12.1. Computer Organization and Architecture: A Pedagogical Aspect

Try these first

1. 1.

   What does the program counter do in single bus architecture?

   Hint

   Think about instruction sequence.

2. 2.

   Name the three phases of the instruction cycle.

   Hint

   Recall the flow of executing a program.

3. 3.

   What role does the control unit play in instruction execution?

   Hint

   Consider how signals are formed and their purpose.

4. 4.

   True or False: In single bus architecture, multiple devices can transmit data simultaneously.

   Hint

   Recall the nature of the communication structure.

5. 5.

   How would you contrast the performance implications of single bus architecture against a multiple bus architecture in instruction execution?

   Hint

   Consider how data traffic impacts performance.

6. 6.

   Imagine designing a new instruction set. Describe how you would account for the control signals needed in your architecture for various instruction types.

   Hint

   Think about the variety of operations and their dependent signals.
