  1. ECE 424 Embedded Systems Design Lecture 2: Attributes of Embedded Systems Now NingWeng

  2. ES Future Landscape We know what now, let us look forward • Technology trends • Issues, applications and initiatives • Challenges and uncertainties • Nontechnical but likely substantial impact on ES Prepare not Simply predict ECE 424

  3. Technology Trends • Computation • Connectivity • Storage • Sensing ECE 424

  4. Computation: Morre’s Law ECE 424

  5. Connectivity: Bandwidth Global BW Wireless BW by Applications ECE 424

  6. Unit for BW • Gigabyte : GB, power of 9 • Terabyte: TB, power of 12 • Petabyte: PB, power of 15 • Exabyte: EB: power of 18 ECE 424

  7. Connectivity: Devices & Cost Interne of Things: 1 Trillion year 2013, most of them are embedded Internet access cost: fairly stable though BW rate increasing ECE 424

  8. Storage • Nonvolatile memory • Magnetic hard disk drive • Cost per unit storage halves per 15 months • Motors: slower in orders of magnitude than electronic • Flash memory • CMOS tecnology • Up to 10 GV, good for embedded devices ECE 424

  9. Issues • Energy • Security • Health ECE 424

  10. Energy ECE 424

  11. Security • Reasons: Information value and inexpensive to duplicate, store and transfer • Attacks: Malicious and misuse Courtesy of Trusted Computing Group ECE 424

  12. Challenges and Uncertainties • Open systems • Close system slow the innovation • Internet Access • Net Neutrality • Privacy • Successful commercialization ECE 424

  13. For Next Class • Get textbook • Read Chapter 13 for Qt App. framework ECE 424
