Date: July 1997
------------------------------------------------------------------------------
This paper have two sections
each paper contains 10 questions each.
-----------------------------------------------------------------------------
1) abcD+abcd+aBCd+aBCD
then the simplified
function is
( Capital letters are
copliments of corresponding letters
A=compliment of a)
[a] a [b] ab
[c] abc [d] a(bc)* [e] mone
(bc)*=compliment of bc
Ans: e
-------------------------------------
2) A 12 address lines maps to the memory of
[a] 1k bytes [b] 0.5k bytes [c] 2k bytes [d] none
Ans: b
----------------------------------------
3) In a processor these are 120 instructions . Bits needed to
impliment
this instructions
[a] 6 [b] 7
[c] 10 [d] none
Ans: b
-----------------------------------------
4) In 8085 microprocessor READY signal does.which of the
following
is incorrect
statements
[a]It is input to the
microprocessor
[b] It sequences the
instructions
Ans : b
----------------------------------------
5) Return address will be returned by function to
[a] Pushes to the stack
by call
Ans : a
------------------------------------------
6)
n=7623
{
temp=n/10;
result=temp*10+
result;
n=n/10
}
Ans : 3267
----------------------------------------------
7) If A>B then
F=F(G);
else B>C then
F=G(G);
in this , for 75%
times A>B and 25% times B>C then,is 10000
instructions
are there ,then the
ratio of F to G
[a] 7500:2500 [b] 7500:625 [c] 7500:625 if
a=b=c else
7500:2500
Ans : b
--------------------------------------------------
8) In a compiler there is 36 bit for a word and to store a
character 8bits are needed. IN this to store
a character two words
are appended .Then for storing a K
characters string,
How many words are
needed.
[a] 2k/9 [b] (2k+8)/9 [c] (k+8)/9 [d] 2*(k+8)/9
[e] none
Ans: b
---------------------------------------------------------
9) C program code
int zap(int n)
{
if(n<=1)then
zap=1;
else zap=zap(n-3)+zap(n-1);
}
then the call zap(6)
gives the values of zap
[a] 8 [b]
9 [c] 6 [d]
12 [e] 15
Ans: b
---------------------------------------------------------------
PART-B
-------
1) Virtual memory size depends on
[a] address lines [b] data bus
[c] disc space [d] a & c [e] none
Ans : a
-----------------------------------------------
2) Critical section is
[a]
[b] statements which
are accessing shared resourses
Ans : b
-------------------------------------------------
3) load a
mul a
store t1
load b
mul b
store t2
mul t2
add t1
then the content in
accumulator is
Ans : a**2+b**4
---------------------------------------------------
4) question (3) in old paper
5) q(4) in old paper
6) question (7) in old paper
7) q(9) in old paper
