Question 1.
What does overflow mean in arithmetic operations?
Show hintHide hint
Think about the limits set by the number of bits in representation.
Question 2.
Give an example of a scenario where overflow might occur.
Show hintHide hint
What happens if you add two maximum numbers in a system?
3Question 3.
What happens when two negative numbers are added in signed arithmetic and the result is interpreted as positive?
- Overflow occurs
- Carry occurs
- No overflow
Show hintHide hint
Consider the sign bit in the result.
4Question 4.
The carry flag primarily applies to which type of arithmetic?
- Signed Arithmetic
- Unsigned Arithmetic
- Both
Show hintHide hint
Reflect on how negative numbers influence carry.
Question 5.
You are tasked with designing a system that involves adding two 4-bit signed integers. Explain how you would handle potential overflow in your calculations.
Show hintHide hint
Consider what conditions will cause the overflow to trigger.
Question 6.
In an unsigned arithmetic system, what happens when you add two maximum values (e.g., 15 + 1)? Explain the results and the implications in a larger computation.
