Description/Value to Others: A complete sample for development of Windows applications to control the TMS320CC31 and TMS320VC33 DSKs. A full Visual C++ project, and multiple Code Composer projects, are provided to build a fully functional example application set. With this support, students can create stand-alone DSK applications with a graphical user interface on the host PC, and be able to run them from other computers with a minimal amount of software installation. DSK applications are included using both assembly language and C programming.
Communication between the host PC and the DSK is based on the winDSK kernel, and does not require that Code Composer be installed on the host PC. Multiple parallel port configurations are supported. Requires Microsoft Visual C++ 6.0 for the host side application, and Code Composer for the DSK application. The host PC must have the Scientific Software Tools, Inc. Windows 95/NT Port I/O Driver installed.

Description/Value to Others: This course is included in the EEC curriculum of the University of Porto, is given in Portuguese language, and is dedicated to laboratory work using a TI starter kit based on the C31 floating point processor. This course assumes that students are already familiar with basic discrete time theory including such concepts and techniques as discrete time signals and systems, sampling and reconstruction of analog signals, linear time-invariant systems, structures for the realization of LTI systems, FIR and IIR filter design, decimation and interpolation, the discrete Fourier transform and Z transform, overlap-add and overlap-save methods of fast filtering in the frequency domain, response of LTI systems to discrete random signals, the FFT and its implementation.
The DSP laboratory course focuses on practical DSP applications and issues including efficient realization structures and real-time processing constraints. The motivation of the course is that the advantages of DSP are better demonstrated by lab examples covering a representative diversity of application scenarios, and that effective learning happens when the student is challenged with specific DSP design and realization issues.
Besides getting familiar with the C31 starter kit development environment plus the (unfortunately discontinued) Code Explorer debugger, students are motivated to new topics such as filter banks, uniform filter banks and their relation to the DFT, half-band filters, M-band filters, power complementary filters, the QMF filter bank and its efficient realization, multi-resolution analysis using the QMF, adaptive filtering, polyphase decomposition of interpolation and decimation filters and their efficient realization, Hilbert Transformer and SSD modulation. During a 13 week semester, students have to perform 10 laboratory experiments, most of which require Matlab and assembly programming.
The themes of those laboratory experiments are: aliasing in sampling, waveform generation and DA+AD testing, floating-point versus fixed-point processing, FIR filtering and filter modulation, IIR filtering, five-vowel synthesizer, interpolation using polyphase filters, echo cancellation, FFT assembly implementation, and SSB modulation.

A special case of the IIR filter used to identify the dual tones generated when the buttons of a touch tone telephone are pressed. Uses a microphone to pick up the sound of the telephone and shows the buttons pressed on the computer screen.
Application 8. Spectrum Analyser
Uses a Fast Fourier Transform (FFT) to analyse the power of specific bands in an audio signal.

Optionally, a signal generator to generate sine waves in the range 20 Hz to 50 kHz.
To produce quantitative results for Laboratory 9, a digital frequency meter and/or a digital storage oscilloscope are required.
Laboratory 9. Comparison of Performance of C and Assembly code
For which of the following does assembly language offer a benefit in performance over C code:
a) Finite Impulse Response (FIR) filters
b) Infinite Impulse Response (IIR) filters
c) Adaptive filters?
Does the execution time of a Fast Fourier Transform (FFT) increase linearly or logarithmically with the number of points?
Laboratory 10. Decimation by Integer Amounts to Decrease Sampling Rate
How does reducing the sampling rate affect the audio quality?
Why is an anti-aliasing filter required?
Laboratory 11. Interpolation by Integer Amounts to Increase Sampling Rate
How does increasing the sampling rate affect audio quality?
Why is an anti-imaging filter required?
Laboratory 12. Noise Reduction Using Adaptive Filters and Notch Filters
In which cases would an IIR filter be used to remove noise from an audio signal?
In which cases would an adaptive filter be used to remove noise from an audio signal?

Computer Language on which the material is based: C, Assembler, Matlab
Description of item: Laboratory course material (lab exercises and source code) for 6 labs. Experiments cover fundamental concepts of digital signal processing like sampling and aliasing, quantization in A/D conversion and in internal arithmetic operations, digital filter design and implementation, spectrum estimation and fast transforms, sampling-rate conversion and multi-rate processing. Application experiments address a selection of multi-media and digital communications problems where visual and auditory feedback is used to demonstrate the desired effects and artifacts of digital processing.
