Abstract
This paper presents a metrics-driven process and software toolset for the engineering of concurrent, object-oriented, real-time systems. In the engineering of real-time systems, the objective need not be to exploit all potential concurrency, but to exploit only as much concurrency as is needed to enable satisfaction of timing constraints. Thus, the systems engineering process presented in the paper utilizes inter-object concurrency selectively, as a means to meet timelines. To support the selective use of concurrency, this paper describes techniques for computing inter-object concurrency metrics. It is also shown how the concurrency metrics are used to guide the mapping of objects onto processors.
