6.1.4. Module Summary

Try these first

1. 1.

   What are the three phases of the instruction cycle?

   Hint

   Use the acronym FDE.

2. 2.

   What is the role of control signals in the control unit?

   Hint

   Think about how a conductor leads an orchestra.

3. 3.

   What are the primary functions of a control unit?

   • Managing hardware signals
   • Performing calculations
   • Storing data

   Hint

   Think about its role in controlling operations.

4. 4.

   True or False: More bus systems always lead to slower execution.

   • True
   • False

   Hint

   Consider the efficiency of traffic flow with more lanes.

5. 5.

   Propose a new architecture that optimizes the bus system while minimizing control signal complexity. Detail your design considerations and expected benefits.

   Hint

   Think about how quickly information can pass through multiple paths.

6. 6.

   Analyze a given instruction set and compose the corresponding micro instructions needed for execution. Detail each step and its associated control signal.

   Hint

   Draw the flow to visualize the instruction breakdown.
