Visualizing Architecture and Algorithm Interaction in Embedded SystemsAbstract:Embedded systems are increasingly becoming integral parts of almost all technology-oriented applications. The complexity and sophisticated nature of these such systems make it very difficult for engineers to exploit the full potential of the system's underlying resources. More often than not, this results in sub-optimal performance. Tools that allow an engineer to quickly evaluate system behaviour and performance can reduce development costs and time-to-market. Visualization techniques have proven invaluable to the design process in the past as they have greatly simplified tasks faced by engineers. Visual representations of views that depict algorithm and architecture interaction are developed to highlight poor algorithm design, problematic hardware-software interfaces, and other reasons behind poor performance in embedded systems. An objected-oriented framework for visual display of design information has been designed and an implementation of this model is discussed. The framework is then used to develop a prototype that implements architecture-algorithm visualization techniques. The theoretical background and issues relating to effective embedded system design are also discussed.Download a Postscript version of this paper.
