Abstract | An apparatus and method for scheduling memory requests including receiving a plurality of requests having a type and associating each request of the received plurality of requests with a corresponding target, which is associated with one channel of a plurality of channels. The method assigning a priority to each request, assigning a utilization cost to each request based on the request's target and request type, and queueing each request of the plurality of requests for scheduling. The method selecting a first request of the received plurality of requests to be scheduled based on its priority, scheduling the first request for processing at a time when the first request utilization cost is less than or equal to a current value of a dynamic utilization counter, and debiting the dynamic utilization counter by the first request utilization cost.
Un appareil et un procédé de planification de requêtes de mémoire comprennent la réception d'une pluralité de requêtes ayant un type et l'association de chaque requête de la pluralité reçue de requêtes à une cible correspondante, qui est associée à un canal d'une pluralité de canaux. Le procédé attribue une priorité à chaque requête, attribue un coût d'utilisation à chaque requête sur la base de la cible et du type de requête de la requête, et met en file d'attente chaque requête de la pluralité de requêtes pour une planification. Le procédé sélectionne une première requête de la pluralité reçue de requêtes à planifier sur la base de sa priorité, planifie la première requête pour un traitement à un instant où le premier coût d'utilisation de requête est inférieur ou égal à une valeur actuelle d'un compteur d'utilisation dynamique, et débite le compteur d'utilisation dynamique par le premier coût d'utilisation de requête. |
