Patent

CA 2558657

An embedded device is provided which comprises a device memory and hardware entities including a 3D graphics entity. The hardware entities are connected to the device memory, and at least some of the hardware entities perform actions involving access to and use of the device memory. A grid cell value buffer is provided, which is separate from the device memory. The buffer holds data, including buffered grid cell values. Portions of the 3D graphics entity access the buffered grid cell values in the buffer, in lieu of the portions directly accessing the grid cell values in the device memory, for per-grid processing by the portions.

L'invention concerne un dispositif intégré comprenant une mémoire et des entités matérielles, y compris une entité graphique 3D. Les entités matérielles sont connectées à la mémoire et une partie au moins de ces entités matérielles réalisent des actions impliquant un accès à la mémoire et l'utilisation de celle-ci. Un tampon de valeurs de cellules de grille est utilisé, ce tampon étant séparé de la mémoire. Le tampon conserve des données, y compris des valeurs de cellules de grille mises en tampon. Des parties de l'entité graphique 3D accèdent aux valeurs de cellules de grille mises en tampon dans le tampon au lieu d'accéder directement aux valeurs de cellules de grille dans la mémoire en vue d'un traitement par grille par ces parties.
