Using the 8bit Unsigned binary number system perform the fol

Using the 8-bit, Unsigned binary number system, perform the following addition and subtraction problems. Clearly indicate how you checked for an overflow condition and the result of that check.

Solution

1 1 1 0 0 0 1 0

0 1 1 1 1 0 0 1 +

-----------------------

1 0 1 0 1 1 0 1 1

------------------------

Here number of bits in result is 9 bits. That 9th bit is 1. So overflow occurs

Overflow flag will be set to 1.

1 1 1 0 0 0 1 0

0 1 1 1 1 0 0 1 -

---------------------

0 1 1 0 1 0 0 1

--------------------

Here no 9th bit. Also result of subtraaction never overflow
