Algorithmes CORDIC dans Simulink

Opérations d'algorithmes CORDIC dans Simulink^®

Les algorithmes qui s’appuient sur CORDIC (COordinate Rotation DIgital Computer) comptent parmi les algorithmes les plus efficaces au niveau hardware, car ils nécessitent uniquement des opérations itératives de décalage et d'ajout. Avec l'algorithme CORDIC, il n’est plus nécessaire d'utiliser des multiplicateurs explicites. Il permet en outre de calculer un grand nombre de fonctions.
