CONVERTING DATA FORMATS BETWEEN BMP AND COFF FILES FOR TMS320 DSP SIMULATION

This application report is aimed at digital signal processor (DSP) software development engineers working with image processing algorithms. The report focuses on the conversion process using data format converting utilities supporting the Texas Instruments (TIä) TMS320 (C1x/C2x/C2xx/C5x/C54x) fixed-point digital signal processor (DSP) in COFF format.

Basically, two main software tools are required to verify image processing algorithms: a DSP simulator and Windows application software. The TI TMS320 DSP simulator uses the COFF (Common Object File Format) data format. The most popular data format supported by Windows application software is BMP (Bit Map). (Displaying the image using Windows application software is the most effective way to verify image processing algorithms.)

The utilities used to convert the data format between BMP and COFF files make the algorithm verification procedure easier - converting BMP to COFF, processing the data using the DSP simulator, then converting the resulting COFF to BMP and finally displaying the processed image on screen.
