A new fast algorithm is identified using numerical search methods for approximating DST-VII without employing multipliers. In addition, recently proposed fast algorithms for approximating the 8-point DCT-II are now extended to approximate DST-II. All proposed approximations for DST-II and DST-VII are compared with ideal transforms, and circuit complexity is measured using FPGA-based rapid prototypes on a 90[Formula: see text]nm Xilinx Virtex-4 device. The proposed architectures find applications in emerging video processing standards such as H.265\/HEVC. <\/jats:p>","DOI":"10.1142\/s0218126617500451","type":"journal-article","created":{"date-parts":[[2016,10,20]],"date-time":"2016-10-20T08:47:14Z","timestamp":1476953234000},"page":"1750045","source":"Crossref","is-referenced-by-count":4,"title":["Fast Algorithms and Architectures for 8-Point DST-II\/DST-VII Approximations"],"prefix":"10.1142","volume":"26","author":[{"given":"Renato J.","family":"Cintra","sequence":"first","affiliation":[{"name":"Signal Processing Group, Department of Statistics, Universidade Federal de Pernambuco, Recife, PE, Brazil"},{"name":"LIRIS, Institut National des Sciences Appliqu\u00e9es, Lyon, France"},{"name":"\u00c9quipe Cairn, INRIA-IRISA, Universit\u00e9 de Rennes 1, Rennes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F\u00e1bio M.","family":"Bayer","sequence":"additional","affiliation":[{"name":"Department of Statistics and LACESM, Universidade Federal de Santa Maria, Santa Maria, RS, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arjuna","family":"Madanayake","sequence":"additional","affiliation":[{"name":"ECE, The University of Akron, Akron, Ohio, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Uma S.","family":"Potluri","sequence":"additional","affiliation":[{"name":"ECE, The University of Akron, Akron, Ohio, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amila","family":"Edirisuriya","sequence":"additional","affiliation":[{"name":"ECE, The University of Akron, Akron, Ohio, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2016,11,21]]},"reference":[{"key":"S0218126617500451BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/TCSII.2011.2158265"},{"key":"S0218126617500451BIB002","doi-asserted-by":"publisher","DOI":"10.1109\/TVLSI.2009.2037968"},{"key":"S0218126617500451BIB003","doi-asserted-by":"publisher","DOI":"10.1016\/B978-012373624-6\/50003-5"},{"key":"S0218126617500451BIB004","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4615-6199-6"},{"key":"S0218126617500451BIB005","doi-asserted-by":"publisher","DOI":"10.1109\/30.125072"},{"key":"S0218126617500451BIB006","doi-asserted-by":"publisher","DOI":"10.1155\/2007\/57291"},{"key":"S0218126617500451BIB010","doi-asserted-by":"publisher","DOI":"10.1109\/TCSVT.2003.815165"},{"key":"S0218126617500451BIB012","doi-asserted-by":"publisher","DOI":"10.1049\/el:20082239"},{"key":"S0218126617500451BIB014","doi-asserted-by":"publisher","DOI":"10.1109\/LSP.2011.2163394"},{"key":"S0218126617500451BIB015","doi-asserted-by":"publisher","DOI":"10.1049\/el.2012.1148"},{"key":"S0218126617500451BIB016","doi-asserted-by":"publisher","DOI":"10.1088\/0957-0233\/23\/11\/114003"},{"key":"S0218126617500451BIB018","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2013.12.027"},{"key":"S0218126617500451BIB019","doi-asserted-by":"publisher","DOI":"10.1016\/j.ipl.2013.06.008"},{"key":"S0218126617500451BIB024","doi-asserted-by":"publisher","DOI":"10.1049\/el:19951254"},{"key":"S0218126617500451BIB025","unstructured":"H.
