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

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 Ning WengECE 4242

3. Technology Trends Computation Connectivity Storage Sensing Ning WengECE 4243

4. Computation: Morre’s Law Ning WengECE 4244

5. Connectivity: Bandwidth Ning WengECE 4245 Global BW Wireless BW by Applications

6. Unit for BW Gigabyte : GB, power of 9 Terabyte: TB, power of 12 Petabyte: PB, power of 15 Exabyte: EB: power of 18 Ning WengECE 4246

7. Connectivity: Devices & Cost Ning WengECE 4247 Interne of Things: 1 Trillion year 2013, most of them are embedded Internet access cost: fairly stable though BW rate increasing

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 Ning WengECE 4248

9. Issues Energy Security Health Ning WengECE 4249

10. Energy Ning WengECE 42410

11. Security Reasons: Information value and inexpensive to duplicate, store and transfer Attacks: Malicious and misuse Ning WengECE 42411 Courtesy of Trusted Computing Group

12. Challenges and Uncertainties Open systems ─ Close system slow the innovation Internet Access Net Neutrality Privacy Successful commercialization Ning WengECE 42412
