If I use the w7_* functions only (P4 optimized) can you confirm me that when runing on a higher processor (Intel Core 2Duo) it will run and most precisely it will still use the SSE2 (P4) optimization ?
Basically,are w7_* functions faster thanpx_* functions on Intel Core2 Duo ?
that's correct, if you use P4 specific functions, it will run on all compatible processors. Please let us know if you find that W7 code is faster than V8 (Core2 specific) for some functions. That should be considered as anoptimization issue because we provide Core2 specific library which should be tuned to run most optimally on Core2 processors.
