Question 1.
What is the primary function of the ALU?
Show hintHide hint
Think about the operations you often do in math.
Question 2.
What does the term 'trade-off' refer to in CPU design?
Show hintHide hint
Consider what you give up for a potential gain.
3Question 3.
What is the primary role of the ALU in a CPU?
- Data storage
- Arithmetic and logic operations
- Input and output management
Show hintHide hint
Think about the types of calculations a CPU does.
4Question 4.
True or False: ALUs can only perform addition and subtraction.
- True
- False
Show hintHide hint
Remember the logical operations as well.
Question 5.
Design a simplified ALU that can execute at least three operations (addition, subtraction, and multiplication). Discuss the hardware requirements and any potential trade-offs involved.
Show hintHide hint
Consider the balance between area and speed when deciding on hardware implementations.
Question 6.
Evaluate a scenario where performance is critical (e.g., gaming CPUs) versus a situation where cost-efficiency is more essential. Compare how the ALU's design would differ in each case.

Think about the implications for end-users and the intended use of each device.
