--- res: bibo_abstract: - Existing approaches and tools for the generation of approximate circuits often lack generality and are restricted to certain circuit types, approximation techniques, and quality assurance methods. Moreover, only few tools are publicly available. This hinders the development and evaluation of new techniques for approximating circuits and their comparison to previous approaches. In this paper, we first analyze and classify related approaches and then present CIRCA, our flexible framework for search-based approximate circuit generation. CIRCA is developed with a focus on modularity and extensibility. We present the architecture of CIRCA with its clear separation into stages and functional blocks, report on the current prototype, and show initial experiments.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Linus Matthias foaf_name: Witschen, Linus Matthias foaf_surname: Witschen foaf_workInfoHomepage: http://www.librecat.org/personId=49051 - foaf_Person: foaf_givenName: Tobias foaf_name: Wiersema, Tobias foaf_surname: Wiersema foaf_workInfoHomepage: http://www.librecat.org/personId=3118 - foaf_Person: foaf_givenName: Hassan foaf_name: Ghasemzadeh Mohammadi, Hassan foaf_surname: Ghasemzadeh Mohammadi foaf_workInfoHomepage: http://www.librecat.org/personId=61186 - foaf_Person: foaf_givenName: Muhammad foaf_name: Awais, Muhammad foaf_surname: Awais foaf_workInfoHomepage: http://www.librecat.org/personId=64665 orcid: https://orcid.org/0000-0003-4148-2969 - foaf_Person: foaf_givenName: Marco foaf_name: Platzner, Marco foaf_surname: Platzner foaf_workInfoHomepage: http://www.librecat.org/personId=398 bibo_doi: 10.1016/j.microrel.2019.04.003 bibo_volume: 99 dct_date: 2019^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/0026-2714 dct_language: eng dct_publisher: Elsevier@ dct_subject: - Approximate Computing - Framework - Pareto Front - Accuracy dct_title: 'CIRCA: Towards a Modular and Extensible Framework for Approximate Circuit Generation@' ...
