Reducing Engergy Consumption in Programs Using Cohesion Technique

Abstract

Abstract-The objective of this work is to reduce energy consumption of source programs written in C. The underlying technique employs code transformation which focuses on cohesion. Four classes of transformations will be considered: function, loop optimization, control structure, and operator. Code transformation is evaluated by effectiveness, efficiency, space complexity, number of instructions executed, number of pages, size of memory page allocated, and energy consumption. The results suggest that different cohesion level will affect the energy consumption. Moreover, different types of source code yield different energy consumptions based on cohesion measures.

Towards green power electronics: software controllers and domain knowledge

“…In general, neither of the approaches provides significant reduction in energy consumption. For instance in [11] authors concluded that by applying the static approach using the cohesion technique, and in [13] authors aim at finding patterns that would result in minimal energy consumption that could be used during code generation. Moreover, the dynamic approach is questionable in safety-critical real-time systems, where predictability is the key characteristic of the system.…”
