Hi,

will the GTA03 have a FPU?

The reason I'm wondering is because of, well, it sucks if it doesn't.. We
all
want to run all available standard Linux apps on this thing, but many
applications
_require_ floating point math, especially for graphics! I've been working
a lot (a lot meaning, whenever I don't have to take care of my "real" job,
and
my family.. :-P) on my program "SATAN" and I got pretty good performance
out of it now.. The problem though is that it is GTK- and Cairo-based and
that
these libraries use floats quite extensively.. This really hurts performance
on the OpenMoko and makes the application feel really sluggish when you
want to interact with the GUI. I haven't done any real benchmarks, but I do
know that the floating point version of SATAN is totally UNUSABLE on the
OpenMoko, but the fixed-point math version works "OK" (except the GUI
then..).

   Best regards
     Anton
