Object Orientation Problems When Applied to the Embedded Systems Domain

Nowadays, with the growing complexity of embedded systems, it is necessary to use techniques and methodologies that in the same time increase the software productivity, while being still able to manipulate physical embedded systems constraints like memory footprint, real-time behavior, power dissipation and so on. Objectoriented modeling and design is a widely-know methodology in software engineering. This paradigm may satisfy the software portability and maintainability requirements, but it presents an overhead in terms of memory, performance and code size. This paper proposes a pragmatic approach, consisting in the use design space exploration tool (DESEJOS Tool) to allow an automatic selection of the best object organization. This tool tries to transform, in an automatic way, as many dynamic objects to static ones, in the goal to reduce execution time, while maintaining memory costs as low as possible. Experimental results are presented and demonstrate that a one can increase by 24% the performance of an MP3 player while paying just 0.3% increase in memory size.
