Title (EN) HARDWARE ORIENTED HOST-SIDE NATIVE COMMAND QUEUING TAG MANAGEMENT
(FR) GESTION D'ETIQUETTES DE FILE D'ATTENTE DE COMMANDES NATIVES COTE HOTE ORIENTEE MATERIEL
Abstract:
(EN) Methods and apparatus for host-side Serial ATA Native Command Queuing (NCQ) tag management are disclosed. In one aspect, an exemplary apparatus may include a memory and an NCQ tag selection circuit in communication with the memory. The memory may store information for each of a plurality of different NCQ tag values. The information for each NCQ tag value may indicate whether or not a command having the NCQ tag value has been issued. The NCQ tag selection circuit may examine the information in the memory, and may select an NCQ tag value having information that indicates that a command having the NCQ tag value has not been issued. Systems and architectures including such apparatus are also disclosed.
(FR) L'invention concerne des procédés et des appareils destinés à une gestion d'étiquettes de file d'attente de commandes natives ATA en série côté hôte (NCQ). Dans un mode de réalisation, un appareil exemplaire peut comprendre une mémoire et un circuit de sélection d'étiquettes NCQ en communication avec la mémoire. Celle-ci peut stocker des informations pour chaque valeur d'une pluralité de valeurs d'étiquettes NCQ différentes. Les informations pour chaque valeur d'étiquette NCQ peuvent indiquer si une commande possédant la valeur d'étiquette NCQ a été émise ou non. Le circuit de sélection d'étiquettes NCQ peut ensuite examiner les informations dans la mémoire et peut sélectionner la valeur d'étiquette NCQ possédant les informations indiquant qu'une commande possédant la valeur d'étiquette NCQ n'a pas été émise. L'invention concerne également des systèmes et des architectures comprenant de tels appareils.
