Real-Time DSP for Educators Michael Morrow University of Wisconsin-Madison Thad Welch United States Naval Academy Cameron Wright University of Wyoming Agenda ? Introduction – Motivation – DSK and Software Installation ? Building Real-Time DSP Applications – Software Organization – Building a CCStudio Talk-Through Application – FIR Filtering – Signal Generation ? Advanced Topics – DSP/BIOS? Application – HPI Daughtercard (DSP Services/Host Services) – Individual Projects ? Wrap-Up Motivation ? Do you teach or want to teach a DSP course? ? Do you use MATLAB? exercises in your courses? ? Do you assign exercises that work with actual signals (not generated in MATLAB)? ? Do you include real-time DSP demonstrations in your courses? ? Do you assign real-time projects? Real-time DSP ? It can be a real struggle to get started with real-time DSP – Lots of details come up that just aren’t an issue when programming in a workstation environment – Documentation is written for experts ? Learning curve is steep, if not vertical! – Few understandable examples are available ? Complexity is the norm – On-line and seminar style training is available directly from TI and the third party vendors – But, most of this training is not appropriate for the typical student (or educator) due to at least one of the following issues… Typical Training Issues ? Not meant for educators – Our first courses should motivate our students to learn more about real-time DSP – Much of the industry does not do sample-by- sample DSP, despite the fact that few teach anything else ? Meant for DSP experts – Expects significant familiarity with DSP system design – Intended for engineers transitioning from other DSP targets – Usually introducing the latest innovations and technologies, not fundamentals What You Can Take Away From This Workshop ? A TI TMS320C6713 DSK (and Code Composer Studio? software development suite) – Also includes some useful accessories - a microphone, headphones, audio cabl
