Abstract
In highly dynamic scenarios a real-time communication/real-time operating system (RCOS/RTOS), which can fulfill all upcoming demands of the application, is normally very extensive. These RCOS/RTOS systems are heavy-weighted and produce much overhead. System resources for an application or a system service are often reserved for worst-case scenarios and are not usable for other applications. We present a self-optimizing RCOS/RTOS with an integrated flexible resource management. Our RCOS/RTOS adapts its services to the application demands and redistributes temporarily unused resources to other applications under hard real-time conditions. The benefit of our system is shown by means of a self-optimizing communication service. The main building block of this communication service is a reconfigurable dual-port Ethernet switch. Using dynamically reconfigurable hardware to implement the switch enables an adaption of the switch to changing requirements during run-time.
