I also bought on of these and I was a bit disappointed. The memory is really
 limited
and the instruction set of the c25/26 is, in my opinion, terrible. However,
 texas has
a new DSK with a c3x on it and that is a much nicer chip. (32 bit and floating
point). Also Analog Devices has a DSK for one of their chips with 32K on chip
 ram
and stereo AD at 48 KHz for $89.   More info at:

I agree to a certain extent. Like I said, it had the power to do a lot of neat
stuff, and was great for learning some DSP. I worked on signal processing for
amateur radio applications, and this chip is fairly common in ham radio
commercial boxes. If I remember correctly, the Analog Devices chips had a much
nicer instruction set, that was easier to use and let the programmer more
easilly exploit the abilities of the processor.

I worked on a couple of Motorola DSP chips, I don't even remember which ones,
both 16 bit fixed point, one with a Codec with a comb filter on the input. The
instruction for those was OK, but I would have preferred the Analog Devices
chips.

I'm sure there's a lot better DSKs available now, as it's been a few years since
I bought mine. Pelle's right, the x30 is a neat chip...
