Abstract

La présente invention concerne l'accélération matérielle de système de traitement de signal afin d'afficher une image au moyen de techniques holographiques. Cette invention concerne un accélérateur matériel destiné à un système d'affichage d'image holographique, ce système d'affichage d'image étant agencé de façon à générer une image affichée utilisant une pluralité de sous trames temporelles générées de manière holographique, ces sous trames temporelles étant affichées séquentiellement dans le temps de sorte qu'elles soient perçues comme une image unique à bruit réduit, chaque sous trame étant générée de manière holographique par modulation d'un modulateur spatial de lumière avec des données holographiques de sorte que la relecture d'un hologramme défini par ces données holographiques définisse cette sous trame. Cet accélérateur matériel comprend un tampon d'entrée destiné à stocker des données image définissant l'image affichée, un tampon de sortie destiné à stocker des données holographiques d'une sous trame, au moins un module de traitement de donnée matériel couplé à ce tampon de données d'entrée et à ce tampon de données de sortie de façon à traiter ces données image afin de générer les données holographiques de cette sous trame et, un contrôleur couplé au module de traitement de données matériel de façon à commander ce module de traitement de données et fournir des données holographiques pour une pluralité des sous trames correspondant aux données image d'une seule image affichée au tampon de données sorties.
