Riassunto analitico
This thesis consists in the implementation of a hierarchical scheduling framework, a paradigm that allows the coexistence of a number of separate applications in the same processor.<br>In this work new approaches to implement kernel mechanisms for hierarchical scheduling are presented, considering also resource sharing among applications.<br>This new kind of methodology allows to support directly at operating system level the component based development, a new software design approach for embedded systems where subsystems are independently developed and successively integrated, in order to compose the complete system.<br>The presented mechanisms have been implemented in VxWorks 6.9, a commercial real-time operating system developed by WindRiver that is widely adopted for safety-critical applications.<br>
