  1. Introduction to Embedded Systems - Lesson 1: Definition, classification, Skills Required, Application Examples, .. Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  2. Definitions: “An Embedded System is a computer based system for an application(s) or product with dedicated software embedded in it. It may be an independent system or part of large system. – Present Book Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  3. “It is any device that includes a programmable computer but is not itself intended to be a general purpose computer.” – Wayne Wolf, Ref: 79 Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  4. “Embedded Systems are the electronic systems that contain a microprocessor or a microcontroller, but we do not think of them as computers- the computer is hidden or embedded in the system.” – Todd D. Morton, Ref: 77 Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  5. Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  6. Three Classes of the Embedded Systems Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  7. Small scale system – Single 8 or 16 bit microcontroller, little hardware and software complexities, C or Java as development platform, … Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  8. Medium Scale System - Single or few 16 or 32 bit microcontrollers or DSPs or RISCs, may also employ the readily available ASSPs and IPs in the hardware, use complex software design tools: ‘C’, Source code engineering tool, RTOS, IDE (Integrated Development Environment) as the development platform, … Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  9. Sophisticated system – enormous hardware and software complexities, may also employ scalable or configurable processors and FPGAs, needs hardware and software co-design and integration in the final system, used for the cutting edge applications, for example, an iPod or Smart mobile phone Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  10. Design Skills Requirement • Embedded System development is a team work of software and hardware engineers of various skills. Exemplary skills required are C/C++/Java/J2ME/Visual C++/.NET programming, RTOS programming, APIs, programming for device drivers, IOs, APIs and network interfaces, …. Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  11. Program and Design Modeling, Uses of Inter-Process Communication, Use of ICE, Lab Programming, Assemblers, Simulators, IDE, Debugging and Source code Engineering tools, Project Management, System Integration, .. Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  12. Exemplary Application Areas – Also refer to Section 1.5.1 pp. 37-39 Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  13. Summary We learnt • (i) definition of an embedded system, • (ii) classification of the embedded systems, • (iii) design team skills required and • (iv) exemplary application-areas. Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  14. End of Lesson 1 Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.

  15. Look at this sunflower, a nature’s gift – How does the nature embed its software? The flower rotates its face continuously towards the Sun. Chapter-1 L1: "Embedded Systems - Architecture, Programming and Design" , Raj Kamal, Publs.: McGraw-Hill, Inc.
