ABSTRACT
The EARtH algorithm finds the optimal voltage and frequency operational point of the processor in order to achieve minimum energy of the computing platform. The algorithm is based on a theoretical model employing a small number of parameters, which are extracted from real systems using off-line and run-time methods. The model and algorithm have been validated on real systems using 45nm, 32nm and 22nm Intel® Core processors. The algorithm can save up to 44% energy compared with the commonly used fixed frequency policies.
