Reengineering: An Affordable Approach for Embedded Software Upgrade; Journal article

摘要

Within the Department of Defense, embedded information systems found in aging aircraft are facing readiness, supportability, and upgrade challenges due to diminished manufacturing sources (DMS), which impacts both embedded processing hardware and software development tools. In many cases, however, the embedded software functionality within these systems is still highly viable. Under the Embedded Information System Reengineering project, the Air Force Research Laboratory Information Directorate and Lockheed Martin Aeronautics Company have matured a legacy software reengineering capability that eliminates software tooling DMS, permitting affordable application support and upgrade. A successful flight demonstration aboard a U.S. Air Force F-117 stealth fighter aircraft was recently conducted to verify correct performance of reengineered weapon system software components generated using high degrees of automation assistance.
