After seeing the general course outline, are there any areas or topics you would like to see covered?

18. Why Embedded Systems Are Different
Embedded systems are dedicated to specific tasks
Embedded systems are supported by a wide array of processors

19. Why Embedded Systems Are Different
Embedded systems are usually cost sensitive
Embedded systems have real-time constraints
Time-sensitive constraints – soft real-time
Time-critical constraints – hard real-time

20. Why Embedded Systems Are Different
If an embedded system is using an operating system at all, it is most likely using a real-time operating system (RTOS)
The implications of software failure are much more severe in embedded systems
Hardware assists for failure recovery – watchdog timer

21. Why Embedded Systems Are Different
Embedded systems often have power constraints
Embedded systems often must operate under extreme environmental conditions

22. Why Embedded Systems Are Different
Embedded systems have far fewer system resources than desktop systems
Embedded systems often store all their object code in ROM

23. Why Embedded Systems Are Different
Embedded systems require specialized tools and methods to be efficiently designed
Embedded microprocessors often have dedicated debugging circuitry

24. Challenges of Embedded Software
Throughput
Response Times
Testability
Debugability
Reliability

25. Challenges of Embedded Software
Memory Space
Program Installation
Power Consumption
Processor Hogs
Cost

26. The Embedded Design Life Cycle
