Software architecture in realtime systems

Software architecture is receiving attention as engineers search for high leverage representations and tools for system design and analysis. The author's approach to software architecture addresses both system structure and communication behavior from four different views: conceptual, module, code and execution. A system is described within a view using domain-specific components and connectors. Correspondences between the views may be used for consistency checking and other forms of analysis. The paper illustrates the use of correspondences in the analysis of realtime performance through an example from the medical patient monitoring domain.<
