Chaired a Technical Session in NATIONAL CONFERENCE ON EMBEDDED SYSTEMS & SIGNAL PROCESSING (NESP-2014) (Jain University) My Lead talk title of the presentation: Trends and Implications in Embedded Systems Development

1. NATIONAL CONFERENCE ON
EMBEDDED SYSTEMS & SIGNAL
PROCESSING
(NESP-2014)
Trends and Implications in
Embedded Systems
Development
Prof Shivananda R Koteshwar
23rd January 2014

2. Application Areas
Prof Shivananda R Koteshwar

3. Lets look at the building blocks
Prof Shivananda R Koteshwar

4. Needs
Low cost
 Small physical footprint
 Negligible electrical / electronic radiation and
energy consumption
 Need to be physically rugged and impervious to
external electrical and electronic interference

System-on-chip (SoC) architecture
 Application of short range protocols
 Real time responsiveness

Prof Shivananda R Koteshwar

5. Trends and Implications
Multi-Core Processors



Multi-threaded architecture  Multi-core programming
Requires a paradigm shift for embedded applications - engineers
need to update their architecture, design, programming, debugging
and testing
Entire ecosystem need to respond to the standardization of
technology — in terms of debuggers, RTOS, compilers, integrated
development environment (IDE) vendors and programming
methodologies.
Heterogeneous
Multi Processing
Prof Shivananda R Koteshwar

6. Trends and Implications
Wireless

Trends
 Short-range
wireless protocols like Bluetooth, Zigbee, RFID,
near field communications (NFC)
 Long-range protocols such as, wireless local area network
(WLAN), WiMAX, long term evolution (LTE)
 Cellular communications

Implication
 Soc
Architecture
 Power Consumption
 Short range Protocols
Prof Shivananda R Koteshwar

7. Trends and Implications
Increased use of open source technology

Trends


Support from giants – Microsoft and Google


Proprietary hardware, software, communication protocols  Embedded Linux,
RTOS with royalty free licenses
Eclipse, the open source project for building development platforms offers an
environment that crosses over RTOS boundaries. It comprises extensible
frameworks, tools and runtimes for building, deploying and managing software
throughout its lifecycle
Implication

Open source tools by itself should not be the sole criterion for its selection.
Engineers may be tempted to use open source tools even when it may not be
the best possible solution.

Further, for any open source tool, there is always certain tuning required which
are resource-constrained and have real-time requirements.
Prof Shivananda R Koteshwar

8. Trends and Implications
Security

Trends
 Embedded
security is the new differentiator for
embedded devices
 Must consider the implications of intercepted, deleted,
modified and forged information and develop
prevention techniques

Implication
 Embedded
Encryption
 Elliptic Curve Cryptography
 Trusted Computing
 Authentication Techniques
Prof Shivananda R Koteshwar

9. Trends and Implications
Device Convergence

Trends
+ Entertainment  Infotainment
 Seamless connections of divergent product
 Information

Implication
 Digital
Living Network Alliance (DLNA) guidelines
 Media oriented systems transport (MOST) in
automotive industry
 Convergence of multiple functions into a single device
and the plug and play functionality for use with other
devices will continue to drive the development of
embedded systems
Prof Shivananda R Koteshwar

10. Trends and Implications
Internationalization

Trends
 Manufacturers
have access to global markets, so
localization and personalization of devices falls within
the ambit of baseline features

Implication
 Providing
multi-language support on embedded
devices is accompanied by many challenges; the
major ones are the limited memory to store the font
related information (bitmap font, outline font, glyph,
character, tone etc.), CPU processing power, size of
the script engine and the small resolution of the
display screen. The low resolution usually degrades
the readability of the display text.
Prof Shivananda R Koteshwar

11. Trends and Implications
Smart Devices

Trends


Machine to machine (M2M) communication, through both wired
and wireless mechanisms is on the rise
Implication
Devices can offer valuable inputs to OEMs and service providers
helping in innovating advanced features or upgrades
 It will also open up new after-market revenue streams – so
specific features can be targeted to users depending on their
device usage patterns and preferences
 Embedded devices already have intelligence built into them. It is
only the manner in which this intelligence can be better
harnessed or enhanced that is being subjected to a major
change. Therefore, from being mere “intelligent” devices, they
are poised to become “smart” devices.
