Hi all, i made some more changes to the devel_0_37 branch:
- if in d_ugen.c VECTORALIGNMENT is defined, all signal vectors will be aligned to the specified bit alignment. - coded some of the more important (and easy to do...) dsp functions for the Intel SSE instruction set: the functions include sig~, +~, -~, *~ and zeroing/copying routines. At the moment this is VC++/Windows only. The cpu usage for the FFT/pvoc example drops from about 25% to about 20% on my old PIII-800 with ugly SDRAM memory. I except an even better speed improvement for P4 with RDRAM/DDR memory.
best greetings, Thomas
