1) We say that in embedded operating systems, if the highest-priority user thread is executing when a high-priority interrupt occurs, most operating systems will continue to process the user thread and keep the interrupt in queue until processing is completed. Under what circumstances would this be and would this not be a problem? Give an example of each.

2) Present arguments for and against the use of dynamic memory in embedded systems. Should it be banned for use under all circumstances? Why or why not?

3) In the sidebar concerning watchdog timer engineering decisions, we stated that rebooting an embedded system typically takes less time than rebooting a personal computer. Why do you think that this is so?

4) What does the "reduced" in reduced instruction set computer really mean?
