Title (EN) MULTIPLE CYCLE SEARCH CONTENT ADDRESSABLE MEMORY
(FR) MÉMOIRE ADRESSABLE PAR LE CONTENU À RECHERCHE EN PLUSIEURS CYCLES
Abstract:
(EN) In an aspect of the disclosure, a method and an apparatus are provided. The apparatus may be a content addressable memory. The content addressable memory includes a plurality of memory sections each configured to store data. Additionally, the content addressable memory includes a comparator configured to compare the stored data in each of the plurality of memory sections with search input data. The comparison may be in a time division multiplexed fashion. The comparator may be configured to compare the stored data in each of the plurality of memory sections with search input data in a corresponding one of a plurality of memory access cycles. The content addressable memory may include a state machine configured to control when the comparator compares the stored data in each of the plurality of memory sections with search input data based on a state of the state machine.
(FR) Un aspect de l'invention concerne un procédé et un appareil. L'appareil peut être une mémoire adressable par le contenu. La mémoire adressable par le contenu comprend une pluralité de sections de mémoire, chacune de ces sections étant configurée pour mémoriser des données. De plus, la mémoire adressable par le contenu inclut un comparateur conçu pour comparer les données mémorisées dans chacune de la pluralité de sections de mémoire à des données d'entrée de recherche. La comparaison peut être effectuée de manière multiplexée dans le temps. Le comparateur peut servir à comparer les données mémorisées dans chacune des sections de mémoire à des données d'entrée de recherche dans un cycle correspondant d'une pluralité de cycles d'accès à la mémoire. La mémoire adressable par le contenu peut comporter un automate d'états destiné à assurer la commande lorsque le comparateur compare les données mémorisées dans chacune des sections de mémoire aux données d'entrée de recherche sur la base d'un état de l'automate d'états.
