I still find myself fighting denormalization in my code.
P.S.: I filed a request to ADC for a tech paper about
Denormalization on the Mac several months ago. Still nothing except
a "be patient"-reply.
You probably should read this :
http://www.musicdsp.org/files/denormal.pdf
It has been made by one guy of our dev team, it does not use non-IEEE
mode, and all solutions are exposed. We have been using those methods
for all our plugin here at ohmforce and it has always worked
perfectly *without any asm*.
I hope this will help you. Keep me posted if you want some more info
from that guy himself.
He he,
I currently use one of these methods, but I want to get rid of them
since the PPC _can_ be set to non-IEEE mode. I just don't know how to
set the registers appropriately :-)
It is a very good reading, anyway.
However, I have lots of small buffers to deal with in my AudioUnits,
and due to modular architecture, I will add a small AC at Nyquist
several times to prevent the cpu from going mad. Not needing to do
this would save many cycles :-)
Cheers,
;) Urs
