Re: A little help needed on code optimisation to deal with delay slots

Hi Joolz!

You have BIG problem :) 10 cycles stall every mul.
The most "multiplication consuming" functions are
- IMDCT - actually it isn't too much
- synthesis filter

last one has a lot of multiplication
all other relatively free from mult operation. May be stereo
processing has a little.

If you have short of calculation power I can recommend you to do same
as I did. I've separated calculation functions and implement them on asm.
I can send the source code of of MAD with such improvements  that I used
for
- tms320vc55xx and
- sp3R5 3DSP cores.
