IMPLEMENTING A REAL-TIME APPLICATION ON A TMS320C40 MULTI-DSP

This application report describes a method for real-time processing of images captured using a CCD (charge-coupled device) video camera using the Texas Instruments (TITM) TMS320C4x digital signal processor (DSP).

The TI TMS320C4x is one of five generations of digital signal processors in the TI TMS320 family. The parallel processing ability of the TI TMS320C4x supplies the necessary performance for the computations in this study.

The SynDEx programming environment takes advantage of the capabilities of the TMS320C4x and monitors its time behavior.

Wavelet transform theory is used for convolution of the input image with the system response. The algorithm includes a method for edge detection and determining local maxima.

Hardware used in this study includes a PC, a CCD video camera, and the HEPC2-M card serving as the motherboard for up to four TI modules. The card is configured with one HET40SDX module and one HETVIO module.
