Total No. of Questions : 12] P962 [Total No. of Pages : 3 [3664]-360 B.E. - (I.T.) REAL TIME SYSTEM (Elective - II) (2003 Course) Time : 3 Hours] [Max. Marks : 100 Instructions to the candidates: 1) 2) 3) 4) 5) Answer 3 questions from Section I and 3 questions from Section II. Answers to the two sections should be written in separate books. Neat diagrams must be drawn wherever necessary. Figures to the right indicate full marks. Assume suitable data, if necessary. SECTION - I Q1) a) Draw neat block diagram of Real Time System (RTS) and explain its different components. [8] b) Explain the following properties of good performance measure. i) Efficient encoding. ii) Object basis for ranking. iii) Objective optimization criteria. iv) Verifiable facts. OR [8] Q2) a) What is performability of RTS? In what way it is different then traditional measure of performance? [8] b) In a real-time-system, how do the following factor affect the estimation of program run time? i) ii) Analysis of source code. Use of cache. [8] Q3) a) Explain the classification of uniprocessor scheduling algorithm. With the help of suitable example explain the RM scheduling algorithm. [10] b) Write short note on (Any two) i) The buddy strategy. ii) MOS (Myopic Offline Scheduling) algorithm. iii) IRIS (Increase Reward Increase Service) OR [8] P.T.O. Q4) a) Explain the preemptive Earliest Deadline algorithm with the help of suitable example. In what way preemptive-Earliest Deadline First algorithm (EPF) is different then Rate Monotonic Scheduling algorithm (RM)? [10] b) Write short note on (Any two) i) Focused Addressing and Bidding algorithm. [FAB] ii) Fault tolerant scheduling algorithm. iii) Disk scheduling algorithm. [8] Q5) a) Mention the desired characteristics of real time language. [8] b) Describe the priority inheritance protocol. Give an example to show this protocol can lead to deadlock. [8] OR Q6) a) State the features of hard real time database system MDARTS. Illustrate with the help of neat diagram how shared memory is encapsulated using the object oriented approach. [10] b) Describe the Adaptive Earliest Deadline (AED) algorithm used in transaction priorities. [6] SECTION - II Q7) a) Explain Virtual Time Carrier Sensed Multiple Access (VTCSMA) algorithm with flow chart. Draw the VCRC trajectory for example for n = 2. [10] b) Describe the stop and GO multihop protocol and comment on its performance. [8] OR Q8) a) Discuss the window protocol with suitable example. Discuss the performance of this algorithm. Where is the contention protocol most suitable. [10] b) Describe the Timed Token protocol. Why this protocol is attractive for [8] RTS. Q9) a) Write short notes on : i) RT Linux. ii) VX-Work. [8] b) Describe the following capabilities of a real-time operating system. [8] i) Split Interrupt Handling. ii) Memory management through virtual memory mapping and memory locking. [3664]-360 2 OR Q10) a) Write short note on the following mechanism Present in a real-time operating system. [8] i) Time Services. ii) Scheduling Mechanism. b) Discuss the real time extension of Linux operating system. [8] Q11) a) Illustrate with the help of neat diagram the implementation of N-Modular [8] Redundancy. b) Describe the following software redundancy method. i) N-version Programming. ii) Recovery Block approach. [8] OR Q12) a) Describe the 3-type of voters in cases where an approximate agreement is required to achieve hardware redundancy through voting and consensus. [8] b) Explain the Byzantine s algorithm for fault tolerance with an example. Also specify the interactive consistency condition. [8] [3664]-360 3
