Hello all,
Hi, Andrew.
With all the recent talk of use of assembly on the PowerPC, I came

) may be coding the idct,
motion compensation and deinterlacing in assembly also.
There are already altivec implementations, but no ordinary PPC asm ones.
One other big killer on PPC is byte access. Look at
the bitstream decoding, if you manage to do only 32 bits aligned loads
from memory
BTW. Another place where you can get improved perfs is improving the memcpy's
used to blit the Xv source image to the DMA buffers in R128DMA(). Currently,
if using PCIGART, the target DMA buffers are cacheable. When using AGP,
though,
they aren't. In both cases, using FP registers to do the blit

Have you tried 3.1?
and I added some extra options to the configure script
(-mfused-madd, -mcpu=750, -mtune=750, -O9).
According to info gcc(-3.x):

I suggest trying -Os as well. Sometimes it runs fastest,
because smaller code fits in the instruction cache better.
