Utveckling av projektlaborationför signalbehandling: med digital signalprocessor programmeradmed LabVIEW och Matlab
Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
This report describes how to process audio signals in real time with a digital signalprocessor. The digital signal processor used in the thesis and described in the reportare the Blackfin processor ADSP-BF537 from Analog Devices.
In the body of this report there is theory of the processor characteristics and thevarious programming languages used. All experiments that were made on theprocessor are described, these descriptions also help in understanding the annexeswhere the experiments will be presented. The body of this report also describes theprogram used to do experiments. Testing the CPU limit was done and the results arepresented to get a good view of what it can handle. The tests were ruling the use forwhich the processor will be used in the course of signal processing. A Introductionlaboration going through settings on the processor and a simple signal processingapplications is described. The guide is also attached to the end of the report (seeAnnex 1 for Introduktionslaboration i LabVIEW, page 20). Implementation of the labare done with both LabVIEW and Matlab on the processor. This was tested to seewhich program was most appropriate to use. The pros and cons of both programsare described.
The final section of the report mentioned observations of the problems encounteredand suggestions for how to proceed in the future. Options other than the processorused in this thesis are mentioned and described. References to information sourceson the Internet were information was gathered and used to program the processor isindicated. Finally the report ends with appendices, where each step is described in theexperiments that was implemented on the processor. Even more specific informationabout how everything will be implemented in the programs are described and theadvantages and disadvantages they have.
