The multipliers are power\u2010hungry, and their approximation has been the target of research, especially by using approximate counters. In this study, a low\u2010power and high\u2010speed approximate 4\u2009:\u20092 counter is proposed to add partial product (PP) bits. Also, a new partial product generation (PPG) is introduced by inserting errors in Karnaugh\u2019s map to reduce the circuit complexity. The counter and PPG make a new radix\u20104\u2010based 8\u2009\u00d7\u20098 Booth multiplier, which is synthesized targeting a 32\u2010nm carbon nanotube field\u2010effect transistor (CNTFET) technology to determine the hardware characteristics. Looking at the normalized mean error distance (NMED), the multiplier has a 51.33% power\u2013delay product (PDP) saving and acceptable accuracy. Besides, the multiplier which is configured by the counter and PPG accomplishes a 28.31% savings in the PDP\u2009\u00d7\u2009NMED in comparison with other approximate Booth multipliers. The case study of joint photographic experts group (JPEG) compression is performed, and the proposed multiplier outperforms references by higher quality results along with lower power consumption.<\/jats:p>","DOI":"10.1049\/2024\/3314001","type":"journal-article","created":{"date-parts":[[2024,10,17]],"date-time":"2024-10-17T08:50:02Z","timestamp":1729155002000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["An Efficient Approximate Multiplier with Encoded Partial Products and Inexact Counter for Joint Photographic Experts Group Compression"],"prefix":"10.1049","volume":"2024","author":[{"given":"Elham","family":"Esmaeili","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4683-1814","authenticated-orcid":false,"given":"Nabiollah","family":"Shiri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"265","published-online":{"date-parts":[[2024,10,17]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/TC.12"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TC.2023.3343093"},{"key":"e_1_2_9_3_2","article-title":"A survey on approximate multiplier designs for energy efficiency: from algorithms to circuits","volume":"29","author":"Wu Y.","year":"2023","journal-title":"ACM Transactions on Design Automation of Electronic Systems"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00034-024-02630-4"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/TNANO.2022.3145362"},{"key":"e_1_2_9_6_2","doi-asserted-by":"crossref","unstructured":"LinC.-H.andLinC.
