Problem 1
Using examples, explain why real-time systems usually have to be implemented using concurrent processes.
Problem 2
Identify possible stimuli and the expected responses for an embedded system that controls a home refrigerator or a domestic washing machine.
Problem 4
Explain why an object-oriented approach to software development may not be suitable for real-time systems.
Problem 5
Show how the Environmental Control pattern could be used as the basis of the design of a system to control the temperature in a greenhouse. The temperature should be between 10 and 30 degrees Celsius. If it falls below 10 degrees, the heating system should be switched on; if it goes above 30 , the windows should be automatically opened.
Problem 10
Why are general-purpose operating systems, such as Linux or Windows, not suitable as real-time system platforms? Use your experience of using a general-purpose system to help answer this question.
