DOS ain't dead

SSE in DOS -> Illegal Instruction Exception (DOSX)

posted by DOS386, 10.01.2008, 01:22

Forgot to mention that the "SSE" doesn't work ... or at least I failed to find a "good" enough PC to test:



Anyway, MMX against NOASM test:

MMX is 2 times faster. This is no evidence of usefulness of MMX at all - here MMX ASM competed against C++ mess. Rewriting the "NOASM" C++ stuff into optimized 80386 compatible ASM would possibly reduce MMX's benefit from 2 to a value dangerously close to 1
