It seems a shame to drop use of the DSP. It may be generally hard to program
well, but even off-loading some parts (of otherwise ARM code) to the DSP will
free up the ARM CPU to do more.

Add to this the interest involved in hacking/writing code for the DSP and this
is something I certainly want to pursue.

As a final point, if the hardware is there, don't you find it frustrating not
being able to use it? DSP, IVA, 2D/3D acceleration - all just sat there waiting
to be exploited (if we can find out how to do so)!

It would just be nice if the DSP learning curve could be made a little less
steep (and less opaque). With that said I'll keep fiddling with the DSP tools in
the hope I find the right combination.
