[iiwusynth-devel] SSE

[M. Nentwig]

Hello,

I found some material on SSE:

http://x86.ddj.com/articles/sse_pt1/
http://x86.ddj.com/articles/sse_pt2/
http://x86.ddj.com/articles/sse_pt3/simd3.htm
http://courses.ece.uiuc.edu/ece291/archive/spr2002/lecture/lecture18_6pps.pdf

and the gcc manual
http://gcc.gnu.org/onlinedocs/gcc-3.2/gcc/X86-Built-in-Functions.html#X86%20Built-in%20Functions

It can really process four floats at the same time. Now think about the
4th order interpolation routine (a0*s[0]+a1*s[1]+a2*s[2]+a3*s[3])...
There was one line that worries me, though. The article says, that the
operating system has to support SSE for context switching.

Cheers

Markus
