Introduction: At present, all the computing devices, from toys to any big business system, a common thing is the central processing unit. A CPU processor is a computer chip that is the equivalent of a matchbox. Inside the package is a silicon rectangle with millions of transistorized circuits. There are dozens of metals pins lying in the device, In which each chip emits an electronic signal from the inside out. The chip is connected to the socket plug of the computer’s circuits board. That is the memory for the CPU. The hard drive, Display screen communicates with other devices.
WHAT IS THE CPU PROCESSOR? The CPU calculates and makes logical comparisons and carries the data back and forth every second to the processor which is also called CPU. There is a logic circuitry that responds and processes the basic instructions of those who run the computer. The CPU is seen as the computer’s main and most important integrated circuitry (IC) chip, as it is responsible for running most of the computer’s commands. Run commands for another chip. The processor is often called the CPU. But CPU is not the only processor of a computer. GPU or Graphics Processing Unit is the biggest example of this. Also, the hard drive inside the computer and all the other devices do the processing work separately. However, in general, processor means CPU. Processors can be found on PC, smartphones, tablets,s, and other computers. At present, the processor has two main competitors which are Inter and AMD.
WHAT IS THE BASIC ELEMENT OF THE PROCESSOR? If we do not know the basic elements of the processor, we will not understand how a processor works. the elements of the processor are :
- Arithmetic Logic Unit (CPU): There is a circuit between ALU and processor. It contains Arithmetic and Logical. It calculates and compares, it completes the instructions of logic & arithmetic.
Logic & Arithmetic Example
A>B C= A+B
14>10 C = 14 + 10
A is big C = 24
For arithmetic, the CPU most of the time does basic multiplication, addition, division, and subtraction. and complex math can be solved easily and quickly.
ALU also compares the two data, whether the two are equal or the first is larger than the second.
A = B * A > B ✓
- Floating Point Unit (FPU): which is known as math as processor and numeric as processor. It is a special co-processor, which can solve the problem by manipulating numbers much faster than the contract basic micro processor circuitry.
- Register: It stores any instructions or any other data. Register supplies operaions to ALU and stres the results of operations.
- L1 and L2: ( CacheMemory ): Used to collect data faster than RAM.
WHAT IS CPU OPERATION?
The first four functions of the processor in CPU operation are 1) Fetch, 2) Decode, 3) Execute, 4) Writeback
- Fetch: This is an operation that takes instructions for RAM from program memory.
- Decode: Decode is a place where instructions are decoded.
- Execute: Execute a place where the operation is performed.
Each part of the CPU is required to complete instruction in this way.
COMPONENTS OF CPU: The main components of CPU are ALU, Register, Control Units.
The basic functions of ALU and Register have already been mentioned. Now let’s talk about control units.
The control units are bringing the indicators and match all of them. It balances the movement with the rest of the processor. The controls unit breaks down the action of each instruction at once and instructs the rest of the CPU to perform the action.
The processor is housed in a personal computer or a small corner. This is often called a microprocessor. This means that the processor’s elements are contained in an IC chip, which some computers use using a multi-core processor, which means a chip with more than one CPU. A CPU is usually attached to the motherboard.
THE WORKING PROCESS OF CPU: Before exiting any instructions, first the program instructions data must be stored in the memory of an input device or a secondary storage device. Here the emergency data will reach the instructions memory then the CPU follows four steps for each instruction. E.g.
- CPU collects instructions from memory.
- The CPU decodes instructions and instructs to move emergency data from memory to LU.
The 1st and 2nd steps together are called instuctions Time or E- Time.
- then solve the arithmectic / logic unit.
- AIU stores the result in memory or Register.
The 3rd and 4th steps together are called Execution Time or E-Time.
HOW DOES THE PROCESSOR WORK IN THE SYSTEM? : Most processors are multi-core, which means that the IC has two or more processors. With the help of which the performance can be made better. Multi-core set-up is like installing different processors on the same computer. Most computers have 2-4 cores. But it can be up to 12 cores. For example, if a CPU can process a command at once, it is called a single-core processor. Or if a CPU can process 2 sets of indicators at once.it is called a dual-core processor. The more cores there are, the more instructions a computer can give. Virtualized processor core is used using some multi 3D. Virtualized processor core is also called v CPU and it is not as strong as a physical core. But virtual machine VM is used to make the display better. Unnecessary v CPU pairing can result in loss of consolation rescues. For this, there needs to be at least 4-6 v CPU with each physical core.
