ippiResizeSuper_8u_C1R/C3R avx & avx2 performance

Heng_L_

Hello,

We are using IPP to speed up image resizing. However, according to our test, AVX2 does not have any performance gains compared to either AVX or SSE4.2

the functions we are relying on is ippiResizeSuper_8u_C1R/ippiResizeSuper_8u_C3R and the other related functions. I did notice that, according to http://software.intel.com/en-us/articles/haswell-support-in-intel-ipp none of the resize functions appear to have haswell specific optimization.

can we expect this to change in future IPP versions? if so, will they be in next version/update of IPP? or AVX2 won't help for these resize functions?

thanks

Hi Heng,

AVX/AVX2 optimization for ippiResizeSuper is available starting from IPP 8.0.

what kind of performance improvement you think we could expect by going from SSE4.2 to AVX2?

none of the resize functions are listed in http://software.intel.com/en-us/articles/haswell-support-in-intel-ipp

is there somewhere else we can check to see whether some functions have AVX/AVX2 specific optimization? thanks

Heng,

a performance improvement depends on many factors, the best way to check performance is to apply AVX/AVX2 optimized ippiResizeSuper function to your application.
