On Resource Allocation in Architectural Models

Resource allocation decisions are critical for the design of embedded real-time systems. Today's trend to software integration makes these decisions tightly coupled to the software architecture. In this paper we discuss the use of architectural models to guide and maintain the integrity of the resource allocation decision at different levels of refinement of the system design. We discuss the budgeting process to split the development process into different teams, the use of bin packing techniques for low level resource allocation and the isolation strategies to separate the different criticality levels of these systems.
