getting armed (was: Re: Raspberry pi )

Yeah, just gotta take in all the info. FWIW, my observations so far:

Embedded dsp is just a *complete* waste of space. The point about ARM is it creates a critical mass of sharable HLL code (huge amounts, millions of lines) that run on hardware from competing chip manufacturers.

The r-pi uses an ARM core that's slightly out of date, using a subset of latest instructions, hence low cost (possibly runs a bit faster with the reduced silicon complexity).

At a guess, r-pi is a bit underpowered for even basic sc, but i'm not sure about this.
However, that will change.
