Hi people, i've just released this
https://github.com/npisanti/ofxSIMDFloats
it's an addon for allocating memory-aligned arrays of floats and make operation on them using the SIMD instructions present in your cpu (SSE2 for x86 and NEON for ARM). I hope someone of you will find it useful when an extra performance boost is needed =)
let me know if there are some issues / questions
