I agree about ARM assembly, I have written some (not DSP related) many

Does this ARM chip have real fixedpoint hardware, or do you have to do bit
manipulations to get the numbers?

Writing DSP
code for integer platforms is extremly tedious,
Having done a lot of it (fixed point, on ARM), I'd disagree. But It is
certainly different. If you want good fixed point performance, you have
to write some of the inner loops in assembly. Not that this is a problem
- ARM assembly is a pure pleasure compared to Intel. And there a lots of
little computation that can be expressed more easily in assembler than
in C/C++.
