With this, a specific way of using the estimation approach within a Genetic Algorithm was finally given.","PeriodicalId":193276,"journal":{"name":"2010 Second International Workshop on Education Technology and Computer Science","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129737741","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}

The current storage model C-tree for RSM is too complicated to develop an available sharing tool which affects the study of RSM. For simplifying and improving the Storage efficiency of RSM, this paper presents a simple storage mechanism for RSM based on container. The approach maps RSM into Object Model which use container for storing Resource Space Entities and consider the SELECT and INSERT operations as behaviors in Class. Moreover, the most advantageous features of RSM, aggregation query, can be achieved through the SELECT operation. And our work can also be used in the nested table application of RSM.","PeriodicalId":193276,"journal":{"name":"2010 Second International Workshop on Education Technology and Computer Science","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114355983","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}

First, using the embedded 18×18-bit multipliers in the FPGA device, we design a 256-bit Montgomery modular multiplier which spends 3 clock cycles to compute a modular multiplication. Second, the algorithm for Karatusba-Ofman multiplication is used to reduce the number of embedded multipliers needed. Third, to get a higher throughput rate on FPGA devices, we propose a 5-stage pipeline structure to realize the modular multiplier. At last, implemented on Altera Cyclone3 EP3C40F324C6, this modular multiplier runs at the clock rate of 30.38MHz, and performs a 256-bit Montgomery modular multiplication in 0.1µs, which is much faster than previous implementations on FPGA device.","PeriodicalId":193276,"journal":{"name":"2010 Second International Workshop on Education Technology and Computer Science","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121542313","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}
