I'm making an vector/matrix library for Game which utilizes SIMD unit on iPhone (3GS or later). How can I do this? I searched about this, now I know several options:

  • Accelerate framework (BLAS+LAPACK+...) from Apple (iPhone OS 4)
  • OpenMAX implementation library from ARM
  • GCC auto-vectorization feature

What's the most suitable way for vector/matrix library for game?
