SIMD optimizations related to 2D computer graphics
C++ C CMake
Latest commit 5485c47 Mar 29, 2016 @kobalicek Added third part extended precision float implementation
Added trigo - a sub-project that tests vectorized trigonometric functions


This is a playground used to test SIMD optimized functions related to 2D computer graphics. It contains validation of SIMD optimized functions and benchmarks that show relative performance gain. Some experiments contain SSE3 and SSSE3 version that can be also used to compare with SSE2 baseline implementation.

The repository contains the following concepts:

  • dejpeg - SIMD optimized JPEG decoding functions (dezigzag, idct, ycbcr)
  • depng - SIMD optimized PNG reverse filter implementation (revfilter)
  • pixops - SIMD optimized low-level pixel operations (crossfade)
  • rgbhsv - SIMD optimized RGB<->HSV conversion
