WebDec 6, 2007 · Hi, I did some performance comparisons, used Intel C++ compiler 9.1 for Windows. ippsCopy_32s vs. memcpy: exactly the same speed. ippsConvert_16s32f is slower than the standard C type cast (float) in a loop. The ipps_zlib is slower than a standard zlib library. Do you have an explanation for this...
