L’utilisation de la lumi\u00e8re pour calculer et communiquer au sein de la puce r\u00e9duit la chaleur, ce qui entra\u00eene une r\u00e9duction de plusieurs ordres de grandeur de la consommation d’\u00e9nergie par puce et des am\u00e9liorations spectaculaires de la vitesse du processeur, explique la soci\u00e9t\u00e9. Le processeur photonique IA est con\u00e7u pour r\u00e9soudre le besoin croissant de calcul pour supporter les algorithmes d’IA de nouvelle g\u00e9n\u00e9ration.<\/span><\/p>\n

\u00abLe minist\u00e8re de l’\u00c9nergie (US) estime que d’ici 2030, les technologies de l’informatique et des communications consommeront plus de 8% de l’\u00e9nergie mondiale\u00bb, d\u00e9clare Nicholas Harris, PhD, fondateur et PDG de Lightmatter. \u00ab\u00a0Les transistors, les \u00e9l\u00e9ments de base des processeurs traditionnels, ne s’am\u00e9liorent pas; ils sont tout simplement trop chauds. Construire des centres de donn\u00e9es de plus en plus grands est une voie sans issue sur la route du progr\u00e8s informatique.\u00a0\u00bb<\/span><\/p>\n

\u00abNous avons besoin d’un nouveau paradigme informatique\u00bb, d\u00e9clare Harris. \u00abLes processeurs optiques de Lightmatter sont consid\u00e9rablement plus rapides et plus \u00e9co\u00e9nerg\u00e9tiques que les processeurs traditionnels. Nous permettons simultan\u00e9ment la croissance de l’informatique et r\u00e9duisons son impact sur notre plan\u00e8te. \u00ab\u00a0<\/span><\/p>\n

Le bo\u00eetier de puces empil\u00e9es en 3D contient plus d’un milliard de transistors FinFET, des dizaines de milliers d’unit\u00e9s arithm\u00e9tiques photoniques et des centaines de convertisseurs de donn\u00e9es ultra rapides, selon la soci\u00e9t\u00e9. Le processeur photonique ex\u00e9cute des frameworks d’apprentissage automatique standard, notamment PyTorch et TensorFlow, permettant des algorithmes d’IA de pointe.<\/span><\/p>\n

Cette nouvelle architecture, selon la soci\u00e9t\u00e9, est une avanc\u00e9e massive dans le d\u00e9veloppement des processeurs photoniques. Les performances de ce processeur photonique sont pr\u00e9sent\u00e9es comme la preuve que l’approche de l’entreprise en mati\u00e8re de conception de processeurs offre des avantages \u00e9volutifs en termes de vitesse et d’efficacit\u00e9 \u00e9nerg\u00e9tique par rapport au paradigme de calcul \u00e9lectronique actuel et constitue le point de d\u00e9part d’une feuille de route de puces avec des am\u00e9liorations de performances spectaculaires.<\/span><\/p>\n
