The IoT device including the proposed sensor processor performs the event-driven sensor data processing based on an accuracy-energy configurable event-quantization in architectural level. The received sensor signal is converted into a sequence of atomic events, which is extracted by the signal-to-atomic-event generator (AEG). Using an event signal processing unit (EPU) as an accelerator, the extracted atomic events are analyzed to build the final event. Instead of the sampled raw data transmission via internet, the proposed method delays the communication with a host system until a semantic pattern of the signal is identified as a final event. The proposed processor is implemented on a single chip, which is tightly coupled in bus connection level with a microcontroller using a 0.18\u2009<jats:italic>\u03bc<\/jats:italic>m CMOS embedded-flash process. For experimental results, we evaluated the proposed sensor processor by using an IR- (infrared radio-) based signal reflection and sensor signal acquisition system. We successfully demonstrated that the expected power consumption is in the range of 20% to 50% compared to the result of the basement in case of allowing 10% accuracy error.<\/jats:p>","DOI":"10.1155\/2014\/546563","type":"journal-article","created":{"date-parts":[[2014,12,14]],"date-time":"2014-12-14T16:01:16Z","timestamp":1418572876000},"page":"1-16","source":"Crossref","is-referenced-by-count":2,"title":["Accuracy-Energy Configurable Sensor Processor and IoT Device for Long-Term Activity Monitoring in Rare-Event Sensing Applications"],"prefix":"10.1155","volume":"2014","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5560-873X","authenticated-orcid":true,"given":"Daejin","family":"Park","sequence":"first","affiliation":[{"name":"School of Electronics Engineering, Kyungpook National University, Daegu 702-701, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9330-6118","authenticated-orcid":true,"given":"Jeonghun","family":"Cho","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, Kyungpook National University, Daegu 702-701, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/tsmcc.2012.2198883"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/tcad.2004.839485"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/TCAD.2012.2217962"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1145\/1080695.1069988"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/surv.2012.110112.00192"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/jetcas.2013.2243032"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/MPRV.2002.1037719"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/tvlsi.2010.2102055"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1109\/tsp.2007.894417"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1109\/tcsvt.2012.2203739"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1109\/tmc.2012.52"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1109\/tcsii.2010.2056012"}],"container-title":["The Scientific World Journal"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/tswj\/2014\/546563.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/tswj\/2014\/546563.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/tswj\/2014\/546563.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,7,28]],"date-time":"2016-07-28T22:04:00Z","timestamp":1469743440000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/tswj\/2014\/546563\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":12,"alternative-id":["546563","546563"],"URL":"https:\/\/doi.org\/10.1155\/2014\/546563","relation":{},"ISSN":["2356-6140","1537-744X"],"issn-type":[{"type":"print","value":"2356-6140"},{"type":"electronic","value":"1537-744X"}],"subject":[],"published":{"date-parts":[[2014]]}}}
