31.1.2. Three Bus Architecture Complexity

Try these first

1. 1.

   What is the function of the Memory Data Register (MDR)?

   Hint

   What role does the MDR play in data transfer?

2. 2.

   How many buses are in a three-bus architecture?

   Hint

   Count the buses in the architecture.

3. 3.

   What is the role of the Memory Data Register (MDR)?

   • Holds data being transferred
   • Controls bus operations
   • Executes arithmetic operations

   Hint

   Think about what happens when data is read from memory.

4. 4.

   True or False: A three-bus architecture allows multiple operations to be executed simultaneously.

   • True
   • False

   Hint

   Consider the advantages of having more than one bus.

5. 5.

   Design a flowchart to illustrate the data transfer from the MDR to a register using a three-bus architecture. Explain your flowchart.

   Hint

   Focus on depicting each stage of the data transfer clearly.

6. 6.

   Create a table comparing the control signals needed for a single-bus architecture versus a three-bus architecture when performing the same instruction. Analyze the efficiency.

   Hint

   Consider how additional pathways impact signal requirements.
