Hello,

you can rely on choice which IPP dispatcher will do for you. When you link with IPP DLLs dispatcher will work automatically and will choose the best suitable version of processor-specific code. When you link with IPP static libraries, you need to call ippStaticInit function before the first call of any other IPP function. This will initiate IPP static dispatcher, which again will do the best choice automatically. You can change this choice with call of ippStaticInitCpu function, where you can specify which exactly processor-specific code you want to run.

Regards,
Vladimir
