System on Chip(SoC):
A system on a chip or system on chip (SoC or SOC) is an integrated circuit (IC) that integrates all components of a computer or other electronic system into a single chip.
3
A typical SoC consists of:
•A microcontroller, microprocessor or DSP core(s).
•Memory blocks•Peripherals•External interfaces including industry
standards such as USB, FireWire, Ethernet
•Voltage regulators and power management circuits.
4
Example of a SoC’s structure
5
The so called “SMART” race
6
Mobile devices:
•Smartphones•Tablets•Portable media players•Personal digital assistants(PDA’s)•Blu-ray players•DVD players•Hand-held Gaming consoles
7
•Users today expect their mobile device to not only deliver long battery life but also provide the same full high definition web experience that they get from a PC.
•In addition to web browsing capabilities, users expect their mobile devices to handle a variety of use cases such as gaming, audio playback, navigation and photo/video capture.

Common mobile device architecture:
9
Power-Performance Paradox:
•Most mobile device architectures are designed around a general purpose CPU.
•The CPU not only underperforms but also consumes excessive power for today’s mobile use cases.
•Relying on a power hungry CPU either compromises battery life to offer good performance or delivers substandard experiences.
10
The mobile challenge:
The two main challenges are:
•High performance•Low power consumption
11
The Solution:
•NVidia's TEGRA Multi-Processor Architecture
•Use of a heterogeneous multi-processor architecture .
•A heterogeneous multi-processor by definition consists of several processors that are different in structure and function with each processor optimized for a specific purpose
12
8 Purpose optimized processors:•Dual-Core ARM Cortex A9 CPU(2)•ARM7 Processor•Ultra Low-Power Graphics Processor
(GPU)•HD Video Decode Processor•HD Video Encode Processor•Audio Processor•Image Signal Processor (ISP)
13
NVIDIA Tegra purpose-optimized processors
14
The Tegra line-up:
•Tegra APX series•Tegra 6xx series•Tegra 2 series•Tegra 3 series•Tegra 4 series
15
