Digital Signal Processing and Applications with the OMAP - L138 eXperimenter

This is the most comprehensive text available on hands-on teaching of Digital Signal Processing, and the first book to feature the new floating point DSP development system to be promoted by the Texas Instruments University Program: the OMAP L138 eXperimenter and CCS v4 (which replaces the C6713DSK). Using a practical approach, the book provides a large number of real-time example programs that use actual input and output signals and give visible and audible results. It is an excellent teaching aid for professors wishing to teach DSP via laboratory experiments and for students or engineers wishing to study DSP using the inexpensive OMAP L138 eXperimenter.

Teaches digital signal processing concepts via hands-on examples The OMAP-L138 eXperimenter is the latest inexpensive DSP development system to be adopted by the Texas Instruments University Program. The OMAP-L138 processor contains both ARM and DSP cores and is aimed at portable and mobile multimedia applications. This book concentrates on the demonstration of real-time DSP algorithms implemented on its C6748 DSP core. Digital Signal Processing and Applications with the OMAP-L138 eXperimenter provides an extensive and comprehensive set of program examples to aid instructors in teaching DSP in a laboratory using audio frequency signals--making it an ideal text for DSP courses at senior undergraduate and postgraduate levels. Subjects covered include polling-based, interrupt-based, and DMA-based I/O methods, and how real-time programs may be run using the board support library (BSL), the DSP/BIOS real-time operating system, or the DSP/BIOS Platform Support Package. Chapters include: Analog input and output with the OMAP-L138 eXperimenter Finite impulse response filters Infinite impulse response filters Fast Fourier transform Adaptive filters DSP/BIOS and platform support package Each chapter begins with a review of background theory and then presents a number of real-time program examples to reinforce understanding of that theory and to demonstrate the use of the OMAP-L138 eXperimenter and Texas Instruments Code Composer Studio integrated development environment.
