The dynamic parameters are the SIgnal-to-Noise And Distortion (SINAD) ratio, Effective Number Of Bits (ENOB), Total Harmonic Distortion (THD) ratio, and Spurious Free Dynamic Range (SFDR) ratio. These parameters are estimated by both frequency-domain and time-domain methods. In the former approach the estimates are those returned by the MultiFFT test available in the ADCPro evaluation software of the ADS1258EVM-PDK kit or Interpolated Discrete Fourier Transform (IpDFT) algorithm. Conversely, in the latter approach the parameters are estimated by the Multi-Harmonic Sine-Fitting (MHSF) algorithm. The IpDFT and MHSF algorithms are applied to the data acquired by the ADS1258EVM-PDK and are implemented in MATLAB. Moreover, several experimental results achieved by both approaches are carried out and then are compared each other.","PeriodicalId":230360,"journal":{"name":"2014 6th European Embedded Design in Education and Research Conference (EDERC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127196080","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}

Yet often there exists a disconnection between the rapid prototyping tools that are taught within the laboratory to demonstrate concepts and those that are used for actual deployment in a stand-alone product. This calls for an approach whereby students are exposed to multiple levels of abstraction, in order to align the skill sets of our students with the requirements and expectations of industry. This paper describes the development of a senior level undergraduate course that introduces machine vision and image processing algorithms and implementation topics within the larger context of embedded computing. The key focus is that the student appreciates the theoretical concepts but is also capable of implementing them on embedded processors for prototyping or production.","PeriodicalId":230360,"journal":{"name":"2014 6th European Embedded Design in Education and Research Conference (EDERC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121887022","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}

Different NN architectures and several optimization solutions were studied to investigate the best approach in terms of computational efficiency, memory footprint and prediction accuracy.

The application reads data from the AM335x SK's accelerometer, displays the three axes acceleration data on a Qt widget and determines the orientation of the AM335x SK (one of the six possible) as a function of the values of the three accelerations. This orientation is displayed in real-time on another Qt widget. Also, the Qt application sends the current orientation of the system to a MSP430G2553 microcontroller via Bluetooth, to be displayed on a 2×16 LCD. For this communication, the Bluetooth module of the AM335x SK is used, while MSP430G2553 is supplied with a HC05 module. Some buttons which allows the starting or the ending of the entire application or only the Bluetooth communication part are included in the window of the Qt application.","PeriodicalId":230360,"journal":{"name":"2014 6th European Embedded Design in Education and Research Conference (EDERC)","volume":"165 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124615443","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 functionalities of this scalable framework cover memory and time analysis, as well as automatic deadlock-free code generation.
