In: Proceedings of the 19th International Parallel and Distributed Processing Symposium (IPDPS 2005) - Reconfigurable Architectures Workshop (RAW), IEEE Computer Society, on CD. 2005.Dynamic reconfiguration is a promising approach for resource efficient utilization of microelectronic systems. However, work on general approaches to model reconfigurable hardware is quite rare. Therefore, we have developed a new analytical model, which can be used for the analysis of the various approaches to dynamic reconfiguration. Based on our model we define metrics for partial reconfiguration to evaluate different system approaches. Our main objective is to analyze placement algorithms for partially reconfigurable architectures. The model is able to consider miscellaneous constraints and cost parameters for online placement. Thus, placement can be adapted to dynamically changing system environments
