| description | The invention concerns a digital data transmitting/receiving device capable of processing different rates selected from a group of predetermined rates. It comprises a coding/decoding stage including interleaving means (MET) and deinterleaving means (MDET) comprising a storage (MM) whereof the minimum size is fixed in accordance with the maximum rate of said group, and having a first memory workspace (ESM1) allocated to the interleaving means and second memory workspace (ESM2) allocated to deinterleaving means. The size of each of said two memory workspaces are parameter-adaptive according to the rate being actually processed by the device.
Le dispositif d'émission/réception de données numériques est capable de traiter des débits différents pris parmi un groupe de débits prédéterminés. Il comprend un étage de codage/décodage de canal comportant des moyens d'entrelacement (MET) et des moyens de désentrelacement (MDET) incluant une mémoire (MM) dont la taille minimale est fixée en fonction du débit maximal dudit groupe, et possédant un premier espace-mémoire (ESM1) alloué aux moyens d'entrelacement et un deuxième espace-mémoire (ESM2) alloué aux moyens de désentrelacement. La taille de chacun de ces deux espaces-mémoire est paramétrable en fonction du débit effectivement traité par le dispositif. |
