Abstract

Dynamic reconfiguration for fine grained architectures is still associated with significant reconfiguration costs. In this paper we propose a new reconfiguration aware design flow. The tools in this flow implement a set of tasks concurrently. The flow leads to task implementations with minimal costs for routing reconfiguration. This is mainly achieved by our mapping tool which solves two fundamental problems: Our mapping algorithm generates variants for the mapping of netlist cells to logic blocks. From those logic blocks a subset for each task is selected that minimizes the cost for routing reconfiguration. We derive a cost function and formulate an integer linear program to solve this problem. We implemented several task sets with our method and compare the results to previous solutions. We show that the reconfiguration aware mapping leads to better results than early approaches with vendor provided tools.
