I am concerned if the TMS320F28335 as a whole can handle speex:
16 bits, 150MHz, dual MAC, floating point
512kbytes Flash, 68kbytes RAM, with DMA
Digikey $26/100 to $30/1, not available, Mouser same$, available

Or even the TMS320F28235:
almost the same, no floating point, $3 less

Tools $500, starter kit not available

It is a very interesting *all-in-one solution*...

thanks for any comment,
Alain
