tools/staticlib/ipp_*.h files for em64t

Arkadi — Fri, 06 Apr 2007 10:15:48 GMT

In ia32 IPP there is tools/staticlib/ipp_*.h to pull in the symbols from static libraries for specific processor only.
Are there similar .h files for em64t IPP?
Now I'm using -lemerged -lmerged and ippStaticInit() on em64t. That works fine but in case ia32 linking style is supported I would like to try it on em64t too.
In em64t libraries I see mx, m7, u8 cores. Could you point me to description of which core corresponds to which Intel CPU, and which core may (or may not) work on AMD Opterons?

Hello,

u8 libraries supports new Intel Core 2 Duo microarchitecture. m7 libraries supports previous Intel 64 architecture (also known as EM64T).

These libraries will also run on any 100% compatible processor.

Vladimir

If running on AMD CPU, the ippStaticInit() should pick the best core based or CPU features available, right?

Yes, that's correct. IPP will dispatch the optimized vcode based on processor features.
