Scalable And Efficient Middleware For Real Time Embedded Systems

The task to design and implement a middleware for embedded real-time systems has, near the normal challenges for building a usual middleware, two additional difficult demands: 1) it must maintain the real-time features of the underlying environment and, 2) it must adapt in the same time to powerful systems and, moreover, fit on small systems (embedded systems). This thesis presents the research done in providing a solution for these problems - OSA+ middleware. The proposed solution is using a well known concept from operating systems - the microkernel architecture. Adapting this concept to a middleware brings a serie of advantages and disadvatages which are analyzed in this thesis.
