COMMUNICATION PERFORMANCE IN A HIERARCHICAL BUS SYSTEM

. Abstrac t: This paper presents the analysis of a new bus structure, called the hierarchical bus structure. The exact analytical model of a 2-level hierarchical bus is developed in this paper. The results from both the analytical model and simulation are shown in the paper. These results show that a hierarchical bus would be a cost effective bus structure as compared to the conventional multiple bus and partial multiple bus s t r u c t u r e s. I. INTRODUCMON A single bus multiprocessor system is the most simple and inexpensive system among all the bus-based systems. However, the single bus provides very limited bandwidth. Thus, only few processor
