Transcript

  • 1.  To Introduce embedded system. To introduce embedded system designprocess. Discuss the recent trends. Major application areas.
  • 2.  It can be described as one consisting aprocessor, associated peripherals, andsoftware used for a specific purpose. It performs a well defined task (in contrastwith desktop PC’s)
  • 3. . Stand-alone embedded system.. Stand-alone embedded system. 2. Real-time embedded system.2. Real-time embedded system.3. Networked appliances.3. Networked appliances. 4. Mobile Devices.4. Mobile Devices.
  • 4. 1) Processor.1) Associated peripherals.1) Software.1 0 0 1 0 1 0 00 1 1 1 1 0 1 01 0 1 0 1 1 0 1
  • 5. • Microprocessor.• Microcontroller.• Digital signal processor.
  • 6. 1. Protocol converters.2. Communication interfaces.3. Drivers (For driving heavy loads).
  • 7. It is a program written inany programminglanguage, which controlsthe operation of the totalsystem.
  • 8. Determine the requirementsDesign the systemarchitectureSelect the OSChoose theProcessorand peripheralsChoose theDevelopmentplatformCode the applicationAnd optimizeVerify the softwareOn the host systemVerify the softwareOn the target system
  • 9.  Functional and non-functional. Multi function or Multi mode system. Size, cost, Weight etc. Selecting the H/W components. Application specific H/W. External interfaces. Input devices. Output devices.
  • 10. System architecture depends on, Whether the system is real time. Whether OS needs to be embedded. Size, Cost, Power consumption etc.
  • 11. If OS needed we can select, Real time OS (such as RTLinux,Vx Works,VRTX, pSOS, QNX etc.). Non-real time OS ( such as Windows CE,embedded Windows XP etc).
  • 12. We can select any one of the following, Microprocessor8085,8086,Pentium MicrocontrollerMCS-51,PIC,AVR,MSP430 Digital Signal ProcessordsPIC,Blackfin,Sharc,TigerSharc
  • 13.  The hardware platform. The operating system. The programming language. The development tools.
  • 14.  Choice of language. Assembly. C language. Object Oriented Languages(C++, Java etc.).• Optimizing the code
  • 15.  Compile and assemblethe source code intoobject file. Use a simulator tosimulate the working ofthe system.
  • 16.  Download the programusing a programmerdevice. Use an EMULATOR oron chip debugging toolsto verify the software.
  • 17.  Due to the developments in Micro electronics availabilityof processors increased. Reduces cost. Increased speed. Reduce Size Reduce Power.
