What is a Processor in Computer and how does it work

What is a Processor in Computer: Do you know what is a processor in computer? Whenever we talk about a computer, of course, the processor comes to our mind. The computer is not possible without a processor. Yes, the processor’s efficiency is indeed less if it is less. However, all computers must have a processor. This processor has many names such as CPU, central processor, and microprocessor CPU its entire form Central Processing Unit. It is like the brain of a computer that monitors all activities. He handles all the instructions he gets from hardware and software. If seen, it is a hardware that does all the calculations very quickly, when it receives some input, processes it and after some computation, the result comes out. What is Computer Definition?

But do you know how this little thing processes so much information together? So today in this article we want to give you some information about what is a processor in computer and how it works. So what’s the delay? Let’s get started. Who invented the computer first?

It is highly important for the computer. The processor is also called the head of a computer. This is because it has information about all the activity that happens inside the computer, so it controls only these things. It can process trillions of calculations at a time. By understanding the explanations between software and hardware, it processes and gives us the output. It’s inside all devices like mobiles, tablets, personal computers, laptops. It is also known as CPU.

It is a square-shaped device in appearance, from which many metallic, short and circular connectors are dropped. It is connected to the CPU socket. After the long run, it gets a bit heated, which is why it has a heat sink and fan installed to release heat. This is a very fine thing, which is why it has been carefully placed on the motherboard. They come in many variants like Intel’s processors i3, i5, i7, and i9.

History of Processor

Intel first designed the world’s first single-chip microprocessor in the 1971s. It was invented by three Intel engineers, Federico Faggin, Ted Hoff and Stan Majo. This chip, called Intel 4004 microprocessor, was designed so that all processing functions, such as CPU, memory, and input and output controls were kept on a single chip. Gradually, innovation took place over time, resulting in many changes in computer design. Their working capacity has increased and their size has decreased. Intel is now the world leader in the processor. They make different processors according to the needs of the people.

Latest Processors in 2020 – Core i9

Intel has released its new Core i9, which Intel calls “the best gaming processor in the world.

In addition to the new Core i9 processor, Intel is also announcing new 9th General Core i5 and Core i7 models: i7-9700K with eight cores and eight threads and a base 3.6 GHz clock speed (which can be upgraded to 4.9 GHz); And the i5-9600K, which provides six cores and six threads at base 3.7 GHz speed (which can be increased to 4.6 GHz).

And for professional users who need even more firepower, the Intel Zion has announced a new W3175X processor with 28 new cores and 56 threads unlocked. The base clock speed will be increased to 1.5 GHz, 1.5 GHz and it will be shipped later this year in December. No prices have been announced yet, but it won’t be cheap if it hits stores.

What does CPU Work

The CPU has three basic functions, first, it takes information, second, it performs some operations on it, and third, it returns the result after computation. But to process all three, it has to use some key elements. ALU (arithmetic and logic units) subtract and add to binary. Also, they perform some logical operations such as AND, NOT and OR to assist the CPU. The control circuit directs data traffic from the CPU to slow input/output devices so that traffic can be exchanged. The memory management unit monitors data flow to and from memory.

Types of CPU (what is a processor in computer)

Over the past few years, many types of CPUs have evolved. Over time new CPUs were made as needed. The number was used earlier to identify the processor. For example, Intel 80486 (486) processors are much faster than 80386 processors. Since Intel released Pentium processors (technically they were 80586), the processors were named Athlon, Duran, Pentium, and Celeron.

Nowadays, the use of processors with similar architecture with their architecture names has changed, now 32 bits and 64 bits are used. Due to this architecture, the speed and capacity of the processor have now increased significantly. Processors such as the AMD Opteron Series and Intel Itanium, Zion Series are used on servers and high-end stations. And if we talk about small devices like smartphones and tablets, they use ARM processors. These processors are smaller in size than normal, require less power and produce less heat.

What is the processor clock speed?

Clockwise is the microprocessor called the motion that executes every direction of the clock or every vibration. This is because the CPU needs a certain number of clock ticks or cycles to execute each command. So your clock rate is faster, your CPU will be faster or your processor can execute instructions faster.

Clock speed is measured at MHz, 1 MHz means 1 million cycles per second or GHz, 1 GHz means 1 million cycles per second. In general terms, the higher the CPU speed then the better your computer will be. Computer speed also depends on other components such as RAM, hard drive, motherboard, and several processor cores (such as dual-core or quad-core).

This CPU speed shows how much it can count in 1 second. The higher the speed, the more computation you can perform which will make your computer run faster. Computer processors of different brands are available in the market such as Intel and AMD, but they all follow the same CPU speed standard to know what speed the processor is running.

What is Core in Processor?

Processors have different cores depending on their capabilities. A typical processor has a single-core, meaning it is a single CPU. Dual-core processors have two processor circuits with two identical frequencies. It can easily operate at twice the speed of a single-core processor.

There are many different core processors in the market today.

NameNumber of Core
Dual-Core2 Core
Quad-Core4 Core
Hexo-Core6 Core
Octa-Core8 Core
Deca-Core10 Core

The more cores the processor has, the more successfully it can complete multitasking.

How Processor Works

The design of the processor is much more complex than the general design and they are different from one company and even one model is very different from the other. At the moment, there is a great demand in the processor market of two companies like Intel and AMD. These two companies are always engaged in trying to figure out how to improve processor efficiency by using less space and power. But despite the many architectural differences, the processor basically has to go through four processes and only then can they process instructions. These four processes are a feature, decode, execute and write-back. Here, We will tell about these processes step by step.

1. Fetch

Fetch as if it means bringing something.. Here the processor retrieves the original instructions waiting for memory. However, in today’s modern processors, these instructions are already waiting for the processor cache. The processor has a region called a program counter that acts as a bookmark, letting the processor know where the last instruction ended and where the next one began.

2. Decode

After Fetch, the next process is to decode. There are many areas of the processor core in any direction that mathematical and processor cores need to recognize. Each part called Opcode contains something that tells the processor what to do using that command. Once the processor recognizes what he has to do, he then does everything himself.

3. Execute

In this step, the processor knows what he has to do and he executes it. What happens here depends on what field the processor core uses and what information is added to it. For example, the processor uses ALU to perform a mathematical operation. It is believed that this operation occurs within ALU. This unit is connected to other inputs and outputs so that it can simplify its work and ultimately we can give our results at the right time.

4. Writeback

This last step can also be called, as its name implies, that it remembers the results of the three previous works. Output depends on which application is being run at that time. But it is usually in the processor’s account because it is needed very much, but it is kept here for quick access.

This whole process is called the instruction cycle. As we progress, we have better processors that are much faster and stronger. Our CPU is designed so that it shares many tasks so that it can process as quickly as possible. And with new discoveries, it seems possible.

Conclusion about what is a Processor in Computer

Soon, we will see more advanced processors. Because nowadays all the processor companies are focusing more on how the processors can be designed in less time and in less energy. And it should be more efficient. If we compare the processors of the past with the design of today, we have been very successful in this mission and hopefully, in the future we will be able to build more efficient processors.
