Title (EN) COMPRESSION OF FREQUENT DATA VALUES ACROSS NARROW LINKS
(FR) COMPRESSION DE VALEURS DE DONNÉES FRÉQUENTES SUR DES LIAISONS ÉTROITES
Abstract:
(EN) Systems, apparatuses, and methods for compression of frequent data values across narrow links are disclosed. In one embodiment, a system includes a processor, a link interface unit, and a communication link. The link interface unit is configured to receive a data stream for transmission over the communication link, wherein the data stream is generated by the processor. The link interface unit determines if blocks of data of a first size from the data stream match one or more first data patterns and the link interface unit determines if blocks of data of a second size from the data stream match one or more second data patterns. The link interface unit sends, over the communication link, only blocks of data which do not match the first or second data patterns.
(FR) L'invention concerne des systèmes, des appareils et des procédés de compression de valeurs de données fréquentes sur des liaisons étroites. Dans un mode de réalisation, un système comprend un processeur, une unité d'interface de liaison et une liaison de communication. L'unité d'interface de liaison est configurée pour recevoir un flux de données destiné à une transmission sur la liaison de communication, le flux de données étant généré par le processeur. L'unité d'interface de liaison détermine si des blocs de données d'une première taille provenant du flux de données correspondent à un ou plusieurs premiers motifs de données, et l'unité d'interface de liaison détermine si des blocs de données d'une seconde taille provenant du flux de données correspondent à un ou plusieurs seconds motifs de données. L'unité d'interface de liaison envoie, sur la liaison de communication, uniquement les blocs de données qui ne correspondent pas aux premier ou second motifs de données.
