The battery life is determined by the amount of power consumption and there are design challenges for low power and high performance microprocessors. To achieve our objective, we first distribute a workload uniformly and then apply dynamic voltage and frequency scaling (DVFS) to reduce power consumption dynamically. According to workload of the multi-threaded application, we can adjust the number of core to execute before we run the application. Besides, our approach can reassign workload to alive cores if some cores crash. For this case, if a core breaks down at run time, the power management unit will send a trap to OS, then pthread scheduler will dynamically reassign the workload to alive cores. To evaluate the proposed approach, we perform experiments for our own multicore. The result shows that our approach can work well for various cases.<\/jats:p>","DOI":"10.3233\/978-1-61499-484-8-298","type":"book-chapter","created":{"date-parts":[[2025,2,20]],"date-time":"2025-02-20T12:06:08Z","timestamp":1740053168000},"source":"Crossref","is-referenced-by-count":0,"title":["Dynamic Voltage and Frequency Scaling Optimization for Multicore Architectures"],"prefix":"10.3233","author":[{"family":"Chien Ting-Hsuan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Chang Rong-Guey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Intelligent Systems and Applications"],"original-title":[],"deposited":{"date-parts":[[2025,2,20]],"date-time":"2025-02-20T13:02:42Z","timestamp":1740056562000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0922-6389&volume=274&spage=298"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-484-8-298","relation":{},"ISSN":["0922-6389"],"issn-type":[{"value":"0922-6389","type":"print"}],"subject":[],"published":{"date-parts":[[2015]]}}}
