Question

**Given two numbers A = 0111 1111 and B = 0111 1111. Add
them and find the correct option.**

a) There is unsigned overflow but no signed overflow.

b) There is signed overflow but not unsigned overflow.

c) There is signed as well as unsigned overflow.

d) There is no overflow.

**with explanation.**

Answer #1

Ans

b) There is signed overflow but not unsigned overflow

.

.

In signed numbers first bit is sign bit. Here add results in 11111110 the magnitude gets into sign bit and sets the sign bit . Overflow flag get set. Signed overflow occur when result goes out of 7 bits

.

.

If unsigned numbers are used all bits represent magnitude. so addition does not lead any overflow. The result is a valid unsigned number. No carry flag is set which indicate unsigned overflow. It occurs if result goes out of 8 bits.

If any doubt ask in the comments.

Please appreciate the work by giving a thumbs up.

Convert each of following numbers to Hexadecimal numbers,
showing all steps.
a. (1111 0111)2
b. (1010 1010 1010)2
c. (777) 8
d. (443) 8
e. (998)10
f. (1066)10

Suppose A and B are signed numbers, find the
logic expression of the overflow flag when A and B are added. R =
result. (Hint: Recall that overflow happens to signed addition
if and only if 1) adding two positives and getting a
negative, or 2) adding two negatives and getting a
positive.)
A =
a31a30a30…a2a1a0
B =
b31b30b30…b2b1b0
R =
r31r30r30…r2r1r0

A and B are two 8-bit 2’s complement numbers. The result of
A & B is 10011000
and the result of
A ^ B is 00100110.
(a) What is the sum
A + B
expressed in 8-bit two’s complement notation (use 1s and 0s,
e.g. 10100101)?
Will the carry ﬂag be set?
Will the overflow ﬂag be set?
