Abstract

The variety of applications for field programmable gate arrays (FPGAs) is continuously growing, thus it is important to address power consumption issues during the operation. As technological node shrinks, leakage power becomes increasingly critical in overall power consumption of FPGA. The technique of configuration pre-fetching (loads configurations as soon as possible) adopted to achieve high performance is one of the major reasons of leakage waste since regions containing reconfiguration information cannot be powered down in between the time gap of reconfiguration and execution. In this work, we present a heuristic approach to minimize the leakage power consumption for twodimensional reconfigurable FPGA architectures. The heuristic scheduler is based on list scheduling and exploits dynamic priority for sorting the tasks into schedule order and a cost function for cell allocation. Farthest placement scheme is adopted for anti-fragmentation purpose. The cost function provides control to compromise between leakage dissipation and schedule length.
