11.4.2. Future Topics Overview

Try these first

1. 1.

   What does MDR stand for?

   Hint

   Think about the role of the register in data transfer.

2. 2.

   What signal indicates that reading is complete?

   Hint

   This signal tells us to stop reading.

3. 3.

   What does the MFC signal indicate?

   • Data is being read
   • Reading is complete
   • Writing is in progress

   Hint

   Recall the specific role of the MFC signal.

4. 4.

   True or False: The values from register R1 can be written to memory directly without using the MDR.

   • True
   • False

   Hint

   Consider the need for an intermediary during transfers.

5. 5.

   Given a scenario where delays in control signals lead to simultaneous writing from the MDR and R1 to the bus, describe what outcomes might occur.

   Hint

   Focus on the consequences of poor timing.

6. 6.

   Design a hypothetical CPU that uses multiple data registers. How does this change the operation of write and read from memory compared to standard architecture?

   Hint

   Consider how multiple paths affect overall operation.
