This paper describes a system-level modeling method in UML for performance evaluation of embedded systems. The core technology of this modeling method is reverse modeling based on dynamic analysis. A case study of real MFPs (multifunction peripherals/printers) is presented in this paper to evaluate the modeling method.
We propose a coarse-grained simulation method which takes the effect of memory access contention into account. The method can be used for the evaluation of the execution time of an application program during the system architecture design in an early phase of development. In this phase, information about memory access timings is usually not available. Our(More)
As the development of embedded systems grows in scale, it is becoming more important for engineers to share development documents such as requirements, design specifications and testing specifications, and to accurately circulate and understand the information necessary for development. Also, many defects that can be originated in the surface expression of(More)
