VARIABLE ACKNOWLEDGE RATE TO REDUCE BUS CONTENTION IN PRESENCE OF COMMUNICATION ERRORS
(FR)
TAUX D'ACCUSÉ DE RÉCEPTION VARIABLE POUR RÉDUIRE UN CONFLIT D'ACCÈS AU BUS EN PRÉSENCE D'ERREURS DE COMMUNICATION
Abstract:
(EN)
A variable write back indicator control is provided to control the amount of data to be re- transmitted when a packet error occurs. A hardware controller obtains an indication that an acknowledge rate or an amount of set write back indicators of a data frame is to be adjusted. The indication is based on an error rate of data transmission over a communication bus. Based on obtaining the indication that the amount of set write back indicators is to be adjusted, one or more write back indicators are adjusted.
(FR)
Un indicateur d'écriture différée variable de commande est conçu pour commander la quantité de données devant être re-transmise lorsqu'une erreur de paquet se produit. Une unité de commande de matériel obtient une indication qu'un taux d'accusé de réception ou une quantité d'ensemble d'indicateurs d'écriture différée d'une trame de données doit être ajustée. L'indication est basée sur un taux d'erreur de transmission via un bus de communication. Sur la base de l'obtention de l'indication que la quantité d'ensemble d'indicateurs d'écriture différée doit être ajustée, un ou plusieurs indicateurs d'écriture différée sont ajustés.
