Thanks for testing.
I plan to rewrite dct64_MMX from new stuff with using 3dnow optimization for
using this stuff and on k6-2 too.
May be someone who has k6-2 want to test my new code? (in attach)
For testing - in new stuff you should simply modify one string in decode_MMX.s
from
call dct64_MMX
to
call dct64_MMX_3dnow
Note: this function is only partial optimized for 3dnow! I'll continue work on it in the next days.
But I'm interesting with benchmarks on k6-2 since only this cpu causes doubts for me.
