Testbase
My medical RAW image scale processor benchmarked for Intel AVX instruction set. It was fully reprogrammed for be affected by optimization algorithm by compiler option.
Specification of benchmark
- CPU: Intel Core i7-6700 @ 4GHz (Skylake-S)
- Memory: DDR4-1066 16GB (Single channel)
- OS: Windows 7 professional 64bit
Compiler
- MinGW-W64 64bit version 4.8.0
Compiler options
- -fomit-frame-pointer
- -fexpensive-optimizations
- -O3
- -s
- -m64
- -march=corei7-avx
RAW image source
- 3072×3072, 16bit grayscale X-Ray image
Benchmark rule
- Scale each different filter for double size.
Results
Specially lanzcos 3 scale took 30% more speed at under 1 second. So I looking fore more faster way how it make faster than now. And it is almost same with B-Spline filter, or sometimes B-Spline faster than lanczos3, Hmmm …
