TMS320 ALGORITHM DEBUGGING TECHNIQUES (CONTAINS SCANNED TEXT)

As DSP tasks become increasingly complex, the ability to debug a DSP algorithm as a discrete transfer function is becoming more critical.

This report analyzes a technique for debugging a coded transfer function in a purely software environment using traditional analog troubleshooting methods applied to analyze and debug DSP algorithms using Texas Instruments (TIä). TMS320.

Topics discussed include:

- An explanation of data logging and its advantages

- How to create an input file with Lotus and save it as ASCII

- How to run your program with data logging

- How to plot output data

- Examples of highly complex algorithms.

Accompanying the text are:

- Diagrams of DSP code division

- Sample input text editor file

- Spread sheet calculations of sine waves

- Lotus command structures

- Sample four Op-Amp block diagram

- Example of a four second-order IIR structure.
