    摘要: A CAM system (200) can include a number of entries (202-0 to 202-3) having one portion for storing a data value (e.g., E1) and another portion for storing a replicated data value (E1(REP)). For on-the-fly error correction, the entries can be searched by applying an appended key value that includes a key portion (KEY) and replicated key portion (KEY(REP)).

    摘要: An Internet-coupled transaction service has a link to a computer appliance coupled to a merchant site, the computer appliance operated by a person who has selected one or more products or services to purchase at the merchant site, and who has selected, through the merchant site, the transaction service to arrange payment, and software executing from a computer-readable medium accessible to the service. The transaction service, via the software verifies the identity of the person, determines a credit worthiness for the person, and the score being sufficient, arranges payment to be made to the merchant on behalf of the person, and arranges repayment terms with the person for the payment to the merchant.

    摘要: An improved architecture for a network search engine (NSE) is disclosed herein as including an interface manager, one or more levels of a splitting engine, an array of data processing units (DPUs), and a cascade block. A method for using the improved NSE architecture to form an efficient pointer entry database is also provided. As described herein, the improved NSE architecture simultaneously provides high speed, search throughput, update rate and capacity, coupled with low power and fixed latency searches for all search key widths.

    摘要: An integrated circuit device for processing an access control list. The integrated circuit device includes a first content addressable memory (CAM) including a plurality of CAM blocks to generate respective match indices, each match index indicating a storage location within the corresponding CAM block of an entry that matches a search key. The integrated circuit device further includes a plurality of memory arrays to receive the match indices from the CAM blocks and to output respective lookup values from storage locations indicated by the match indices, each lookup value including information that indicates an action to be taken with respect to a packet used to obtain the search key and information that indicates a priority of the action relative to actions indicated by information in others of the lookup values.
