In this case, the use of an automated symbolic technique is a natural choice because manual derivation of scattering parameters is practically impossible, error-prone, and a fatiguing labour. Benefits of the presented symbolic approach are highlighted from the viewpoint of a microwave software tool. We exemplify our original symbolic algorithm by analyzing a four-port network that represents a microstrip cross-junction.","PeriodicalId":350740,"journal":{"name":"2007 8th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Services","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114285201","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}

To match the dimension of matrix A to the ULSA size, the partitioning of the matrix A into quasidiagonal blocks is performed. Each block contains p quasidiagonals. In order to decrease the computation time the reordering of elements of block matrices and resulting vector c is performed. The global structure of memory interface subsystem (MIS) is proposed. The MIS, located between the host and ULSA, provides corresponding data transfers to/from ULSA. Finally, the performance of synthesized ULSA is discussed and compared with fixed size bidirectional systolic array.","PeriodicalId":350740,"journal":{"name":"2007 8th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Services","volume":"536 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127642667","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}
