SoC

  • System on a Chip
  • Smaller
  • Less Heat
  • Less Energy
  • a system on a chip
  • designed to support applications 
  • self contained operating environment

provides

  • all system capabilities required to support mobile applications
  • Mobile processors may be independent from other specialized processors in the same device, such as a phone's baseband processor

including 

  • memory management
  • graphics processing and multimedia.

A mobile processor is

 

Vendor

  • Some vendors manufacture their own mobile application processors.
  • Other vendors purchase their mobile application processors, using them as original equipment manufacturer components.

For Example,

The Qualcomm Snapdragon mobile phone application processor is contained in many smart phones that use Qualcomm Snapdragon to run the Android mobile phone operating system and Android mobile applications.
  • CPU
  • GPU
  • Bluetooth
  • Wifi
  • GPS
  • Cellular

Mobile Phone Processor Architecture

Architecture of Processors

 

SoC processor cores often use the ARM architecture because it is a soft processor specified as an IP core and more power efficient than x86.

Intel However has tried manufacturing x86 processors but hasn't succeeded.

Intel is better with Computer Processors

ARM has licenses companies to use it's architecture. Such as Apple and Qualcom

CPU Clock and Cores

which one is faster 2.0 GHz or 2.5 GHz?

  • Simple task
  • Multiple cores
  • Multi Tasking
  • Each Core 1.5 GHz
  • Faster
  • Less Heat
  • Less Eneregy
     
  • Architecture Matters!

which one is faster Octa Core Exynos, Qual Core SnapDragon, Dual Core A8?

  • Softwares
  • Device Optimization
  • Apple Manufactures it's own Processors but Samsung Doesn't!!

32-bit or 64-bit

  • Apple's first 64-bit Device : Iphone 5s
2013
  • Samsung's first 64-bit Device: Galaxy S4
Late 2014

which one is faster?

  • Able to do more tasks
  • Able to use more than 4Gb RAM (not necessary)
  • Doesn't Necessary Make it Faster
  • ARM v8 : first 64 bit Architecture

lithography

  • Less Energy
  • Less Batter
  • Faster
  • More Powerful
  • The Shorter The Better
  • Made Smaller and with Less Heat
  • Samsung Galaxy S6 : 14 nm
  • Samsung Galaxy s7: 10 nm
  • Apple Iphone X : 7nm

GPU

  • Graphical User Interface
  • Games
  • Animations
  • Best Core Processor looks weak if GPU is weak!!
