Mobile Phone Chip Faults.
Latest mobile smart phones are packed with features and facilities that require processing power in the form of integrated circuit technology. So how many architectural functions are there in a mobile phone, how many chips and do they go faulty?
Smart Phone Architecture.
The functional building blocks of a mobile phone are:-
microprocessor, read only memory (ROM), random access memory (RAM), radio, digital signal processor, microphone and speaker, hardware keys, interfaces and a liquid crystal display (LCD). The OS may be stored in either NAND or NOR memory while code execution typically occurs in RAM. The functionality is usually on a single chip termed a System on a Chip (SoC).
Processors have memory size options of circa 16, 32, 64 and 128GB and the phones also have Secure Digital (SD) memory card slots, non-cellular Bluetooth and WiFi are also built in to the device that support synchronization protocols to exchange data such as graphics, audio, and video file formats). Different mobile devices have different features and facilities such as GPS, Cameras etc.,
The performance of the processors has tended to grow exponentially new product release upon new product release. The ever popular iPhone product processor functionality has progressed as follows :- iPhone 4S, has dual core A5 processor of unspecified speed, the iPhone 5c and the iPhone 5s, a 64-bit “A7 chip +M7 motion coprocessor, iPhone 6 have an A8 chip with second generation 64-bit desktop-class architecture and the iPhone 6s have a third-generation 64-bit” A9 processor. It only seems like last year that we were raving about the iPhone 4 ! and now your provider is pushing an iPhone 6.
Most users really don’t need to know or even care about the size or speed of the processor in their smart phones , they really only care about the features and functionality they provide and how effectively the smart phone can deliver these. It is this that ultimately drives the chip performance and architecture.
So back on message “how many chips and components are there in a smart phone?” Well apart from the screen and power components you are looking at two or three multifunction chips
“Do these components go faulty?”
The answer is ; very infrequently and generally as a result of mistreatment. The rapid churn in the market place dictates that devices rarely break down due to component over utilisation, the market for smart phones being largely dictated by technology pull rather than consumer push.
