Remember the distinction between general purpose and specialized registers.
Question 5.
Explain how the CPU would add two values located in memory, detailing the roles of the MAR, MDR, and general-purpose registers involved.
Show hintHide hint
Consider the data flow from memory to the registers and finally to the ALU.
Question 6.
Discuss the impact of choosing a simple ALU configuration versus a complex one that can handle multiple operations in parallel. What trade-offs might a CPU designer face?
Show hintHide hint
Think of scenarios where speed is crucial versus when cost limitations might be more important.
