Oh yes, there always will be applications that are computation intense, but need neither lots of IO nor lots of internal memory. I've done a equalizer filter component in Zetex' DDFA, and it would qualify as such an application - it needs 4 cells of data and 5 cells for coefficients, and the program for a biquad filter is really small - this sort of thing easily fits into one GA144 core (maybe even stereo, i.e. two of those), and the data rate for audio data is low. Zetex' DDFA is a full custom chip, so the most competitive was to build a special-purpose CPU that was just good at biquads and mixing (I did not even consider to use a b16 for that task), but if you have to buy off-the-shelf parts, the selection process is different. I would say that a hearing aid should be a full-custom chip, because you want it to be as small as possible (so it should be a one-chip solution), and as low power as possible (i.e. the smallest possible battery). As hearing aids should be mass products (thanks to Apple for selling so many iPods ;-), a full custom chip is cost efficient. -- Bernd Paysan "If you want it done right, you have to do it yourself" http://bernd-paysan.de/
