Hi:

We are considering developing a board for voice applications, and have
narrowed down the choice of the dsp processor to TMS32031 and Motorola56001.
We are inclining towards 32031 for the following reasons: faster, both
floating and integer arithmetic, more on-chip memory, and possibly
cheaper.  We would like the chip to reasonably meet our future needs which
might include voice recognition, fax transmission etc.  I would appreciate
your input on how these two chips compare.

Also, can someone identify applications where floating point dsp processor
will be esspecially needed.

Finally, what are the advantages and disadvantages of floating point
calculations vs fixed point calculations?

Thanks.

Please email your responses (or post) to moorthy@saturn.ucsc.edu
If there is enough interest, I will summarize.

H. Moorthy
