This approach addresses the inherent trade-off between precise computation and computational efficiency. This study introduces a novel energy-efficient multiplier specifically designed for image-processing tasks. Integral to the multiplication process are compressors, which play a crucial role in reducing partial products. Moreover, higher-order approximate compressors, including 7:2 and 8:2 configurations, have been meticulously designed and simulated using Verilog coding within the VIVADO environment. The proposed approximated 7:2, and 8:2 compressors utilize 44%, and 41.37% less area, respectively, 52.35%, and 56.61% low-power consumption, respectively, and 13.73%, and 16.77% high speed, respectively, in comparison to exact compressors comparative analysis reveals that these proposed higher-order compressors offer reduced area requirements and lower power consumption compared to existing state-of-the-art techniques. Incorporating these high-performance compressors at the reduction stage of multipliers yields an energy-efficient circuit tailored for error-tolerant applications. The research employs three distinct designs (Design 1, Design 2 and Design 3), each leveraging the proposed higher-order compressors and approximate adders across varying bit-widths (8-, 16-, 32- and 64-bit). Each design presents unique advantages and limitations, catering to the specific requirements of the application. <\/jats:p>","DOI":"10.1142\/s0218126625502615","type":"journal-article","created":{"date-parts":[[2025,3,1]],"date-time":"2025-03-01T04:48:51Z","timestamp":1740804531000},"source":"Crossref","is-referenced-by-count":0,"title":["Efficient Approximate Computing Circuits for Error-Tolerant Applications: Design and Validation of Multipliers with Novel Speculative Adders and Approximate Compressors"],"prefix":"10.1142","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4240-2177","authenticated-orcid":false,"given":"Garima","family":"Thakur","sequence":"first","affiliation":[{"name":"Department of ECE, Chandigarh University, Gharuan, Punjab, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7538-0584","authenticated-orcid":false,"given":"Shruti","family":"Jain","sequence":"additional","affiliation":[{"name":"Department of ECE, Jaypee University of Information Technology, Solan, Himachal Pradesh, India"}]}],"member":"219","published-online":{"date-parts":[[2025,5,15]]},"reference":[{"key":"S0218126625502615BIB001","first-page":"333","volume":"6","author":"Jain N.","year":"2011","journal-title":"J.
