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.
