Migration of DIINS to PowerPC/VxWorks and Intel/Win32

摘要

This report documents the results of work required to migrate the DIINS (Dual Inertial Integrated Navigation System) software from its former platform, consisting of a unix-based Sparc host system and Motorola 68030 VME target system under a Telesoft Ada83 compiler and run-time executive, to a new Green Hills Ada95 NT development environment and two new run-time platforms: a PowerPC604 VME target system running VxWorks 5.4, and a generic personal computer running Windows NT 4.0. The migration is not entirely complete, though both new run-time platforms are running satisfactorily to a great extent. This document records the status of the migration, presents some results of the systems in real-time laboratory trials, and identifies issues that need to be explored more fully if the migrated DIINS systems are to be deployed in operational environments.
