Well the big problem is that it assumes a FPU, sends the instructions
to the FPU (which is does have but isn't supported by default), those
instructions fail, causing the kernel to have to re-issue instructions
to emulate a FPU. This whole thing takes _forever_, if the distro was
built with softfloat it wouldn't be as bad, and if built with Mavric
Crunch would be even better. You can of course, rebuild the distro
with EABI or softfloat if you want, there's a few people on here
working on that.

Yeah, it uses floats all over the place. Interesting,
that would explain why I had to fall back to a two
year old version of the app (less use of floats).
So the processor emulates FP math? How can I get the
FPU to work?
Thanks,

Check that it doesn't use floating point math.
If it does, you are in trouble. You could try
getting the FPU on the
ARM9 to work, but that won't be easy.

Hi folks,
I've been working getting an audio app
(www.rtcmix.org) to compile for
the TS-7xx boards. I think I've finally got it
working, using the
ALSA libraries, etc... I can definitely play
soundfiles through my
little USB dongle.
I'm noticing, however, that for basic synthesis
(eg., making a sine
wave) the board is far too slow). I mean, I can
barely get one
oscillator going.
I used to be able to get about a dozen or so on my
old 90 mhz Pentium.
What's the deal with the ARM processor and speed?
Thanks,
DT
