Migrating legacy control software to multi-core hardware

Abstract

This paper reports on a case study on analyzing, structuring and re-using real-time control algorithms which represent a significant amount of intellectual property. As a starting point, legacy code written in ADA together with a Windows-based testing framework is available. The goal is to migrate the code onto a real-time multi-core platform taking advantage of technological progress.We present a tool-supported three-step approach for such legacy control software: identifying and isolating the control algorithms, preparing these algorithms and their information exchange for execution within a modern execution framework for Linux written in C ++ , and validating the solution by a) performing regression testing to ensure partial correctness and b) validating its real-time properties.
