IEEE 896.1-1987

IEEE 896.1-1987 is a technical standard for backplane bus specifications in multiprocessor architectures, focusing on the Futurebus+(R) environment. It defines a framework for how multiple processing elements can share a common bus structure with predictable electrical and interface behavior. For computing and processing systems, this kind of specification matters because it supports consistent design, interoperability, and controlled implementation of complex hardware assemblies where bus performance and integration are critical.

IEEE 896.1-1987 overview

This standard addresses the backplane bus layer used in multiprocessor architectures, where several processors, memory resources, and related components may need to communicate efficiently over a shared system fabric. As IEEE 896.1-1987, it sits within a specialized hardware design context rather than a general-purpose computing guideline. The document is relevant to engineers working on system architecture, bus interface definition, and component-level compatibility for Futurebus+(R)-based platforms.

Typical use cases

Typical use cases include designing or evaluating multiprocessor backplanes, integrating controller and memory modules, and specifying bus behavior for complex computing equipment. It may also be used when documenting interface requirements for modular hardware systems that depend on shared communication across boards or cards. In practice, IEEE 896.1-1987 can help support architecture planning, prototype validation, and procurement decisions for systems that need a structured bus specification.

Why this standard matters

This standard matters because backplane bus behavior strongly affects how well multiprocessor systems operate as a whole. Clear specifications reduce ambiguity during design and testing, helping teams compare implementations against a common technical reference. Using IEEE 896.1-1987 can also improve consistency across components, lower integration risk, and support more reliable acceptance checks when hardware is assembled from multiple modules or vendors. Its superseded status is still useful for legacy system work and historical reference.
