Real-time tasks that synchronize to enforce mutually exclusive access to the shared resources could be blocked by lower priority tasks. While dynamic voltage scaling (DVS) is known to reduce dynamic power consumption, it causes increased blocking time due to lower priority tasks that prolong the interval over which a computation is carried out. Additionally, processor slowdown to increase execution time implies greater leakage energy consumption. In this paper, a leakage-controlled method is proposed, which decreases both priority inversion and power consumption. Based on priority ceiling protocol (PCP) and a graph reduction technique, this method can decrease more energy consumption and avoid priority inversion for real-time tasks. <\/jats:p>","DOI":"10.1155\/2014\/428230","type":"journal-article","created":{"date-parts":[[2014,2,13]],"date-time":"2014-02-13T21:03:21Z","timestamp":1392325401000},"page":"428230","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["A Blocking-Aware Scheduling for Real-Time Task Synchronization Using a Leakage-Controlled Method"],"prefix":"10.1177","volume":"10","author":[{"given":"Mu-Yen","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Information Management, National Taichung University of Science and Technology, Taichung City 404, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1185-7208","authenticated-orcid":false,"given":"Da-Ren","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Information Management, National Taichung University of Science and Technology, Taichung City 404, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5520-505X","authenticated-orcid":false,"given":"Shu-Ming","family":"Hsieh","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, Hwa Hsia Institute of Technology, New Taipei City 235, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,2,13]]},"reference":[{"volume-title":"Proceedings of the 15th Annual IEEE International ASIC\/SOC Conference","author":"Duarte D.","key":"B7-2014-428230"},{"first-page":"153","volume-title":"Proceedings of the ACM SIGPLAN\/SIGBED Conference on Languages, Compilers, and Tools for Embedded Systems (LCTES '06)","author":"Chen J.-J.","key":"B6-2014-428230"},{"first-page":"46","volume-title":"Proceedings of the International Symposium on Low Electronics and Design (ISLPED '01)","author":"Gruian F.","key":"B8-2014-428230"},{"first-page":"37","volume-title":"Proceedings of the 14th Annual ACM-SIAM Symposium on Discrete Algorithms","author":"Irani S.","key":"B10-2014-428230"},{"first-page":"57","volume-title":"Proceedings of the ACM SIGPLAN\/SIGBED Conference on Languages, Compilers, and Tools for Embedded Systems (LCTES '04)","author":"Jejurikar R.","key":"B13-2014-428230"},{"first-page":"275","volume-title":"Proceedings of the 41st Design Automation Conference","author":"Jejurikar R.","key":"B16-2014-428230"},{"first-page":"788","volume-title":"Proceedings of the Design Automation and Test in Europe (DATE '02)","author":"Kim W.","key":"B18-2014-428230"},{"first-page":"396","volume-title":"Proceedings of the 2003 International Symposium on Low Power Electronics and Design (ISLPED '03)","author":"Kim W.","key":"B19-2014-428230"},{"first-page":"393","volume-title":"Proceedings of the 2004 International Symposium on Lower Power Electronics and Design (ISLPED '04)","author":"Kim W.","key":"B20-2014-428230"},{"issue":"1","key":"B21-2014-428230","first-page":"93","volume":"1","author":"Liang W.
