Formalized Methodology for Data Reuse Exploration in Hierarchical Memory Mappings

Efficient use of an optimized memory hierarchy to exploit temporal locality in the memory accesses on array signals can have a very large impact on the power consumption in data dominated applications. In the past, this task has been identified as crucial in a complete low-power memory management methodology. But effective formalized techniques to deal with this specific task haven't been addressed yet. In this paper the design freedom available for the basic problem is explored in-depth and the outline of a systematic solution methodology is proposed. The efficiency of the methodology is illustrated on a real-life motion estimation application
