You don't seem to truncate acc0 to 40 bits? The DSP coprocessor in
non-iWMMXt xscale cores does truncate, and some future version of Linux
(2.6.20?) might use this as a test to determine whether the CPU we're
running on is iWMMXt-capable or not:
http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=3881/2
So, are you trying to emulate the DSP coprocessor, or the
(mutually exclusive, since it uses the same instruction space)
iWMMXt coprocessor? :)
cheers,
Lennert
