It describes the basic knowledge and skills for designing high-performance low-power embedded devices whose complexity increases exponentially, as so does the effort of designing them. Relying upon an appropriate design methodology which concentrates on reuse, executable specifications, and early error detection, these complexities can be mastered. The paper bundles these topics in order to provide a good understanding of all problems involved. It shows how to go from description and verification to implementation and testing presenting two systems-on-chip for two different wireless applications based on configurable processors and custom hardware accelerators.","PeriodicalId":228594,"journal":{"name":"2010 12th Biennial Baltic Electronics Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124627460","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}

Calculation of the buoy heel (tilt angle or inclination) is based on continuous measurement of acceleration of the buoy in all three planes of movement, accomplished using a 3-axial solid state accelerometer (g-sensor) with the maximum range of ±3 g. The sensor is integrated with an Aid to Navigation (AtoN) telematics module that is subject to low power consumption requirements and size restrictions resulting in limited computational capability. Results of tests performed on operational marine buoys are presented at the end of the article.","PeriodicalId":228594,"journal":{"name":"2010 12th Biennial Baltic Electronics Conference","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123452536","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 analysis of effects of switching frequency modulation in open loop boost converter reveals that there is additional undesirable amplitude modulation of the input current of the converter. This effect distorted the spectrum of the input current, thus worsening the EMI reduction, achieved by the use of the frequency modulation. Experimental results, using sinusoidal and sawtooth modulating signals, proved the theoretical assumption, asserting that the effectiveness of EMI attenuation and the reduction of spectral asymmetry could be achieved choosing as high as possible operating frequencies and proper modulating profiles.","PeriodicalId":228594,"journal":{"name":"2010 12th Biennial Baltic Electronics Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129139416","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}
