Presentation 3

  1. 1. EMBEDDEDSYSTEM
  2. 2. Introduction An embedded system is a computer system designedto do one or a few dedicated and/or specific functions “Embedded System", it constantly evolves withadvances in technology and dramatic decreases in thecost of implementing various hardware and softwarecomponents. In recent years, the field has outgrown many of itstraditional descriptions.
  3. 3. Basic PrinciplesAlmost all the Embedded Systemapplications share a common EmbeddedSystem model which includes:Hardware LayerSystem Software LayerApplication Software Layer
  4. 4. Embedded SystemDesigning andArchitectureIn order to design an EmbeddedSystem certain processes are asfollowed:CreationImplementationTestingMaintenance
  5. 5. General Characteristics ofEmbedded SystemsPerform a single taskUsually not general purposeIncreasingly high performance and real timeconstrainedPower, cost and reliability are importantconsiderationsHW-SW systemsSoftware is used for more features andflexibility(R.T.O.S)Hardware (processors, ASICs, memory etc. areused for performance and security
  6. 6. Types of EmbeddedSystem General ComputingVideo games, set-top boxes, wearable computers,Automatic tellers Control SystemsVehicle engines, chemical processes, nuclearpower, flight control Signal Processing Radar, Sonar, video compression Communication & NetworkingTelephone system, Internet
  7. 7. Economical AspectEconomical metrics are mostly used todetermine which COTS should be use or if thesystems will be brought into the market.Unit CostNon-Recurring Engineering (NRE)FlexibilityTime to Market
  8. 8. ApplicationsAutomotive ElectronicsAircraft ElectronicsTrainsTelecommunication
  9. 9. Application (contd)Consumer electronicsFabrication equipmentSmart buildings
  10. 10. Application (contd)Medical SystemsScientific ResearchMilitary ApplicationsIndustrial ApplicationsSecurity System
  11. 11. Brands that deals withEmbedded System
  12. 12. Importance of EmbeddedSoftwareand Embedded Processors“... the New York Times has estimated that theaverage American comes into contact with about 60micro-processors every day....” [Camposano, 1996]Latest top-level BMWs contain over 100microprocessors [Personal communication]
  13. 13. 16 It is estimated that each year embedded software iswritten five times as much as regular software The vast majority of CPU-chips produced world-widetoday are used in the embedded market ... ; only a smallportion of CPUs is applied in PCs ... the number of software-constructors of EmbeddedSystems will rise from 2 million in 1994 to 10 million in2012;... the number of constructors employed by software-producers merely rises from 0.6 million to 1.1 million.[Department of Trade and Industry/ IDC Benelux BV: Embedded softwareresearch in the Netherlands. Analysis and results, 1997(according to: www.scintilla.utwente.nl/shintabi/engels/thema_text.html)]Conclusion
