As a part of this architecture, a high-performance hardware optimized variant of the well-known Gaussian elimination over GF(2l) and its efficient implementation are presented. The resulting signature generation core of Rainbow requires 63,593 gate equivalents and signs a message in just 804 clock cycles at 67 MHz using AMI 0.35 mum CMOS technology. Thus, Rainbow provides significant performance improvements compared to RSA and ECDSA.","PeriodicalId":246715,"journal":{"name":"2008 International Conference on Application-Specific Systems, Architectures and Processors","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124957478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This phase data need to be unwrapped before it can be of use. Phase unwrapping is the process by which an integer multiple of 2pi is added to a measured, wrapped phase value in order to generate a continuous function. The algorithm used is the minimum LP norm method which uses a two dimensional discrete cosine transform (2-D DCT) which forms the most computationally expensive part of the minimum LP norm method. This paper presents an implementation on reconfigurable hardware that performs the 2-D DCT over the entire 1024 times 512 image, solves the intermediate equation and then performs the two dimensional Inverse discrete cosine transform (2-D IDCT) using a novel FPGA implementation of the DCT with a semi-floating point data representation. This represents the largest 2-D DCT FPGA implementation in the literature, with most previous work focusing on the 8 times 8 transform.","PeriodicalId":246715,"journal":{"name":"2008 International Conference on Application-Specific Systems, Architectures and Processors","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115561673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
