1.in assembler relocatable code generated by ...!!??

asn: indirect addressing

2. int v,u;

while(v != 0)

{

t = v % u;

v = u;

u = t;

}

find the time complexity of the above program.

3. x is passed by reference, y passed by value.

x = 3, y = 2;

foo(x, y)

var integer x, y;

{

x = x + 2;

y = y + 3;

}

main()

{

x = 5;

y = 5;

foo(x, y);

print (x, y);

}

output of the above pseudo code.

4. how many flip flops you require for modulo 19 counter.

5. ring counter's initial state is 01000. after how many clock cylces will

it return to the initial state.

6. some boolesn expression of the form x'y'z' + yz + .. ( something like

this) find the simplified expression

7. given 6 bit mantissa in 2s complement form and 4 bit exponent is in

excess-4 form in a floating point representation, find the number

ans -(something) * ( 2 to the power 3)

8. A signed no is stored in 10-bit register, what is the max and min

possible value of the number.

1 feet from the bottom. what is the min distance reqd for the spider to

crawl to the fly.

7. A man while going dowm in a escalator(which is miving down) takes 50

steps to reach down and while going up takes 125 steps. If he goes 5 times

faster upwards than downwards. What will be the total no of steps if the

escalator werent moving.

boxes are negative edge triggered flip flops and 'not' and 'and' are

gates. What is this figure.

ans- modulo-5

10.

It is difficult to draw a figure but another question was in which some

NAND and OR gates were given.

ans - Z = true.
