Abstract

Old Tricks for a New Dog: An Innovative Software Tool for Teaching Real- Time DSP on a New Hardware PlatformReal-time digital signal processing (DSP) is a challenging topic for many students. In order tohelp students successfully transition from theory to real-time practice, there needs to be aninfrastructure in place to support them and target as many modes of learning as are reasonablypossible. One very important segment of this needed infrastructure is a tool to support facultydemonstrations, student experimentation, and student self-learning. Professional-grade toolssuch as Texas Instruments (TI) Code Composer Studio are usually considered too complex tolend themselves easily to this pursuit. To overcome this difficulty, the authors developed asoftware package with an easy to use graphical user interface that is specifically tailored forteaching real-time DSP on inexpensive DSP starter kit (DSK) hardware by Texas Instruments.This package has evolved over the years, and has been described at earlier stages of developmentat previous ASEE conferences; previous versions are being used at many universities around theworld. The original version, called winDSK, was designed for the TI C31 DSK. It was expandedand targeted to the more powerful TI C6711 DSK (and renamed winDSK6), then later modifiedto also target the even faster and more capable TI C6713 DSK. As we gained experience withthe tool and obtained feedback from ASEE audiences, more capabilities were added over theyears that allowed more effective teaching of additional DSP topics. Recently, TexasInstruments introduced a new, inexpensive hardware platform that represents a huge step up incapability and complexity for teaching real-time DSP. This platform is the OMAP-L138, whichcontains a multi-core device that includes both an ARM926 general purpose processor and aC6748 digital signal processor. Without an easy to use tool such as winDSK6, it would beextremely difficult for educators to take advantage of this new platform, but expandingwinDSK6 to include this new hardware target is no trivial task. This paper describes the resultsof creating a new version called winDSK8 that can operate seamlessly with the new OMAP-L138 hardware platform, providing the same easy to use graphical user interface that isspecifically tailored for teaching real-time DSP, for which previous versions of winDSK werewell known. A description of teaching examples using this new hardware/software combinationwill be included.
