Overview of bus-based system-on-chip interconnections

This paper introduces the basic properties, such as structure, transfer properties and arbitration of bus-based interconnections for System-on-Chip (SoC) designs. The overview shows that contemporary SoC buses differ only in minor details. As a result, practically every studied interconnection method could rather easily conform to a common interface. Such an interface would enhance design re-use and make system design easier. However, due to their similarity, the choice between buses is not a straightforward task.
