In this paper, these inputs signals <em>e</em>(.) and <em>e̊</em> (.) are modified respectively to <em>e<sub>m</sub></em> (.) and <em>e̊</em><em><sub>m</sub></em> (.), where <em>e<sub>m</sub></em> (.) is given by <em>e</em>(.) + <em>k<sub>m</sub></em><em>e̊</em> (.) and <em>k<sub>m</sub></em> is a constant. This modification enables the performance of the overall system to be further improved through a proper choice of <em>k<sub>m</sub></em> . Moreover, the proposed scheme is simple and easy to implement as the number of signal to be measured remains unchanged after the modification. A non-linear power system is first chosen to demonstrate the effectiveness of the proposed scheme through simulations. The proposed scheme is specifically applied to enhance the damping of the mechanical mode oscillation of this non-linear power system. A real-time experimental study which involves the control of a servomotor is then performed.</p></div>","PeriodicalId":100806,"journal":{"name":"Journal of Microcomputer Applications","volume":"17 4","pages":"Pages 369-379"},"PeriodicalIF":0.0,"publicationDate":"1994-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1006/jmca.1994.1025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71736185","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 DOP architecture is designed to support efficiently high-level programming languages (HLLs) such as C or Pascal, but still be simple enough to be implemented on one field programmable gate array (FPGA). Special attention is paid to the analysis of HLL requirements on processors. The DOP is designed to be used as a building block (cell) in a FPGA library. Its simplicity allows other microcomputer functional units to be implemented on the same FPGA. The DOP serves as a core for simple solutions using currently available technology.","PeriodicalId":100806,"journal":{"name":"Journal of Microcomputer Applications","volume":"370 1","pages":"239-253"},"PeriodicalIF":0.0,"publicationDate":"1994-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82740662","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 approach is based on the observation that the data records in secondary storage have some inherent redundancy of information. This redundancy cannot precisely be predicted as in the case of typical error correction scheme's artificial redundancy. However, the redundancy can be exploited to provide error correction with some degree of confidence. We use simple and weighted checksum schemes for error detection and present algorithms for single and multiple error correction using statistical error location and correction (SELAC). An implementation of SELAC will be described with an elaborate study of its error-correction capabilities. A conspicuous aspect of SELAC is that it will not cost any processor time and storage overhead until after an error is encountered, unlike the classical schemes using single error correcting-double error detecting (SEC-DED) and double error correcting-triple error detecting (DEC-TED) codes.</p></div>","PeriodicalId":100806,"journal":{"name":"Journal of Microcomputer Applications","volume":"17 3","pages":"Pages 255-271"},"PeriodicalIF":0.0,"publicationDate":"1994-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1006/jmca.1994.1016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71740298","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}
