A COST-EFFECTIVE BUS-BASED MULTIPROCESSOR SYSTEM

Abstract: A bus-based system is very attractive due to its simplicity and ease of use. Existing bus structures can support a limited number of processors. As processors are added to such a system, it reaches a saturation point beyond which it cannot be expanded anymore. This paper presents a new bus structure called the G e n e r a l i z e d Bus I n t e r c o n n e c t i o n. In this bus structure all the processors and memory modules are partitioned into a number of processor and memory groups. A processor group i s connected to each memory group by a set of multiple buses. For a fixed number of buses, this new bus structure can support more processors, than the conventional bus s t ruc tu res. 1. INTRODUCIION There is a constant need for faster computers
