150mhz ARM could do simple DSP, but will choke once you get math heavy.
I thought you meant more like an AVR atmega in terms of microcontroller.
A more powerful general CPU is probably the simplest thing to use.
Hardware DSPs often have non-free compilers or even their own language to
use for development.
