30. Examples of Multiple Bus Architecture
This chapter delves into the advantages and disadvantages of a multiple bus architecture in computer systems, particularly focusing on instruction fetching and data processing. It presents two contrasting cases that illustrate how multiplicity in bus architecture can sometimes simplify the processing stages by reducing the need for temporary registers. Despite these advantages, there are specific scenarios where having additional buses may not significantly decrease operational timelines compared to single bus architecture.

What we have learnt
- Multiple bus architectures are generally advantageous as they allow parallel processing.
- In certain cases, such as specific instruction executions, the benefits of multiple buses may not significantly improve performance.
- Significant reduction in the need for temporary registers can streamline the overall control signals and steps in data processing.
Key Concepts
- -- Multiple Bus Architecture
- An architectural design in computing that employs several data paths for better parallelism in instruction processing.
- -- Temporary Register
- A register used for holding data temporarily during the execution of commands to facilitate intermediate steps.
