“…After the re-adjustment of formal timing specifications, time traces generated at runtime by the translated example and multirotor applications fit into the defined timing contracts. However, the static translation process involves a considerable overhead (analysed through a feasibility study by Yarza et al (2020)) which might not be affordable depending on the application to be ported. For each particular case, an expert should assess, considering the incurred overhead, whether the RT legacy software migration solution is acceptable.…”

“…As a first step on this research, Yarza et al (2020) studies the feasibility of two machine-adaptable binary translators, one dynamic and the other one static, for their use in a RT property conserving legacy software migration process. From this feasibility study, the static approach is selected to implement a timing contract aware real-time legacy software migration solution.…”

The evolution to next generation embedded systems is shortening the obsolescence period of the underlying hardware. As this happens, software designed for those platforms (a.k.a., legacy code), that might be functionally correct and validated code, may be lost in the architecture and peripheral change unless a retargeting approach is applied. Embedded systems often have real-time computing constraints, therefore, the legacy code retargeting issue directly affects real-time systems. When dealing with real-time legacy code migration, the timing as well as the functional behaviour must be preserved. This article sets the focus on the timing issue, providing a migration path to real-time legacy embedded control applications by integrating a portable timing enforcement mechanism into a machine-adaptable binary translation tool. The proposed timing enforcement solution provides at the same time means for validating the legacy timing behaviour on the new hardware platform using formal timing specifications in the form of contracts.
