Multiple Microprocessor Systems: What, Why, and When

Abstract

For many applications-especially those requiring diversified computations in real time or high reliability without massive redundancy-multiple micons-especially those requiring diversified computations in real time or high reliability without massive redundancy-multiple microprocessor systems are the logical choice. Multiple microprocessor systems can provide an appropriate solution to the demand for additional computing power to meet new requirements and to support complex applications. To clarify the concept and its associated terminology, this article considers the what, why, and when of multiple microprocessor systems. Aspects that apply to all processors, regardless of size, are presented in general terms. However, since the main interest lies with microprocessor-based systems, aspects that depend on processor power and input/output flexibility are related specifically to microprocessors. 38 references.
