Génération de code SIMD
Vous pouvez générer du code SIMD pour certains algorithmes de DSP System Toolbox qui exigent des calculs intensifs pour les plateformes Intel®, et les processeurs Apple Silicon et ARM® Cortex®-A. Les intrinsèques SIMD améliorent considérablement la performance du code généré pour ces algorithmes, au point d’égaler voire de dépasser la performance de la simulation dans la plupart des cas. Le terme SIMD (Single Instruction, Multiple Data) désigne un paradigme de calcul où une instruction unique traite de multiples données. Un grand nombre de processeurs modernes disposent de capacités SIMD qui exécutent par exemple plusieurs additions ou multiplications à la fois.
