However, the benefit they gained are heavily offset by the slow residue-to-binary conversion due to the large modulo operations and limited number theoretic properties of arbitrary moduli. This paper presents a fast residue-to-binary (R2B) conversion method by transforming a large number of residues of arbitrary moduli into only three residues before the conversion. It exploits the smaller and parallel operations of base extension for the mapping to {2n−1, 2n, 2n +1} and the highly efficient adder-based R2B converter of the latter to achieve 2.25 ∼ 6.8 times speedup over recent R2B converters, which translates to approximately 10.2% to 32.08% of overall speed improvement for their FHE implementations.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":"33 1","pages":"9-12"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74442925","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}

Among various applications, de novo sequence assembly is a technique using NGS short reads to obtain a whole genome with no reference. To make assembly results accurate, it is a common practice to filter out low-quality data at the early stage of the assembly pipeline. Since filtering takes a great portion of assembly time, how to increase the processing speed of filtering stage becomes an important issue, especially with growing data scale in recent applications. In this paper, we propose an FPGA-based quality filter to accelerate the filtering step. With the introduction of the One-Hot-encoded accumulator and related modules, the hardware filter can reduce the processing time by half.","PeriodicalId":6495,"journal":{"name":"2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS)","volume":"18 1","pages":"139-142"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72596810","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}
