Abstract: In order to speed up reconfiguration and improve automation degree of the reconfigurable digital system, a control structure based on VME bus and a self-organization model were set up for the reconfigurable modules, and a task management strategy based on instruction sequences was proposed. The mathematical reconfiguration model of reconfiguration modules aiming to minimize the consumption of modules with most effective resources utilization was constructed under the condition of constraints. New tasks were decomposed into correlative subtasks based on instruction sequences, and the particle swarm optimization algorithm was used to assign resources of reconfigurable units so that scheduling of reconfiguration resources was realized. A simulation testing was finally provided to validate the effectiveness of the method.

Key words: reconfigurable digital system, resources scheduling, particle swarm optimization, control structure, instruction sequences
