This presentation discusses the different CPU architectures used in Android devices, including ARM, Intel, and MIPS. ARM is the most popular and uses energy-efficient RISC designs. Popular ARM vendors are Qualcomm, Texas Instruments, Nvidia, and Samsung, who integrate ARM cores into system-on-chip (SoC) designs. Intel produces x86 processors for Android via the Atom platform. MIPS is another RISC architecture used in some devices. The presentation explores the processor designs and vendors that power popular Android smartphones and tablets.

MOBILE PROCESSORS IN NOWADAYS AVAILABLE MOBILE AND TABLETS.Today’s smartphone and mobile processors are very powerful, so powerful that it is almost as powerful as a desktop computer. Processors are now coming up with more cores. Initially it was Single core, and then came Dual core; we now have Quad core, Hexa core and even Octa core. Most processors are 64 bit now as against 32 bit when it started initially. The processing speed has reached up to 3.0 -3.5 GHz. The ability to include GPU (Graphic Processing Unit) inside mobile processors has enabled devices to churn out the best graphics picture, 3D capability, Virtual Reality capability and 4k recording. The improved processor technology also made today’s modern mobile devices more power efficient. In this article we will learn different processor used in mobile, tablet, and laptops.

This issue of AXIOM is dedicated to processing and power and in these pages we bring together a team of industry experts to talk about what you need to know in these areas. Avnet’s advanced architechtures expert Jim Carver gets to the heart of the ARM processor cores – explaining the history of ARM’s first offering through the current ecosystem of products, as well as and their functionality. And because no one likes to be in the dark, Chris Ammann explains why it is so critical for FPGA designers to plan for their board power at the beginning of the design process. Doug Geisler looks at how industrial OEMs have started to act like consumer electronics companies, or the “consumerization” of the market, and outlines the benefits and challenges to this new experience.

Arm processor architecture awareness session pi technologiesPiTechnologies
ARM processor is widely used in Embedded devices such as smart phones. Market share of ARM in embedded industry exceeds 90%.
This awareness presentation about ARM architecture presented by PiTechnologies Group www.PiTechnologies.net
Processors are essential for the functioning of computer systems, providing the necessary computational power, control, and coordination to execute instructions and run software applications efficiently. They are the "brain" of the computer, handling tasks ranging from basic calculations to complex operations, enabling multitasking etc.
Snapdragon is a family of mobile systems on a chip (SoC) by Qualcomm. Qualcomm considers Snapdragon a "platform" for use in smartphones, tablets, and smartbook devices.
ARM is a family of RISC-based microprocessors and microcontrollers designed by ARM Inc., Cambridge, England.
ARM chips are high-speed processors that are known for their small die size and low power requirements.

2. CPU Architectures for Android Devices
The CPU executes a sequence of instructions to control
the hardware on your device.
Android supports 3 different processor architectures:
• ARM
• Intel
• MIPS
These three CPU designs are for both 32-bit and 64-bit
solutions.
3. INTRODUCTION
The most popular and ubiquitous of these three is the ARM.
(Advanced RISC Machines).
Intel is well known for of its popularity in
the desktop and server markets, however on
mobile it has had less of an impact.
MIPS is a reduced instruction set computer
(RISC) instruction set architecture (ISA)
developed by MIPS
TECHNOLOGIES .
4. Inside the SoC
The device consists primarily of :
Chipset - typically split into -
• A Northbridge that connects to the processor and memory
• A Southbridge that connects to various peripheral buses.
A Central Processing Unit (CPU)
Application Memory (RAM)
Permanent Storage (Micro SD)
A Graphics Processing Unit (GPU)
A Power Supply
Peripherals
5. Efficiency vs Performance
Mobile devices are complex devices.
CPUs need to execute millions of instructions to make them
behave as we expect.
The speed and power efficiency of these CPUs is critical.
The speed affects the user experience, while the efficiency
affects the battery life.
The perfect mobile device is one that has high performance and
low power usage.
Efficiency Performance
6. ARM
