If such errors affect essential parts of the application, the execution may fail, decreasing outputs quality and energy savings. We present AxRAM, a memory architecture interface for approximate data that allows applications to benefit from energy savings provided by approximate memories, while improving quality of results and failure rates. AxRAM places critical application data into non-approximate memory regions and implements a resilient addressing scheme that reduces invalid data accesses that lead to application crashes. On a voltage-overscaled SRAM, AxRAM reduces 50.97% of application crashes on average when compared to an unprotected approximate memory. Compared to a system using non-approximate SRAM, our proposal reduces energy consumption by 45.36% on average while providing at least 80% output quality.engBrazilian Symposium on Computing System Engineeringhttps://ieeexplore.ieee.org/document/9046069CNPQ::CIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAOEnergia - ConsumoGerenciamento de memória (Computação)ComputaçãoEnergy consumptionMemory Management (Computer science)Computer scienceA resilient interface for approximate data accessinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/conferenceObjectCampo MouraoBrasil9Fabrício Filho, JoãoFelzmann, Isaías BittencourtAzevedo, Rodolfo Jardim deWanner, Lucas Franciscoinfo:eu-repo/semantics/embargoedAccessreponame:Repositório Institucional da UTFPR (da Universidade Tecnológica Federal do Paraná (RIUT))instname:Universidade Tecnológica Federal do Paraná (UTFPR)instacron:UTFPRORIGINALinterfaceapproximatedataaccess.pdfinterfaceapproximatedataaccess.pdfapplication/pdf987273http://repositorio.utfpr.edu.br:8080/jspui/bitstream/1/23892/1/interfaceapproximatedataaccess.pdfe6a17325c710b3d1d707a1d7c9259591MD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81290http://repositorio.utfpr.edu.br:8080/jspui/bitstream/1/23892/2/license.txtb9d82215ab23456fa2d8b49c5df1b95bMD52TEXTinterfaceapproximatedataaccess.pdf.txtinterfaceapproximatedataaccess.pdf.txtExtracted texttext/plain44971http://repositorio.utfpr.edu.br:8080/jspui/bitstream/1/23892/3/interfaceapproximatedataaccess.pdf.txt8e033f268df52681ad1cfd3a91ff30f2MD53THUMBNAILinterfaceapproximatedataaccess.pdf.jpginterfaceapproximatedataaccess.pdf.jpgGenerated Thumbnailimage/jpeg1803http://repositorio.utfpr.edu.br:8080/jspui/bitstream/1/23892/4/interfaceapproximatedataaccess.pdf.jpgd50dacd6c9fc19b7d0adf905e52647c0MD541/238922021-01-19 04:10:07.385oai:repositorio.utfpr.edu.br:1/23892TmEgcXVhbGlkYWRlIGRlIHRpdHVsYXIgZG9zIGRpcmVpdG9zIGRlIGF1dG9yIGRhIHB1YmxpY2HDp8OjbywgYXV0b3Jpem8gYSBVVEZQUiBhIHZlaWN1bGFyLCAKYXRyYXbDqXMgZG8gUG9ydGFsIGRlIEluZm9ybWHDp8OjbyBlbSBBY2Vzc28gQWJlcnRvIChQSUFBKSBlIGRvcyBDYXTDoWxvZ29zIGRhcyBCaWJsaW90ZWNhcyAKZGVzdGEgSW5zdGl0dWnDp8Ojbywgc2VtIHJlc3NhcmNpbWVudG8gZG9zIGRpcmVpdG9zIGF1dG9yYWlzLCBkZSBhY29yZG8gY29tIGEgTGVpIG5vIDkuNjEwLzk4LCAKbyB0ZXh0byBkZXN0YSBvYnJhLCBvYnNlcnZhbmRvIGFzIGNvbmRpw6fDtWVzIGRlIGRpc3BvbmliaWxpemHDp8OjbyByZWdpc3RyYWRhcyBubyBpdGVtIDQgZG8gCuKAnFRlcm1vIGRlIEF1dG9yaXphw6fDo28gcGFyYSBQdWJsaWNhw6fDo28gZGUgVHJhYmFsaG9zIGRlIENvbmNsdXPDo28gZGUgQ3Vyc28gZGUgR3JhZHVhw6fDo28gZSAKRXNwZWNpYWxpemHDp8OjbywgRGlzc2VydGHDp8O1ZXMgZSBUZXNlcyBubyBQb3J0YWwgZGUgSW5mb3JtYcOnw6NvIGUgbm9zIENhdMOhbG9nb3MgRWxldHLDtG5pY29zIGRvIApTaXN0ZW1hIGRlIEJpYmxpb3RlY2FzIGRhIFVURlBS4oCdLCBwYXJhIGZpbnMgZGUgbGVpdHVyYSwgaW1wcmVzc8OjbyBlL291IGRvd25sb2FkLCB2aXNhbmRvIGEgCmRpdnVsZ2HDp8OjbyBkYSBwcm9kdcOnw6NvIGNpZW50w61maWNhIGJyYXNpbGVpcmEuCgogIEFzIHZpYXMgb3JpZ2luYWlzIGUgYXNzaW5hZGFzIHBlbG8ocykgYXV0b3IoZXMpIGRvIOKAnFRlcm1vIGRlIEF1dG9yaXphw6fDo28gcGFyYSBQdWJsaWNhw6fDo28gZGUgClRyYWJhbGhvcyBkZSBDb25jbHVzw6NvIGRlIEN1cnNvIGRlIEdyYWR1YcOnw6NvIGUgRXNwZWNpYWxpemHDp8OjbywgRGlzc2VydGHDp8O1ZXMgZSBUZXNlcyBubyBQb3J0YWwgCmRlIEluZm9ybWHDp8OjbyBlIG5vcyBDYXTDoWxvZ29zIEVsZXRyw7RuaWNvcyBkbyBTaXN0ZW1hIGRlIEJpYmxpb3RlY2FzIGRhIFVURlBS4oCdIGUgZGEg4oCcRGVjbGFyYcOnw6NvIApkZSBBdXRvcmlh4oCdIGVuY29udHJhbS1zZSBhcnF1aXZhZGFzIG5hIEJpYmxpb3RlY2EgZG8gQ8OibXB1cyBubyBxdWFsIG8gdHJhYmFsaG8gZm9pIGRlZmVuZGlkby4gCk5vIGNhc28gZGUgcHVibGljYcOnw7VlcyBkZSBhdXRvcmlhIGNvbGV0aXZhIGUgbXVsdGljw6JtcHVzLCBvcyBkb2N1bWVudG9zIGZpY2Fyw6NvIHNvYiBndWFyZGEgZGEgCkJpYmxpb3RlY2EgY29tIGEgcXVhbCBvIOKAnHByaW1laXJvIGF1dG9y4oCdIHBvc3N1YSB2w61uY3Vsby4KRepositório de PublicaçõesPUBhttp://repositorio.utfpr.edu.br:8080/oai/requestopendoar:2021-01-19T06:10:07Repositório Institucional da UTFPR (da Universidade Tecnológica Federal do Paraná (RIUT)) - Universidade Tecnológica Federal do Paraná (UTFPR)false |
