1. Design a soft real time system for a car driving video game. Identify the basic tasks required and implement the same with an appropriate scheduling algorithm. (model, algorithm and Cheddar implementation)
Explain what type of system it is i.e. either HARD /SOFT OR FIRM and justify your answer.
Also mention what type of scheduling algorithm can be used and justify your answer.
Also say whether it is online or offline scheduler and justify your answer.

2. a) Explain the problems that might arise if hard-real time tasks are made to share critical resources among themselves using traditional operating system primitives such as semaphores or monitors. Briefly explain how these problems can be overcome.
b) Write short notes on effects of resource contention and resource access control.
Design a real time system to track telephone calls. (model, algorithm and Cheddar implementation)
identify whether choclate vending machine is hard/soft and open/closed real time system
Q)Develop a software model for a simple login based website to maintain recipes of favourite dishes (name, ingredients, recipe details) and use database to store login information and user should be able to login and create new receipes and also add functionality to search, classify (south indian/north indian) and add a view counter to signify how many times it is viewed.
Requried:
The Assignment comprise of: Use case, Domain Model and Domain Class Diagrams, Object Diagrams, Component Diagrams, Composite Structure Diagrams, Deployment Diagrams, Package Diagrams; Various Types of Interaction Diagrams (Sequence Diagrams, Communication Diagrams, Interaction Overview Diagrams), State Diagrams, Activity Diagrams, Use Case Diagrams, Collaboration Diagrams, Timing Diagrams wherever required.
There are several different algorithms for scheduling periodic tasks on a uniprocessor system.
Those algorithms fall into two broad categories: clockdriven and priority-driven. Discuss the
relative advantages and disadvantages of the two categories of algorithm, explaining when it
is appropriate to use a clockdriven scheduler and when one would expect to use a priority-driven scheduler.
Design a real time system for raising an emergency alert in a building. The hazards could be fire,
accidents in foundry, current shock, etc. . (model, algorithm and Cheddar implementation).

Design a hard real time system in Boiler temperature management system. The system should check the temperature and intimate the operator if a threshold has been exceeded to start a coolant. (model, algorithm and Cheddar implementation)
Design a soft real time system for a vending machine that provides chocolates. Identify the different tasks and implement the same with a suitable scheduling algorithm.
