Question 1) Why cannot hard real time systems use rollback for error detection/recovery?
Question 2) Describe Time token protocol in detail with a suitable flow chart.
Question 3) Why is the polling latency typically faster than interrupt latency?
Question 4) Mention the needs of distinctive the step system integration involved in real-time system design process.
Question 5) Write down the benefits of using the general-purpose processor in case of designing a real-time system? In this context, explain the benefits of using the standard single-purpose processor instead of using the general-purpose one.
Question 6) What do you understand by real-time system design process? Why is it significant? Specify the requirements involved in real-time system design process.
Question 7) By giving suitable state diagram of the fault classes, describe the causes for various kinds of faults and their remedies. What are the different methods of concurrency control? Which of these may lead to deadlock and explain why.
Question 8) Assume that a system is in an unsafe state. Demonstrate that it is possible for the processes to complete their execution without entering a deadlock state.
