A COTS-based solution for reliable upgrade of legacy systems

The INSERT research project, the F-16 Automated Maneuvering and Attack System algorithm, was re-engineered from JOVIAL into a Unified Modeling Language (UML) design using the Rhapsody Tool from Ilogix, Inc. C++ code was autogenerated and the resulting executable was hosted on an Intel based PC running the LynxOS Real-Time Operating System (RTOS). Simulator testing confirmed that the re-engineered code performed exactly as the original specification required. This experiment indicates that cost savings of 80% could be achieved over original development costs. DARPA, the Air Force Research Laboratory Information Directorate, Lockheed Martin Aeronautics Company, Fort Worth, TX, and Carnegie Mellon University are researching a COTS based approach to developing reliable software upgrade approaches under the Incremental Software Evolution for Real Time Systems (INSERT) project
