Tiivistelmä
This study discusses code maintainability and porting practices and defines the effect they have on each other. Theoretical sources were used to study the topic from an industry point of view, and a code porting project was carried out for a company called Convergens Oy with consideration of existing practices to reinforce the defined relations.
The case project allowed the review of the utilisation of maintainability practices, which benefits and downsides they bring, and how their application affects the working and code porting process. The theoretical study covered such maintainability practices as code modularity, APIs and HALs, automated SW testing, single-responsibility principle, code refactoring and SW/HW integration. All the studied practices were evaluated against their potential or practical application in the case project in light of the SW structure and code analysis.
In conclusion, this study defines the effect that following the studied guidelines has on the code porting process, which focuses on legacy code reuse for a new system design. Furthermore, the study discusses how following or excluding certain maintainability guidelines in practice affected the case project. Their downsides and benefits are also presented in the context of the development of a device aimed for mass-production.
