Abstract: The problems of placing and routing of 2D reconfigurable hardware tasks arc important factors of system resource utilization in reconfigurable computing system Reconfigurable hardware tasks,which are based on heterogeneous reconfigurable devices and task models, were properly classified, and a new algorithm named of DRS I}CW was proposed,which can place and route multiple reconfigurable hardware tasks simultaneously. Experiment results indicate that the algorithm can improve the resource utilization of reconfigurable devices and tasks' routing ratio.

Key words: Reconfigurable computing system, Hardware task, Correlative task, Placement and route
