Inactive-Withdrawn Standard

IEEE/ISO/IEC 10861-1994

ISO/IEC International Standard for Information Technology- Microprocessor Systems- High-Performance Synchronous 32-Bit Bus: Multibus II

The operation, functions, and attributes of a parallel system bus (PSB), called MULTIBUS II, are defined. A high-performance backplane bus intended for use in multiple processor systems, the PSB incorporates synchronous, 32-bit multiplexed address/data, with error detection, and uses a 10 MHz bus clock. This design is intended to provide reliable state-of-the-art operation and to allow the implementation of cost-effective, high-performance VLSI for the bus interface. Memory, I/O, message, and geographic address spaces are defined. Error detection and retry are provided for messages. The message-passing design allows a VLSI implementation, so that virtually all modules on the bus will utilize the bus at its highest performance–32 to 40 Mbyte/s. An overview of PSB, signal descriptions, the PSB protocol, electrical characteristics, and mechanical specifications are covered.

Other Activities From This Working Group

Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.


No Active Projects

Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.


No Active Standards

These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.


No Superseded Standards

These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.


No Inactive-Withdrawn Standards

These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.


No Inactive-Reserved Standards
