Types of processors How it Works?

Today we are leaving in the era of smartphones and tablets. And in the past decade technology has been evolved so much that using this smartphone and tablets we can do almost all the stuff that we are used to doing with desktop and laptop. So using this smartphone and tablet do stuff like gaming, web browsing, photo editing, creating documents, media streaming, and many more things. And yet these devices are quite compact compared to the desktop and laptop. And yet they contain almost all the parts which you see inside the desktop and laptop.

    1. Motherboard

So, almost all the components that you see inside the motherboard of any laptop or desktop are integrated inside a single chip in the smartphone. So, the entire system which is required to run a smartphone is integrated into a single chip. And that is known as an SoC or System on Chip. And thanks to the leading manufacturers like Qualcomm, Samsung, Apple, Kirin, and MediaTek it is possible to integrate all the components inside a single chip. And sometimes if you see the size of this system on Chip, they are as small as the size of a coin. So, now the question is how is it possible to integrate all the parts inside a single chip.

2. Smartphone vs PC (Processor)

So, there are many reasons behind that. So, let's find out these reasons. The first reason is the processor that you see inside the smartphone is not a powerful as the processor which you find inside the desktop and the laptop. 

So, don't get me wrong. The processors which you see inside the smartphones are powerful enough, but if you compare them with the processors of desktop and laptop, the processors in desktop and laptop are quite powerful.

 So, if you have seen any motherboard of any laptop or desktop, you must have observed that the processor is enclosed by the heatsink and the cooling fan. Because these powerful processors generate a lot of amount of heat. 

And they need some sort of cooling. So, just imagine the size of your smartphone if the same processor with all the cooling arrangements is fitted into your smartphone. 

Forget about the cooling, if you put this processor inside your smartphone then your battery of the smartphone would die in just half an hour. Because these processors are quite power hungryand require a lot of amount of power. So, the fact is that processors that you see inside a smartphone and tablet are designed using a different architecture.

3. arm architecture

    

So, most of the processors which you see inside the smartphone and tablet are designed using ARM architecture. The System on Chip which is designed using this ARM architecture is quite powerful as well as power efficient. One more thing is that the operating system which is designed for these smartphones is optimized for this system on chips. 

So, although on paper these smartphone professors don't look powerful compared to the desktop processors, because of this software optimization, you hardly feel any lag when you operating these smartphones and tablets. 

Apart from that, the advancement in manufacturing technology has allowed us to integrate more and more transistors inside the same area. So, not only on the smartphone but on desktop and laptop also, you will see that many parts are integrated inside the same chip. So, these are some of the reasons why you can integrate all the components inside a single chip. 

4. Processor

So, the first thing that you find inside the system-on-chip is a processor and we have talked so much about this processor.

5. GPU

So, the next thing that you will see inside the SoC is GPU. Which is known as the Graphical Processing Unit? And it is responsible for all graphics-related activity inside your smartphone or tablet.

6. DSP

The next thing which you see inside the System on the Chip is DSP. Which is known as Digital Signal Processor? And it is responsible for the activities related to audio processing, video processing, and somewhat related to display.  

So, in some systems-on-chip, you will find this audio and video processing module as a different module. While in some cases, they are integrated inside the same module.

7. RAM

The next thing that you will see inside this system on Chip is the memory element. Which contains the storage memory, that isRead only Memory. And the volatile memory, that is Random access memory.

 

8. Connectivity

So, now the next module that you see inside the system on the chip is the connectivity module. And this module ensures that the user has all kinds of connectivity. Like Wi-Fi, FM radio, USB, Bluetooth, sometimes GPS, and Cellular Radios. So, these are the basic module that you will see inside the System on Chip.

 

9. Other parts

Apart from this, some higher-end System onChip also contains some other modules, like module for the camera, location, Security, and the sensors. Now, sometimes due to the size constraint, it is not possible to integrate. 

The Random Access Apart from this, some higher-end System onChip also contains some other modules, like modules for the camera, location, Security, and the sensors. Now, sometimes due to the size constraint, it is not possible to integrate the Random Access Memory or RAM inside this System. 

So in such scenarios, the memory package is stacked above this System on Chip package. And they ate connected using this ball grid array. So, this kind of packaging arrangement is known as a Package on Package arrangement. And this type of Package on Package arrangement reduces the cost as well as the size.

10. Modules today's System on Chip

Now in the scenarios, where memory is outside the System on Chip, you need to establish the connection between the CPU and the memory. And that is done by the module known as Northbridge. So, this module ensures the connectivity between the RAM and the CPU. So, these are the modules you will find inside today's System on Chip.

So, guys, I meet you with my next blog and you have any suggestions for me tell me in the comment section.

Thank you very much for giving me your important time 

GOODBYE.
