Course Code : MCS 202

Course Title : Computer Organisation

Assignment Number : PGDCA(1)/202/Assign/2022

Maximum Marks : 100

Weightage : 25%

There are four questions in this assignment, which carries 80 marks. Rest 20 marks are for viva voce. You may use illustrations and diagrams to enhance the explanations. Please go through the guidelines regarding assignments given in the Programme Guide for the format of presentation. Answer to each part of the question should be confined to about 300 words. Make suitable assumption, if any.

Question 1:

2 marks each × 10 parts =20 Marks

(a) Explain the Harvard architecture with the help of a diagram.

(b) Explain how Harvard architecture is different from the von Neumann Architecture.

(c) Perform the following conversion of numbers:

(i) Decimal (8734595454)10 to binary and hexadecimal.

(iii) String “ASCII to UTF 16” to UTF 8

(iv) Octal (6703421)O to Decimal

(d) Simplify the following function using K-map: F(A, B, C, D) = Σ (0, 1, 3, 4, 5, 6, 7, 14, 15). Draw the circuit for the function using NAND gates.

(e) Consider the Adder-Subtractor circuit given in Unit 3 of Block 1. Explain how this circuit will perform subtraction (A-B), if the value of A is 0111 and B is 0011. You must list all the bit values including Cin and Cout and overflow condition, if any.

(f) Explain the functioning of a 4´1 multiplexer. You should draw its truth table and explain its logic diagram with the help of an example input.

(g) Assume that a source data value 0011 was received at a destination as 0001. Show how Hamming's Error-Correcting code will be appended to source data, so this error of one bit is identified and corrected at the destination. You may assume that error while transmission occurs only in the source data and not in the code.

(h) Explain functioning of JK flip flop with the help of a logic diagram and characteristic table. Also draw and explain the excitation table of this flip-flop.

(i) Explain the functioning of a 3-bit Synchronous counter with the help of a diagram.

(j) Represent (-54.5)10 and (0.0625)10 in IEEE 754 single precision format.

Question 2:

4 marks each × 5 parts =20 Marks

(a) What is SRAM? How is it different to DRAM? Define the access time of a Hard disk. How is access time of hard disk is computed? Explain with the help of an example. Also differentiate between CLV and CAV types of disk organisation.

(b) Explain the following cache to main memory mapping schemes with the help of an example and suitable diagram.

(i) Associative cache mapping

(ii) Two way set associative cache mapping

(c) What is an Input/Output processor? Why is it needed? What are the functional similarities and differences between I/O processor and DMA module?

(d) Explain the concept of Programmed I/O and Interrupt driven I/O techniques. How are these two techniques different? In what situation, would you use the Interrupt driven I/O?

(e) Explain the technology of two Input and two output devices in details.

Question 3:

4 marks each × 5 parts =20 Marks

(a) What are different types of instruction supported by a computer? Explain at least two instructions of each type.

(b) Using a diagram showing content of sample memory and registers, explain the following addressing modes – Register Indirect addressing, Relative addressing, Index addressing and Base register addressing. (You should show instruction, operands and addresses in the diagram.)

(c) What is a micro-operation? Explain different types of micro-operations with the help of one example each.

(d) Explain the design of a simple ALU and micro-operations supported by it.

(e) What is the need of RISC? How are RISC processors different than the CISC processors? Explain with the help of a diagram, how the large register file in RISC is useful for procedure calls.

Question 4:

5 marks each × 4 parts =20 Marks

(a) Explain different set of registers used in 8086 micro-processor. Also explain the utility of all the segment registers with the help of examples.

(b) What is the use of IVT? Explain with the help of a diagram. Write a program using 8086 assembly language to output a string “Use assembly program for speed”.

(c) Write a program in 8086 assembly language, which converts a two-digit ASCII number to a packed BCD number. Explain each step of the program.

(d) List the characteristics of the following:

(i) Multiprocessors

(ii) Multiport memory

(iii) Inter processor communication and synchronization

(iv) Multi-core processors

POST GRADUATE DIPLOMA IN AUDIO PROGRAMME PRODUCTION P.G. Diploma Programmes PGDCA ASSIGNMENTS

Dear Learner,

You have to submit one assignment in each course, i.e. MCS 202, MCSL 204. All these are Tutor Marked Assignments (TMAs). Before attempting the assignments, please read the instructions provided in the Programme Guide carefully.

Kindly note, you have to submit these assignments to the Coordinator of your Study Centre within the stipulated time for being eligible to appear in the term-end examination. You must mention your Enrolment Number, Name, Address, Assignment Code and Study Centre Code on the first page of the assignment. You must obtain a receipt from the Study Centre for the assignments submitted and retain it. Keep photocopies of the assignments with you.

After evaluation, the assignments have to be returned to you by the Study Centre. Please insist on this and keep a record with you. The marks obtained by you will be sent by the Study Centre to the Student Evaluation Division at IGNOU, New Delhi.

Guidelines for Doing Assignments

There are five questions in each assignment, all carry equal marks. Attempt all the questions in not more than 500 words (each). You will find it useful to keep the following points in mind:

Planning: Read the assignments carefully. Go through the units on which they are based, make some points regarding each question and then rearrange them in a logical order

Organization and Presentation: Be analytical in your selection of the information for your answer. Give adequate attention to the introduction and the conclusion. Make sure that your answer is logical and coherent; has a proper flow of information.
