28.1.1. Different Internal CPU Bus Organization

Try these first

1. 1.

   What does a CPU bus do?

   Hint

   Think about how communication happens inside the CPU.

2. 2.

   What is a program counter?

   Hint

   It's crucial for executing instructions sequentially.

3. 3.

   What is one primary advantage of multiple bus architectures?

   • Lower costs
   • Parallel processing
   • Less complexity

   Hint

   Think about how doing multiple tasks at once is beneficial.

4. 4.

   True or False: A program counter requires fewer steps to update its value in a multiple bus system compared to a single bus system.

   • True
   • False

   Hint

   Reflect on how many actions it takes in each architecture.

5. 5.

   Describe how CPU operations would be impacted if a newly designed system only incorporated a single bus architecture, despite the advancements of multi-bus systems in modern computing.

   Hint

   Consider application scenarios in data-heavy processing.

6. 6.

   Evaluate the trade-offs of implementing a multi-bus architecture in terms of system cost, design complexity, and processing efficiency.

   Hint

   Think about both hardware and software implications.
