Question 1

What is the role of the Control Unit during operand fetching?

  • Execute arithmetic operations
  • Generate control signals for data accessing
  • Store data in registers

💡 Hint: Think about who is controlling the data paths.

Question 2

True or False: The Memory Address Register (MAR) holds the data fetched from memory.

  • True
  • False

💡 Hint: Remember the functions of MAR versus MDR.

Challenge Problems

Push your limits with challenges.

Question 1

Suppose the instruction requires fetching data from an immediate value and a memory location. Explain how the CU orchestrates these two tasks simultaneously.

💡 Hint: Remember how the CU can manage multiple signals to achieve efficiency.

Question 2

Discuss a potential issue that might arise from incorrect control signals during the operand fetch phase and how it could affect the CPU operation.

💡 Hint: Consider the implications of timing and data integrity.
