The Analysis And Implementation Of Quantum Operating System

The thesis designs an operating system with an object-oriented approach, providing a platform with high reusability and stability for developing distributed reactive systems under extremely hardware constrained embedded environment.The thesis first studies the requirement for developing distributed reactive systems and the designes of existing operating systems as well. Then it comes up with an innovative operating system-Quantum operating system, which introduces the uses some software engineering solutions well proven as effective, such as the object-oriented design, design patterns, etc into the designing of distributed reactive systems to solve the ever growing complexity of both the application and communication. Solutions based on the quantum operating system model and implement the distributed reactive applications from a higher and more abstract level, making the designing of stable products easier and faster.The compact system architecture, event-driven scheduling mechanism and optimized memory management design of quantum operating system enable a minimized memory overhead. Test results have proven that quantum OS-based solution causes no more or even less overhead in terms of memory and code size than all the traditional solutions, thus requires no extra cost for hardware resources.
