Run-Time Management of Dynamically Recon gurable Designs

A method for managing recon gurable designs, which supports run-time con guration transformation, is proposed. This method involves structuring the recon guration manager into three components: a monitor, a loader, and a con guration store. Di erent trade-o s can be achieved in con guration time, optimality of the con gured circuits, and the complexity of the recon guration manager, depending on the reconguration methods and the amount of run-time information available at compile time. The proposed techniques, implementable in hardware or software, are supported by our tools and can be applied to both partially and non-partially recon gurable devices. We describe the combined and the partitioned recon guration methods, and use them to illustrate the techniques and the associated trade-o s.
