> Can someone recommend a good book on writing (assembly) vector code ? Although it's not what you asking for, you may find some examples at (look for "procedure AVXAdd"): https://github.com/joaopauloschuler/neural-api/blob/master/neural/neuralvolume.pas
In the case that you are looking for X86 SIMD, you can have a look at: https://en.wikipedia.org/wiki/Advanced_Vector_Extensions
