NPTEL Real-Time Systems Assignment

ABOUT THE COURSE :

The rapid growth of applications deploying real-time technologies has been matched by the evolutionary growth of the underlying technologies supporting the development of real-time systems. In this course, some of the core technologies used in developing real-time systems will be discussed. Mainly, the software issues related to real-time systems will be discussed, keeping the hardware discussions to bare minimum. The software issues that will be addressed are quite expansive, including the operating system and program development issues, the networking and database issues, etc. Also, some of the popular commercial real-time operating systems and their important features will be discussed in this course.

This course can have Associate in Nursing unproctored programming communication conjointly excluding the Proctored communication, please check announcement section for date and time. The programming communication can have a weightage of twenty fifth towards the ultimate score.

Final score = Assignment score + Unproctored programming exam score + Proctored Exam score
  • Assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
  • ( All assignments in a particular week will be counted towards final scoring – quizzes and programming assignments). 
  • Unproctored programming exam score = 25% of the average scores obtained as part of Unproctored programming exam – out of 100
  • Proctored Exam score =50% of the proctored certification exam score out of 100
YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF ASSIGNMENT SCORE >=10/25 AND
UNPROCTORED PROGRAMMING EXAM SCORE >=10/25 AND PROCTORED EXAM SCORE >= 20/50. 
If any one of the 3 criteria is not met, you will not be eligible for the certificate even if the Final score >= 40/100.

Which of the following are FALSE concerning a priority exchange server?
a.It serves a set of aperiodic tasks
b.It is an aperiodic task
c.It has much better response time for aperiodic tasks compared to polling server.
d.It preserves its execution time till the end of its period, if no aperiodic tasks are ready.
e.It has much better response time for aperiodic tasks compared to deferable server.
f. When the priority exchange server is invoked by the scheduler, if no aperiodic tasks are ready, it exchanges its priority with a lower priority task that is ready.
g. Its implementation is simpler than a deferable server Consider a set of six periodic real-time tasks that are to be run on a uniprocessor-based embedded system using a rate monotonic scheduler. However, the embedded operating system supports only four priority levels? Which one of the following is the priority assignment using the uniform scheme? Assume pri(Ti) is the priority of Ti and priority level 1 is the highest priority and 4 is the lowest priority.

b.It is used for assign priority to some tasks with very short periods have very high criticality and to perform schedulability analysis in this situation
c.It essentially enables scheduling sporadic tasks by a rate monotonic scheduler by logically transforming those tasks into periodic tasks
d.It essentially enables scheduling aperiodic tasks by a rate monotonic scheduler by logically transforming those tasks into periodic tasks
