Source code refactorings and transformations are extensively used by embedded system developers to improve the quality of applications, often supported by various open source and proprietary tools. They either aim at improving the design time quality, such
as the maintainability and reusability of software artifacts, or the runtime quality such as performance and energy eiciency. How-
ever, an inherent trade-of between design- and run-time qualities is often present posing challenges to embedded software development. This work is a irst step towards the investigation of the impact of transformations for improving the performance and the energy efficiency on software quality metrics and the impact of refactorings for increasing the design time quality on the execution time, the memory and the energy consumption. Based on a set of embedded applications from widely used benchmark suites and
typical transformations and refactorings, we identify interrelations and trade-offs between the aforementioned metrics.
