AbstractUnder MDA07-005 Harmonia, Inc., in partnership with Raytheon SAS, is building a system named uReuseT to cost effectively modernize legacy information, sensor, space platform, and weapons systems such as the Space Tracking and Surveillance System (STSS) written in legacy languages like Ada. We are developing an innovative new toolset that guides engineers through a comprehensive methodology to inventory and understand a legacy system, estimate the cost/benefit of reusing versus rewriting the legacy code, extract and translate reusable components from the legacy system for use in new architectures, and verify the correctness of the translated code. Our toolset improves upon the state of the art in several ways: breaks the "black box" of most conversion methods to facilitate a human-involved process of discovery; reduces cost by automating tedious migration tasks; fosters and encourages "educated conversion," allowing the engineer to understand the code as it is converted; visualizes code structure to assist understanding, permits annotation of source code, provides user-customizable conversions, measures real-time code lengths; and utilizes Open Source technology including Eclipse to provide a robust platform for migrating legacy code to C or C++ that is extensible to C++ .NET, Java, and other languages within STSS and beyond.
