Usually DSP starter kits and evaluation modules are equipped with audio
and/or video codecs only, but some of them also have an expansion connector
which allows interfacing to different ADC or DAC evaluation boards. In most
cases the additional interface card is needed for this. So with a two or
three boards you can build a complete acquisition system. The list of
compatible AFE boards is here:

TI also has several daughter boards for medical applications (for example,
http://focus.ti.com/docs/toolsw/folders/print/tmdxmdkek1258.html) that are
compatible with C5505 DSP evaluation module, but it seems that they don't
fit your requirements because of the low bandwidth.

However I'm not an expert in TI product line and could have missed
something. You'd better call your local TI representatives and ask them.

I understand you.
But the question is not which DSP, but which DSK.
The real question is: with which DSK from Texas will be easier to work
with any kind of biomedical signals (EMG, EEG, ECG, EOG or even MMG) with
at least 4 channels?

I said that I do not know the application requirements yet, so I was
thinking about choosing a DSP with high performance.

Thank you,

If you don't know what are you going to do, then it doesn't matter which DSP to use. Stick with the PIC. Vladimir Vassilevsky DSP and Mixed Signal Design Consultant http://www.abvolt.com

Searching for a DSK at the Texas site, I've noticed that some kits are
available with audio ports and audio codecs, while some DSPs are used
mainly for video applications. I'd like to use a DSK that is less "guided".
Any suggestions? My application processing requirements are not defined
yet, but the signal must be sampled at least at 10kHz.

Thank you,
