Compilation et faible consommation

Although it has been widely studied from a hardware point of view, this domain remains less explored in software, especially with respect to compiler support where historically optimizations generally dealt with speed.

Although it has been widely studied from a hardware point of view, this domain remains less explored in software, especially with respect to compiler support where historically optimizations generally dealt with speed. This paper thus aims at providing a survey of low-power and low-energy compilation techniques. It briefly introduces low-level techniques, then presents more largely higher-level techniques, especially those pertaining to memory management and operation modes of resources, before drawing the domain perspectives
