An off-line stage computes the minimum frequency required to run the periodic tasks at maximum CPU utilization, the proportion of each task''s job to be run on each CPU, the maximum clock frequency that keeps temperature under a limit, and the available cycles (slack) with respect to the system with minimum frequency. Then, a Zero-Laxity online scheduler dispatches the periodic tasks according to the offline calculation. Upon the arrival of aperiodic tasks, it increases clock frequency in such a way that all periodic and aperiodic tasks are properly executed. Thermal and temporal requirements are always guaranteed, and energy consumption is minimized. 000079731 536__ $$9info:eu-repo/grantAgreement/ES/DGA/T48$$9info:eu-repo/grantAgreement/EC/H2020/687698/EU/High Performance and Embedded Architecture and Compilation/HiPEAC$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 687698-HiPEAC$$9info:eu-repo/grantAgreement/ES/MINECO/TIN2016-76635-C2-1-R 000079731 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000079731 592__ $$a0.298$$b2018 000079731 593__ $$aControl and Systems Engineering$$c2018$$dQ3 000079731 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000079731 700__ $$aDesirena-López, G. 000079731 700__ $$aRamírez-Treviño, A. 000079731 700__ $$0(orcid)0000-0001-5940-9837$$aBriz, J.L.$$uUniversidad de Zaragoza 000079731 7102_ $$15007$$2035$$aUniversidad de Zaragoza$$bDpto.
