This paper presents an architecture style description language for real-time systems on the basis of existing ADLs ,which is called NewRob.A basic specification in NewRob consists of a synchronous control task that practices the dynamic reconfiguration of the system controller as a set of asynchronous components.The architecture evolves by hierarchical refinement and decomposition of servers into lower level tasks.NewRob is given operational semantics by state charts.Also,the semantic rules allow formal ...
