In this paper, we present a model-driven approach to RTOS-based embedded software development and an automated tool that can produce RTOS-specific code. Our contributions are two fold. First, we defined generic RTOS APIs (application programming interfaces) that can capture most of typical RTOS services but are not bound to any specific RTOS. The generic(More)
Recent embedded real-time software tends to be multithreaded and constrained by stringent timing requirements, thus often leading to serious faults depending on the precise timing of thread executions and event occurrences. A promising approach to debugging such complicated software is to log appropriate events during runtime and replay the same software(More)
In this paper, we propose a novel technique for the ubiquitous multimedia which is self-networking and replaceable structure. As the content in the ubiquitous multimedia should be realistic and continuously updated in the realtime manner, an efficient scheme of a self-networking and replaceable structure is necessary. In the proposed method, the content(More)
