“…For the first level, specific methods and techniques have been proposed for reducing energy consumption at the compiler layer, the operational layer, and the application layer [50,76,90,96,98,100]. These techniques include: powering off parts of the chips, slowing down CPU clock speeds, improving the performance per watt, developing the ability to run in higher-temperature environments, increasing the efficiency of workload management, and powering off parts of the components when they are idle [50,83,85,90].…”
