  • Dear reader, here is a summary of what has been explained:
  • Several transistors = functional group (gate)
  • Several functional gates = integrated circuit
  • Several integrated circuits = processor
  • The transistor itself is a very small unit that allows the passage of electric current through it at a different circuit
  • The current inside it allows to control the intensity of the electric current according to the intensity of the other electrical current, and the use of this small unit
  • (Transistor) We can organize it to form units with a specific function that differ in the order in which they are arranged and coordinated by the transistors.
  • Thus, we can form endless types of units (functional gates, integrated circuits) and the greater the number of transistors that
  • It consists of integrated circuits whenever possible to implement more complex functions.

6- CPU standard:

  1. Inside the processor, there are millions of transistors that are used together with the process of the process and it is not hidden from you that these millions of
  2. The transistors are all placed in a very small area and between one another and a very small area and connected with each other.
  3. Some are quite small in data flow between transistors, and the thickness of these wires is divided into โ€œmicronโ€ units.
  4. It is the thickness of these wires that determine the architecture of the processor, and the smaller the architecture of the processor, the less the energy consumption.
  5. The heat generated by the processor was lower, which reduces the cooling problems, and the smaller architecture enables us to use a lower current voltage.
  6. Pass through these wires.
  7. Micron definition: It is the unit of measurement of length equal to one-millionth of a meter.

7- The main components of the processor:

  • The processor consists of the following main parts:
  • First / Unit Output / Input ๐Ÿ™
  • Controls the flow of data to and from the processor, which is the part that performs data and coordinates with random memory in
  • Data validity. This unit has no impact on the performance of the processor because each processor is equipped with a special unit of input and output suitable for it, and it is also
  • You cannot upgrade or modify this unit but rather an integral part of the CPU itself.
  • One of the reasons why limiting input and output is important is because it contains the cache from the first level.
  • L1Cache (which we will talk about later).
  • Second / Unit Control:
  • The control unit is the mastermind of all parts of the computer so that no unit inside the computer can start its work
  • Before it gets a signal from the console. In particular, the console regulates the execution of tasks in the processor so that it receives the tasks from the
  • Input and output and translate it if necessary and then pass it on to the next unit (unit of calculation and logic).
  • The console implements advanced methods to speed up the execution of programs, and it also controls the processor frequency, and you cannot upgrade
  • Or modifying this unit but rather an integral part of the CPU.
  • Third: Unit Logic / Arithmetic:
  • It is divided into three main sections, namely:

1- Floating-point unit:

  • It is very difficult for a processor to calculate floating point numbers – numbers with a decimal point – and examples thereof.
  • (2,336 / 2,5565 / 8,856,36532 / 0.222003) Because in this case, he will consume a lot of his power in practical accounts.
  • One, so a floating-point unit is added inside the processor and this unit is specialized in floating-point math operations,
  • It also plays a major role in the speed of running programs that rely heavily on decimal numbers and are often in
  • 3D games and engineering drawing software. The power of the large floating-point unit helped to accelerate dimensional games
  • The three, although the processor’s role has been reduced in this area thanks to the introduction of speedy graphics cards with their great strength.
  • There is a floating-point unit in processors (486) and later inside the processor – except for the SX486 processor – and it was
  • Placed in processors (386) and before, outside of the device, it is called “math processor-co”, that is, with the help unit.
  • The floating-point outside of the processor (on the motherboard) makes it slow compared to today’s processors, as all modern processors
  • It has a floating-point unit and not only this but an advanced floating-point unit.

2- Integer Numbers Unit:

This unit specializes in performing integer calculations and integers are used in two-dimensional applications.
Used in word processing. The strength of the integer unit is very important because most users use traditional applications.
usually.

3- Registrars:-

They are used to store numbers that the processor wants to perform their calculations on, as the processor can not perform any calculation until after
It brings the numbers to perform operations to the recorders. The records are physically located within the Calculation and Logic Unit.
The size of the recorders is important because it determines the size of the data that the computer can perform the calculations on, and the size of the data.
Registered by bit instead of byte because of their small size.

Fourth / Memory Cache:

The cache varies into three levels in modern processors (Cache L3 / Cache L2 / Cache L1) so that
Each has a specific function.

  • Level 1 cache (Cache L1):
    She frequently reads and writes data and instructions to and from random memory, and is the fastest of all others.
    Because of its small size, the size of this memory reaches (64 kilobytes).
  • Level 2 cache (Cache L2):
    It speeds up the flow of instructions to the processor and is considered to be faster than Cache L1.
    (1MB).
  • Level 3 cache (Cache L3):
    It speeds up the flow of instructions to the processor, but at a speed less than the speed (Cache L2), and it also bridges the gap between
    (Cache L2) and random memory, as it is considered an intermediate stage between them. The size of this memory reaches (8 megabytes).
