28.2. Introduction to Multiple Bus Architecture

Try these first

1. 1.

   What is a bus in CPU architecture?

   Hint

   Think about how components talk to each other.

2. 2.

   Name one advantage of a multiple bus architecture.

   Hint

   Consider how many operations can happen at once.

3. 3.

   What is a key advantage of a multiple bus architecture?

   • Increased cost
   • Simultaneous data transfers
   • More temporary registers

   Hint

   Think about how buses help in transferring data.

4. 4.

   True or False: A single bus architecture requires more control signals than a multiple bus architecture.

   • True
   • False

   Hint

   Reflect on how many paths each architecture has.

5. 5.

   Design a theoretical CPU that implements a four-bus architecture. Explain how each bus will function differently and the potential advantages gained.

   Hint

   Consider how separating tasks reduces wait times.

6. 6.

   Evaluate how the implementation of multiple bus architectures can impact the overall CPU performance in real-time systems compared to single bus architectures.

   Hint

   Think about how time sensitivity matters in processing.
