  1. Directions in Embedded Systems • A combination of computer hardware and software, and perhaps additional mechanical or other parts, designed to perform a dedicated function. • http://www.netrino.com/Publications/Glossary/ Electrical & Computer Engineering - Embedded Systems 1

  2. Electrical & Computer Engineering - Embedded Systems 2

  3. Microspace EBX - http://www.adlogic-pc104.com/products/cpu/sbc/datasheets/msebx-p5-p3.pdf Electrical & Computer Engineering - Embedded Systems 3

  4. Directions in Embedded Systems • "By definition, embedded systems are a mishmash of nonstandard stuff, ... with all sorts of data flowing all over the place” • http://www.eetimes.com/news/98/1008news/industry.html Electrical & Computer Engineering - Embedded Systems 4

  5. Directions in Embedded Systems • Examples can be found within cars; portable telephones; microwave ovens; CD players; telephone answering machines and many, many more things that we encounter daily. Electrical & Computer Engineering - Embedded Systems 5

  6. Directions in Embedded Systems • The one factor that characterises embedded systems is that they are all different! • one of the least important costs involved in the production of a microcomputer-based system is actually the cost of the micro-processor itself. Electrical & Computer Engineering - Embedded Systems 6

  7. Directions in Embedded Systems from David Tennenhouse - Proactive Computing Comm. ACM, May 2000 Electrical & Computer Engineering - Embedded Systems 7

  8. Directions in Embedded Systems • Personal Computing • Wearable Computing • Proactive Computing • Pervasive Computing • Amorphous Computing • Ubiquitous Computing • Ambient Intelligence from David Tennenhouse - Proactive Computing Comm. ACM, May 2000 Electrical & Computer Engineering - Embedded Systems 8

  9. Ubiquitous Computing Ubiquitous computing names the third wave in computing, just now beginning. First were mainframes, each shared by lots of people. Now we are in the personal computing era, person and machine staring uneasily at each other across the desktop. Next comes ubiquitous computing, or the age of calm technology, when technology recedes into the background of our lives. Alan Kay of Apple calls this "Third Paradigm" computing. http://nano.xerox.com/hypertext/weiser/UbiHome.html Electrical & Computer Engineering - Embedded Systems 9

  10. Ambient Intelligence • electronic environments that are sensitive and responsive to the presence of people Electrical & Computer Engineering - Embedded Systems 10

  11. Ambient Intelligence • Ambient Intelligence = Ubiquitous Computing + Intelligent Social User Interfaces • Distribution • Transparency • Ubiquity Electrical & Computer Engineering - Embedded Systems 11

  12. Ambient Intelligence Mark Weiser - User Interface, Systems, and Technologies (UIST) Conference, November, 1994 Electrical & Computer Engineering - Embedded Systems 12

  13. Enabling Technologies - OS • embedded-Linux wristwatch (IBM) • communicates wirelessly with PCs, cell phones, and other wireless-enabled devices • capable of viewing condensed e-mail messages and receive pager-like messages. • Operating system ... what operating system? • e.g. embedded LINUX • many believe embedded-Linux devices will outnumber Palm devices in two years. • mainly due to lack of an OS licensing fee Electrical & Computer Engineering - Embedded Systems 13

  14. Enabling Technologies - Languages • Java • PersonalJava™, EmbeddedJava™, Java Card™ • C-based • Embedded C, C++, C# (?) • Assembler (?) • HDLs • VHDL, Verilog, SystemC Electrical & Computer Engineering - Embedded Systems 14

  24. A Dissenting View: "Mobile wireless computers are like mobile pipeless bathrooms--portapotties. They will be common on vehicles, construction sites, and rock concerts. My advice is to wire up your home and stay there. Use information highways to let you stay home with your kids, not to make you more of a road warrior." Bob Metcalfe, inventor of Ethernet Byte Predictions for the Year 2000 http://www.byte.com/art/9509/sec7/art17.htm Electrical & Computer Engineering - Embedded Systems 24
