Abstract
Un système qui met en tampon une image dapplication réduit les exigences de bande passante d'accès mémoire. Limage de lapplication peut être logiquement séparée en tuiles. Une fenêtre peut établir une portion visible de limage dapplication, où la portion visible est plus petite que limage d'application. Les tuiles chevauchées par la fenêtre peuvent être mises en tampon dans un tampon avant et un tampon arrière. Les tuiles non chevauchées par la fenêtre peuvent être mises en tampon dans le tampon arrière, mais pas dans le tampon avant. Un gestionnaire de composition, ayant connaissance de la fenêtre et d'au moins deux tampons de tuiles non contigus dans le tampon avant, peut extraire la portion visible de limage d'application directement des tampons de tuiles non contigus.
