Analysis and design of the real-time database Polyhedra in the DySCAS architecture platform The purpose of this Master’s project was to analyze how the so called real-time database Polyhedra could be used in the DySCAS platform. This was accomplished by a theoretical study which included DySCAS documentation, Polyhedra manuals, real-time database research rapports and literature. The outcome of this analyze showed that Polyhedra can not be viewed as a real-time database because it does not have some of the necessary features such as handling priorities. This fact has to be considered in the future if Polyhedra should be used in the DySCAS platform. Polyhedra should not be used in safety-critical systems. The DySCAS platform also includes an infotainment layer which mostly handles multimedia and does not have hard real-time demands. It should not arise any negative real-time effects using Polyhedra in the infotainment layer, if it does not affect the other layers which have higher demands when it comes to real-time and deterministic requirements. There was also done a design and implementation of a Polyhedra scenario in the DySCAS prototype platform. Sammanfattnin
