28.4. Parallel Operations and Performance

Try these first

1. 1.

   What is the main advantage of using a multiple bus architecture?

   Hint

   Think about how tasks are executed simultaneously.

2. 2.

   Define the purpose of the Program Counter.

   Hint

   Consider its role in instruction execution.

3. 3.

   What is the primary advantage of a multi-bus architecture?

   • Increased cost
   • Slower performance
   • Parallel operations
   • Less tangible benefits

   Hint

   Consider how tasks are executed.

4. 4.

   True or False: A single bus architecture allows for faster execution of operations compared to multi-bus architectures.

   • True
   • False

   Hint

   Think about the execution style.

5. 5.

   Design a simple model of a CPU with both single and multiple bus architectures. Explain the data flow and the expected performance in both scenarios.

   Hint

   Draw diagrams to illustrate the comparison.

6. 6.

   Evaluate how shifting from a single bus to a multi-bus architecture impacts overall system design, focusing on cost, complexity, and performance metrics.

   Hint

   Consider how each aspect changes—what are the trade-offs?
