Challenge Problems

Push your limits with challenges.

Question 1

Imagine a scenario where the PC and MAR operate simultaneously to fetch data. What potential resource conflicts can occur, and how would you resolve them?

💡 Hint: Think about the sequence of operations and the importance of timing their execution.

Question 2

Given a hypothetical CPU with a slower memory speed, evaluate how this would affect the overall efficiency of the fetch and execution cycles.

💡 Hint: Consider how effectively the CPU can manage its tasks while awaiting memory operations.
