No Problem - in uClinux, every memory is sharable - no MMU!
So I was able to do a quick speed test of the effect of shareable memory
to PIXIL and nano-X.
The result was - disappointing. Sending the call parameters via shared
memory instead of via the socket interface seems to have no much effect
on the execution speed. I assume this is because on uClinux, sheduling
time is short because of the nonexisting MMU.
So the main question is: why are some graphic operations are so slow?
We're back to the times when men were men
and wrote their own device drivers.
