System on Chip(SoC):

A system on chip (SoC orSOC) is an integrated circuit(IC) that integrates all

components of a computeror other electronic systeminto a single chip.

A typical SoC consists of:

A microcontroller, microprocessor or DSP core(s).

Memory blocks

Peripherals

External interfaces including industry standards such as USB, FireWEthernet

Voltage regulators and power management circuits.

Tegra is a system on a chip (SoC) series developed by NVidia for mobile dsuch as smartphones, personal digital assistants, and mobile Internet deviceTegra integrates an ARM architecture central processing unit (CPU), graphprocessing unit (GPU) and memory controller onto one package. The serieemphasizes low power consumption and high performance for playing aud

video. The Tegra 4i (codenamed "Grey") was released on 19 February 2013

The NVIDIA Tegra 4i has one of the highest performing CPUs with a maclock speed of 2,300 MHz. It has 5 core(s), resulting in extremely efficient tasking when compared to dual core processors.

Most mobile device architectures are designed around a general purCPU.

The CPU not only underperforms but also consumes excessive powe

todays mobile use cases.

Relying on a power hungry CPU either compromises battery life to ogood performance or delivers substandard experiences.

NVidia's TEGRA Multi-Processor Architecture

Use of a heterogeneousmulti-processor architecture .

A heterogeneous multi-processor by definition consists of several pr

that are different in structure and function with each processor optim

a specific purpose

Use Case Battery Life Estimates

Stand by (Display & Radio off) 2000 Hours

128 Kbps Music Playback 140 Hours

HD Video Playback on local LCD 8 Hours

HD Video Playback on external LCD(via HDMI) 16 Hours

Performance and Battery Life:The following use cases illustrate battery life a user can expect from an NVID

Tegra-based tablet (with 2000 mAh battery and 400 mW display)


13/16

Lower power consumption , Higher performance per watt

Faster Web page load times

Higher Performance for demanding applications

Faster Multitasking

Higher Quality Gaming

Advantages:

Conclusion: Smartphones and tablets are increasingly being used as personal computin

devices.

Todays smartphonesare no longer being used for just phone calls, messagi

light Web browsing.Mobile applications for PC-class use cases such as pho

editing, word processing,multi-tabbed Web browsing,modern graphics-rich

gaming,and multi-tasking arenow availablefor mobile devices and are push

performance requirements of these devices.The quad core CPUs in NVIDTegra 4 family of mobile SoCsinclude several key enhancements thatdelive

performance for thenext generation of mobile applications.
