Power/energy has been an important constraint for development of electronic system.Power/energy is consumed by hardware when software runs on it

for accessing data and executing instructions of software can both make hardware consume power/energy.Compiler can change the behavior of software running on the hardware by optimized scheduling

such that the power/energy consumption of certain program decreases.This paper comprehensively reviews low power/energy compilation technology related researches from two aspects

how to evaluate software power/energy consumption and how to achieve low power/energy by means of compilation technologies.In the end

we analysis the existing problems in current researches on low power/energy compilation Technology

and predicate some new directions on the low power/energy compilation technology.
