Energy efficient memory assignment

In this paper we describe a novel energy efficient procedure for Storage Bandwidth Optimization (SBO) and memory assignment. We show how loop transformations and array reordering scheme based on heuristic algorithms can be used to reduce some of the conflicts. Reduction of conflicts results in a memory architecture with fewer memory modules and fewer memory ports. We next determine the allocation of arrays to the different memory modules based on integer linear programming (ILP) model and heuristics such that the energy consumption is minimum.
