3 cards from this section. Quick, good the night before a test.
What does MDR stand for?
Think about the role of the register in data transfer.
What signal indicates that reading is complete?
This signal tells us to stop reading.
What does the MFC signal indicate?
Recall the specific role of the MFC signal.
True or False: The values from register R1 can be written to memory directly without using the MDR.
Consider the need for an intermediary during transfers.
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.
Focus on the consequences of poor timing.
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?
Consider how multiple paths affect overall operation.
