It is very hard to answer your question with so many
unknowns, but I can provide my opinion.
1. Do you have any I/O requirements?? Video, audio,
etc. You need to make sure that whatever board that
you choose can handle the I/O.
2. Since you appear to be heavily involved with
mathematics, will you require high performance
floating point capability?? i.e., will you be doing
realtime FP computations??
3. Since you do not appear to be experienced, I would
suggest that 'popularity' or 'large number of users'
for the product that you select would be an advantage.
i.e., if you find 'the perfect board for your use'
and no one has ever heard of it, it will be difficult
to find reference information or assistance from
others.
4. Depending on your requirements, I would think that
one of the following might meet your needs-
DM642 EVM
6416 DSK
6713 DSK
