Abstract : A study was undertaken to examine the issues involved in establishing instruction set architecture (ISA) standards for computers used in embedded spaceborne applications on Air Force Space Division projects. The specific areas addressed were (a) Space Division requirements and ISA tradeoffs, (b) comparisons of military standard and commercial spaceborne ISAs, (c) an LSI implementation study and (d) an LSI cost study. The bottom line of the study is that the MIL-STD-1750A ISA addresses the onboard processing needs of all present and near term Space Division projects as well as many of those on far term projects. In addition, the development of space qualified 1750A computers should be a low risk project with relatively modest costs once the efforts currently sponsored by other agencies are successfully completed.
