Withdrawn Standard. Withdrawn Date: Jan 10, 2002. No longer endorsed by the IEEE. Futurebus+ standards provide systems developers with a set of tools with which high performance bus-based systems may be developed. This architecture provides a wide range of performance scalability over both cost and time for multiple generations of single- and multiple-bus multiprocessor systems. This document, a companion standard to IEEE Std 896.1-1991, builds on the logical layer by adding requirements for three military profiles. It is to these profiles that products will claim conformance.Othere specifications that may be required in conjunction with this standard are IEEE Std 896.1-1991, IEEE Std 896.2- 1991, IEEE Std 896.3-1993, IEEE Std 896.4-1993, IEEE Std 1101.3-1993, IEEE Std 1101.4-1993, IEEE Std 1212-1991, IEEE Std 1194-1, 1991, IEEE P1394, IEEE Std 1301-1991, and IEEE Std 1301.1-1991.
