For example the NMEA sentence parser and 2 12-bit A/D converters


So that would make it useful when doing some geo-math on coordinates (e.g. distance to some point calculation involves gonio)
or for analog sensors that need some math formula applied e.g. thermistors that need some 3rd degree non linear formula.
or an FFT on 2 audio channels or ...

IN short as a preprocessor before sending the data to a duino.

Yes,  but I don't think it is very easy to organise it as a preprocessor between some device
and the arduino.   Unless you had two arduinos,   and one of them was there just
to manage the input and output of this device.

If it can do large FFT's the time saved may justify the communication overhead. If it can be programmed with user code, then it could be left alone for a while doing an expensive task of any kind.

Why not? OK maybe for some,  but the FPU has autonomous inputs serial?

Well I read the instructions several times and it didn't seem very clear to me.  Perhaps I should
actually obtain one and get it to work.
