Title (EN) SYSTEM AND METHOD FOR PROCESSING READ REQUEST
(FR) SYSTÈME DE TRAITEMENT D'UNE DEMANDE LUE
Abstract: front page image
(EN)A system for processing a read request for maximizing host read performance in a flash memory-based storage device is provided. The system for processing the read request solves a bottleneck phenomenon caused by a processor by adding an independent automatic read request processor, different from a conventional system in which a processor of a storage device processes the read request. Also, when processing the read request, a storage device using a write buffer may control a process of merging data of the write buffer and a flash memory and transmitting the data to a host based on a descriptor array, thereby minimizing processor overhead.
(FR)L'invention porte sur un système de traitement d'une demande lue en vue de la maximisation de la performance de lecture d'un l'hôte dans un dispositif de stockage à base de mémoire flash. Le système de traitement des demandes lues résout le phénomène de goulot d'étranglement causé par un processeur en lui ajoutant un processeur automatique indépendant de demandes lues, différent du système conventionnel dans lequel le processeur d'un dispositif de stockage traite les demandes lues. De plus, lors du traitement d'une demande lue, un dispositif de stockage utilise un tampon d'écriture gérant le processus de fusion des données du tampon d'écriture ainsi qu'une mémoire flash, puis transmet les données à un hôte sur la base d'un réseau descripteur, ce qui minimise les surcharges du processeur.
