While JJ-based circuits can provide high operating frequency and energy-efficiency, this technology faces three critical challenges: lack of area-efficient technology for memory structures, reduced gate fanout compared to CMOS, and new failure modes of Flux-Traps that occur due to the operating environment.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe lack of dense memory technology restricts the use of superconducting technology in the near term to application domains that have high compute intensity but require a negligible amount of memory. This paper investigates the use of superconducting technology to build an accelerator for SHA-256 engines commonly used in Bitcoin mining applications.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThis work shows that redesigning the accelerator to suit the unique constraints of superconducting technology, such as low fanout, can significantly improve energy efficiency. The paper also develops solutions to make the design\u0026nbsp;tolerant of new fault modes and show how this fault-tolerant design can be leveraged to reduce the operating current, thereby increasing the overall energy-efficiency to 46X compared to the CMOS accelerator.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ESwamit Tannu, Poulami Das, and their Ph.D. advisor, Moinuddin Qureshi, won the Best Paper Award at the ACM Computing Frontiers Conference, held in Sardinia, Italy from April 30-May 2, 2019.\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"Swamit Tannu, Poulami Das, and their Ph.D. advisor, Moinuddin Qureshi, won the Best Paper Award at the ACM Computing Frontiers Conference, held in Sardinia, Italy from April 30-May 2, 2019."}],"uid":"27241","created_gmt":"2019-05-10 20:31:43","changed_gmt":"2019-05-13 12:25:56","author":"Jackie Nemeth","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2019-05-10T00:00:00-04:00","iso_date":"2019-05-10T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"621609":{"id":"621609","type":"image","title":"Swamit Tannu and Poulami Das\u00a0(center and right), with graphic of the Josephson Junction Based SHA-256 Accelerators","body":null,"created":"1557750311","gmt_created":"2019-05-13 12:25:11","changed":"1557750311","gmt_changed":"2019-05-13 12:25:11","alt":"photograph of Swamit Tannu and Poulami Das\u00a0(center and right), with graphic of the Josephson Junction Based SHA-256 Accelerators","file":{"fid":"236774","name":"CF_Picture.png","image_path":"\/sites\/default\/files\/images\/CF_Picture.png","image_full_path":"http:\/\/tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/CF_Picture.png","mime":"image\/png","size":2732432,"path_740":"http:\/\/tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/CF_Picture.png?itok=PSa9iUvi"}},"155101":{"id":"155101","type":"image","title":"Moin Qureshi","body":null,"created":"1449178859","gmt_created":"2015-12-03 21:40:59","changed":"1475894789","gmt_changed":"2016-10-08 02:46:29","alt":"Moin Qureshi","file":{"fid":"195264","name":"qureshi.jpg","image_path":"\/sites\/default\/files\/images\/qureshi_0.jpg","image_full_path":"http:\/\/tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/qureshi_0.jpg","mime":"image\/jpeg","size":47044,"path_740":"http:\/\/tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/qureshi_0.jpg?itok=dnOUewsI"}}},"media_ids":["621609","155101"],"related_links":[{"url":"http:\/\/memlab.ece.gatech.edu","title":"Memory Systems Lab"},{"url":"http:\/\/www.ece.gatech.edu","title":"School of Electrical and Computer Engineering"},{"url":"http:\/\/www.gatech.edu","title":"Georgia Tech"},{"url":"http:\/\/www.computingfrontiers.org\/2019\/","title":"ACM Computing Frontiers Conference"}],"groups":[{"id":"1255","name":"School of Electrical and Computer Engineering"}],"categories":[{"id":"134","name":"Student and Faculty"},{"id":"8862","name":"Student Research"},{"id":"135","name":"Research"},{"id":"153","name":"Computer Science\/Information Technology and Security"},{"id":"145","name":"Engineering"},{"id":"149","name":"Nanotechnology and Nanoscience"},{"id":"150","name":"Physics and Physical Sciences"}],"keywords":[{"id":"181278","name":"Swamit Tannu"},{"id":"181279","name":"Poulami Das"},{"id":"171788","name":"Moinuddin Qureshi"},{"id":"181280","name":"ACM Computing Frontiers Conference"},{"id":"181281","name":"Memory Systems Lab"},{"id":"109","name":"Georgia Tech"},{"id":"166855","name":"School of Electrical and Computer Engineering"},{"id":"181282","name":"Superconducting Accelerators"},{"id":"181283","name":"superconducting circuits"},{"id":"181284","name":"Josephson Junction"},{"id":"12244","name":"energy efficiency"},{"id":"181285","name":"high operating frequency"},{"id":"181286","name":"memory structures"},{"id":"4128","name":"CMOS"},{"id":"181287","name":"SHA-256 engines"},{"id":"181288","name":"Bitcoin mining applications"},{"id":"181289","name":"fault-tolerant design"}],"core_research_areas":[{"id":"39431","name":"Data Engineering and Science"},{"id":"39451","name":"Electronics and Nanotechnology"}],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EJackie Nemeth\u003C\/p\u003E\r\n\r\n\u003Cp\u003ESchool of Electrical and Computer Engineering\u003C\/p\u003E\r\n\r\n\u003Cp\u003E404-894-2906\u003C\/p\u003E\r\n","format":"limited_html"}],"email":["jackie.nemeth@ece.gatech.edu"],"slides":[],"orientation":[],"userdata":""}}}
