Q3 (Covers Block 3)

(a) A computer has a single processor of one core. It has 16 general purpose registers. The machine has 64 KB RAM. The size of each register and memory word is 32 bits. The computer uses fixed length instructions of size 32 bits each. An instruction of the machine can have two operands – the first operand is a memory operand and the second operand is a register operand (register operand can be a general purpose register). Memory operand uses direct addressing, however, register operand use either register direct or register indirect addressing. (Please note that if register operand uses register indirect addressing, then the stated register contains the address of the operand in the memory.) An instruction of a machine consists of bits for operation code, one bit for addressing mode, bits for one memory operand and bits for one register operand. The machine has about 200 different operation codes. The addressing mode bits specifies addressing mode as:

Addressing mode bit	Register Operand	Memory Operand

0	Indirect	Direct

1	Direct	Direct

The special purpose registers, which are other than general purpose registers, are - Program Counter (PC), Memory Address Register (MAR), Data Register (DR) and Flag registers (FR). The First register of the general purpose registers can be used as Accumulator Register. The size of Integer operands on the machine may be assumed to be equal to the size of accumulator register. In order to execute instructions the machine has another special register

(5 Marks)

called Instruction Register (IR) of size 32 bits, as each instruction is of this size. Perform the following tasks for the machine. (Make and state suitable assumptions, if any.)

are unused for this machine. Explain your design of instruction format. (3 Marks)

(ii) List at least two valid instructions, and put some valid data values in registers and memory locations, and demonstrate examples of different addressing modes for this

machine. (2 Marks)

(iii) Assuming that the instructions are first fetched to Instruction Register (IR), memory operand is brought to DR register, and result of an operation is stored in the Accumulator register; write and explain the sequence of micro-operations that are required to fetch and

execute an instruction, which performs addition of two operands having addressing mode bits as 1. Please note that one of the operand is direct memory operand and second is an Register Operand. Make and state suitable assumptions, if any.

(b) Assume that you have a machine as shown in section 3.2.2 of Block 3 having the micro-operations as given in Figure 10 on page 62 of Block 3. Consider that R1 and R2 both are 8

bit registers and contains 01010101 and 10011010 respectively. What will be the values of select inputs, carry-in input and result of operation (including carry out bit) if the following micro-operations are performed? (For each micro-operation you may assume the initial

value of R1 and R2 as given above) (2 Marks)

This assignment has seven questions. Answer all questions. Please go through the guidelines regarding assignments given in the Programme Guide for the format of presentation.

Q1:

Read the passage below and answer the questions that follow:

Whatever the type of job interview a walk-in, a telephone interview or a regular in-person job interview, preparation is the key. It is important that you keep yourself in a state of high motivation and readiness, making optimum use of your time to equip yourself to excel. Here are

a few things you’d like to do for sure, by way of preparation.

You are certain to be asked specific questions about your potential employer, so make sure you’ve done your homework on company information like company history, recent performance, their last year's profits and latest product launches. Nothing is as disappointing as when a candidate shows enthusiasm and then doesn’t even know the most basic facts and figures about the company. So, where can you find all this information? The most likely place is the Internet. A visit to the company website could help you get all the vital statistics, including products and services as well as a feel of the company culture. You must also check out the annual report and look for a press or company news page. Put their name into a search engine to see if they’ve had any recent interesting stories written about them. It is also advisable to tap industry sources, trade journals, newspapers and other business publications to give you good background knowledge of the industry as well as the company.

Talk to people who work in the company or in similar companies / areas to gather as much information as you can about the nature of work, responsibilities, work culture and work requirements.

For the interview, you need to know your CV inside out. Go through your CV carefully and make notes on how you will elaborate or illustrate what you have stated. You need to be ready with examples from your experience to be able to substantiate all the claims you have made. Try to relate specific areas of your CV back to the job description. It will make it clear to the interviewer why they should hire you. Also go through the copy of your application carefully before the interview. The interview panel is likely to ask specific questions about it.

Going for a job interview is no different from going for an exam. It is important that you go well prepared and confident so that you can field any question that is put to you.

Before the Interview

Apart from finding out about the company and being thorough with your CV, it would be helpful to follow these tips:

• Make a rational assessment of yourself before you go for the interview. Know your strengths and weaknesses.

• Review your skills and abilities.

• Have a mock interview with a friend based on the common interview questions you’re likely to face.

• If you are asked to bring certificates, references, etc, get them ready well in advance to avoid having to chase around them on the morning of the big day.

• If you have filled up a statement of purpose as part of the application, be ready for some probing questions based on this.

• Be sure you know the time, date and location of the interview.

• Decide how you will get there and when you need to set off to arrive in good time, anticipating any delays. Visit the place once beforehand if possible.

• If you look good, you tend to feel good too. Avoid any last minute panic by preparing what you’re going to wear the night before.

• Don’t go into the interview with lots of baggage - psychological or physical. Take the bare minimum with you so you can concentrate on the interview, and nothing else.

• Prepare at least 5 questions that you would like to ask the panel about the company or your job. You don’t have to ask them all. See for yourself what is most appropriate to ask during the interview.

(a)	What should be your state of mind when getting ready for a job interview?	(2 Marks)
(b)	Why do you need to do adequate homework about the company where you	(2 Marks)
	have been called for an interview?
(c)	What sort of information can you get about the company from the internet?	(2 Marks)

Design and create four web pages for the website of the University namely, Home, Programme List, Registration Form and Important Dates, having the following features:

For consistency, every web page of the website should consists of three basic divisions –

Header – This division should be of the same for all the four web pages and should display name and logo of the University. This division should be in different background colour.

Options - This division should be same in every web page and should be towards the left in every web page. It should contain links to all the web pages viz. Home, Programme List, Registration and Important Dates.

Data - This division should display the basic information as given below. The web pages that you are designing should differ in this Division only.

The Data division of the different pages should be as under:

• Home page should include Welcome message, the aims and objectives of the University and strengths of the University

• Programme List page should display information about the programmes of the University in a tabular form. The table should contain Programme Code, Programme name, duration, Medium of instruction, eligibility criteria and total fee of the Programme.

• Registration page should contain a form which should have fields - name of the student, email id, phone, qualification of student, programme being registered, and a Submit button. You should also write the JavaScript code to verify that all the fields are filled by the person registering for the University.

• Important Dates page should display the start date of admission, the last date of admission and start date of commencement of programme, using an unordered list.

Section 2: Assembly Language Programming Lab

Q1.

a) Design a two bit down counter circuit that counts from 3 to 0. It should have states 11, 10, 01, and 00. The initial state of the counter may be assumed to be 11. The counter will

be in following successive states: 11, 10, 01, 00, 11, 10, 01, 00, 11,... Use J-K flip flop to design the circuit. You must design the circuit using state transition diagram and

Karnaugh's maps. (5 Marks)

(5 Marks)

b) Write and run a 8086 Assembly language program that converts a three digit ASCII number stored in three consecutive byte locations in the memory, into a binary number.

The output should be stored in DX register. For example, if three consecutive byte locations contain '345' (please note they are three ASCII digits), then the DX should get binary equivalent of decimal number 543, which is (0000 0010 0001 1111)2. This binary

value will be stored in DX register.

c) Write and run (using appropriate calling program) a near procedure in 8086 assembly language, which is passed a single parameter by the calling program. The procedure checks if the input parameter has a value zero or not. If the value of input parameter is

zero then procedure/program is terminated, otherwise a value of 1 is returned to the calling program, which then continue to execute the remaining program. Make and state

suitable assumptions, if any. (5 Marks)

d) Write and run a 8086 assembly language program that finds the sum of first N natural numbers. The value of N is input to the assembly program. The sum is stored in DX
