Overview: Power consumption of multimedia applications executing on embedded cores is heavily dependent on data transfers between system memory and processing units. The purpose of this paper is to extend an existing power optimizing methodology based on data-reuse decisions, in order to determine the optimal solution in a rapid and reliable way. An analytical approach is proposed by extracting expressions for the number of accesses to each memory layer. Moreover, the design space is further reduced since these analytical expressions are calculated only for a subset of all transformations.
