Coarse-grain reconfigurable architectures consist of a large number of processing elements (PEs) connected together in a network. For mapping applications to such coarse-grain architectures, we present an algorithm that takes into account the number and delay of interconnects. This algorithm maps operations to PEs and data transfers to interconnects in the fabric. We explore three different cost functions that largely affect the performance of the scheduler: (a) priority of the operations, (b) affinity of operations to PEs based on past mapping decisions, and (c) connectivity between the PEs. Our results show that a priority-based operation cost function coupled with a connectivity-based PE cost function gives results that are close to the lower bounds for a range of designs.
