Mobile System Organization
harger and a battery unit, and provides power to the mobile system in required form.
Modern mobile system are tiny computer in your hand. They have less computing power compare to bigger versions of computer. We can perform various kind of tasks with the help of mobile like making calls , capturing images , playing games , listen to music , etc.
Mobile Processor:
CPU of a mobile system has majority two sub-processors:
- Communication Processing Unis: It is responsible for making and receiving phone calls. It has a digital signal processor that helps in work with RF Transceiver ( Radio Frequency ) and the Audio system. [ Radio Signal Management Unit- It connects SIM to the base station through radio signals]
- Application Processing Unit: It is responsible for governing, controlling all types of operation taking place on a mobile system.
2. Display Subsystem
This subsystem is responsible for providing display facilities, touch sensitive interface and touch sensitive keyboards.
3. Camera Subsystem
This sub unit is designed to deliver a tightly bound image processing package and enable an improved overall picture and video experience. It has an integrated Image Signal Processor ensures things like instant capture, high-resolution support, image stabilization, and other image enhancements.
4. Mobile System Memory
Like its other counterparts, a mobile system also needs memory to work. A mobile system’s memory is comprised of following two types of memories :
(i) RAM (Random Access Memory). It is a the work memory of your mobile system. The installed mobile apps, when run, are first loaded in the RAM and then executed. These apps remain in the RAM after you are no longer using them and then they are shifted to background.
(ii) ROM(Read Only Memory). The ROM (Read Only Memory) is a part of mobile system’s internal storage and it is not accessible for users to write on and is thus referred to as Read Only Memory. The ROM is basically Flash memory or technically EEPROM(electrically erasable and programmable read only memory).
5. Storage
The external storage of a mobile system is also called expandable storage. It comes in the form of SD cards, or micro SD cards etc. It is the storage which can be removed easily by you and can be used for storing pictures, music, videos and the likes. To an extent, even the cloud storage can also be categorized as external storage.
6. Power Management Subsystem (battery)
This subsystem is responsible for providing power to a mobile system. The mobile system work on limited power provided through an attached battery unit. This subsystem has a battery management system that works with a battery c
