Challenge Problems
Push your limits with challenges.
Question 1
If the fetch cycle was executed with incorrect addresses in the program counter, how would this impact program execution?
💡 Hint: Consider the analogy of a map: if your starting point is wrong, where would you end up?
Question 2
Discuss how the performance of the fetch cycle can influence the overall speed of a CPU, especially in relation to memory speed.
💡 Hint: How can you perform multiple tasks at once to save time?
