A method and apparatus are disclosed for providing a DMA process. Accordingly, a DMA process is initiated for moving data from contiguous first locations to contiguous second locations and to a third location or third locations. Within the DMA process the data from each of the contiguous first locations is retrieved and stored in a corresponding one of the contiguous second locations and in the third location or corresponding one of the third locations. The DMA process is performed absent retrieving the same data a second other time prior to storing of same within the corresponding one of the contiguous second locations and in the third location or corresponding one of the third locations.

L'invention concerne un procédé et un appareil permettant un traitement DMA. Un processus DMA est déclenché pour le dépalcement de données de premiers emplacements contigus vers des seconds emplacement contigus et vers un ou plusieurs emplacements. Dans ce processus, les données provenant de chacun des premiers emplacements contigus sont extraites et stockées dans un des seconds empalcements contigus correspondants et dans le troisième emplacement ou un des troisième emplacements. Le troisième processus DMA est assuré the same data a second other time prior to storing of same within the corresponding one of the contiguous second locations and in the third location or corresponding one of the third locations.
