1. Applications of Embedded Systems Difference between General Purpose System and Embedded System Characteristics and types of Embedded Systems What is Embedded System Career Opportunities

2. Embedded System Digital Camera WHAT IS EMBEDDED SYSTEM ? HARDWARE "It is a combination of hardware and software intended to perform a specific task “. An embedded system is a computer system (combination of hardware and software) with a dedicated function within a larger mechanical or electrical system. Embedded system = information processing systems embedded into a larger product HARDWARE Computing system Kodak film camera Task of capturing image Addition task

3. “Any sort of device which includes a programmable computer but itself is not intended to be a general-purpose computer” Marilyn Wolf

4. Components of Embedded Systems

5. Real Time Examples of Embedded Systems

6. APPLICATIONS OF EMBEDDED SYSTEMS EVERYWHERE

7. Is Desktop/Laptop computers an Embedded System ???? A desktop computer is considered as a General Purpose System as it can do many different tasks (playing videos, working on office suites, editing images (or videos), browsing the web, etc.) that too simultaneously . An Embedded System is an application oriented system i.e. it is dedicated to perform a single task (or a limited number of tasks, but all working for a single main aim).

8. Embedded system often includes task-specific hardware mechanical parts not usually found in a general-purpose computer.

9. DIFFERENCE BETWEEN GENERAL PURPOSE SYSTEM AND EMBEDDED SYSTEM General Purpose System Embedded System Designed to perform multiple Tasks Designed to do specific set of Tasks Task specific hardware component is not required Requires task specific hardware component High Power consumption Low Power consumption Programmable by end user therefore applications are alterable by the user Not Programmable by end user therefore applications cannot be altered by the user

10. Is Mobile Phone an Embedded System???? A first generation digital mobile phone , is probably certainly an embedded system.

11. Modify (Install/uninstall) the applications but, smartphone comes with pre-installed Operating System (OS) that cannot be modified. Functionality of smartphones cannot be upgraded . As these conditions are in line with embedded system definition. smartphone can be viewed as combination of various embedded systems i.e. Camera, Various sensors, Calling function etc. It is not general purpose computer in true sense. Smartphone is an Embedded System

12. CHARACTERISTICS OF EMBEDDED SYSTEM High Reliability Characteristics of Embedded system Minimal User Interface Complex Algorithm Multirate Real Time Task Specific Low Cost Less Power

13. TYPES OF EMBEDDED SYSTEMS Based on Performance and Functional Requirements Based on the Performance of the Microcontroller Real Time System Stand Alone System Networked System Mobile System Small Scale System Medium Scale System Sophisticated System

14. Stand Alone Embedded System Does not require a host system Takes input, processes it and produces the result through the connected devices.

15. Real time Embedded System Produces output within a specified time limit. Gives quick response to critical situation Types of Real time Systems Hard Real Time System Entire system collapses if misses deadline 2. Soft Real Time S ystem Missing deadline will only degrade the performance.

16. Networked Embedded System Connected to the network (LAN or WAN) to access the resource Mobile Embedded System Used in portable devices like mobile phones, digital cameras, mp3 players.

17. Based on the Performance of the Microcontroller Small Scale System Medium Scale System Sophisticated System

18. Is Embedded Systems a good career option ? or What are the career opportunities in Embedded Systems Industry ? Embedded Software Engineer Computation Sensing Embedded Programmer Digital system Manager Smart System Administrator Digital System Architect Embedded Software Architect Embedded Developer

19. Industry Outlook - G lobal Embedded System Market

20. Global Embedded Systems in Automobile market size by product

21. THE LEADING EMBEDDED SYSTEM COMPANIES

22. What Skills you should have ? 2. Hardware Skills Electronic Circuit Designing Power Supply Circuit Designing PCB Designing Troubleshooting Skills High-speed board design of Microcontroller or Processor and peripheral devices like SPI, I ²C, USB 1.  Software Skills Embedded Programming (Embedded C, C++, Assembly language, Python, Verilog, Rust, Ada) on Microcontrollers (AVR, PIC, ARM) Interfacing microcontrollers with different sensors and peripheral Kernel Programming Device Drivers Real Time Operating Systems (RTOS) Innovative Thinking

23. 3. Other Skills Learning new microcontroller interfacing yourself Learning new hardware yourself Reading Datasheets Documentation as per company norms Working in a Team Completing Work in Deadlines Making Reports as per the Company Requirement
