Since extensible processing platforms combine a high-performance processing system and reconfigurable logic on the same microchip, they are chosen for design space exploration and evaluation of different types of software/hardware partitioning. It is shown that reconfigurable logic is more preferable for concurrent execution of lower level application-specific operations over vectors such as Hamming weight computation, test for orthogonality/intersection, and the majority of bitwise operations. Higher level procedures mainly involving sequential processing of matrices are more efficient for implementation in software running on embedded processor. Two problems from the scope of the Boolean satisfiability were taken as a case study. All the proposed solutions were modeled in software and then were implemented, tested, and evaluated in Zynq xc7z020 microchip.","PeriodicalId":103316,"journal":{"name":"MELECON 2014 - 2014 17th IEEE Mediterranean Electrotechnical Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130279530","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}

Cognitive Radio (CR) technology is introduced as a solution to allow secondary (unlicensed) users to utilize the available frequency bands that are unutilized by primary (licensed) users. This feature, offered to CR users, has shown great potential for enhancing the performance of wireless networks and meeting the demands of future generation wireless applications. However, using this technology will impose several challenges influence the performance of the primary network. In this paper, the queuing system delay is studied, and a dynamic channel allocation technique for CR networks is presented. Based on multi-channel and time slotted scenario, the proposed scheme determines the optimal channel for spectrum switching. Moreover, in this paper, we discuss the interference problem caused by a simultaneous transmission of CR users and primary users. The large message segmentation subject to collision constraints is also investigated in this work. The simulation results have shown that the average delay can be reduced using the M/D/1 queuing model, which can improve the CR network performance. The proposed model is then used to evaluate the effects of the number of channels and channel utilization on the network performance.","PeriodicalId":103316,"journal":{"name":"MELECON 2014 - 2014 17th IEEE Mediterranean Electrotechnical Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131218351","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}
