  • Patent number: 7685254
    Abstract: A runtime adaptable search processor is disclosed. The search processor provides high speed content search capability to meet the performance need of network line rates growing to 1 Gbps, 10 Gbps and higher. The search processor provides a unique combination of NFA and DFA based search engines that can process incoming data in parallel to perform the search against the specific rules programmed in the search engines. The processor architecture also provides capabilities to transport and process Internet Protocol (IP) packets from Layer 2 through transport protocol layer and may also provide packet inspection through Layer 7. Further, a runtime adaptable processor is coupled to the protocol processing hardware and may be dynamically adapted to perform hardware tasks as per the needs of the network traffic being sent or received and/or the policies programmed or services or applications being supported.

  • Publication number: 20090049230
    Abstract: Memory architecture provides capabilities for high performance content search. The architecture creates an innovative memory that can be programmed with content search rules which are used by the memory to evaluate presented content for matching with the programmed rules. When the content being searched matches any of the rules programmed in the Programmable Intelligent Search Memory (PRISM) action(s) associated with the matched rule(s) are taken. Content search rules comprise of regular expressions which are converted to finite state automata (FSA) and then programmed in PRISM for evaluating content with the search rules. PRISM architecture comprises of a plurality of programmable PRISM Search Engines (PSE) organized in PRISM memory clusters that are used simultaneously to search content presented to PRISM. A context switching architecture enables transitioning of PSE states between different input contexts.

  • Publication number: 20090045773
    Abstract: A system of energy storage and charging usable in vehicles and other applications that eliminate the battery capacity and automotive range issues is described. In our invention, vehicles are equipped with charging mechanisms to charge and recharge onboard batteries using wireless electricity and power transmission using magnetic resonant coupling between tuned electromagnetic circuits. The batteries may be charged using wireless charging systems installed along the roads while the vehicle is in use on the road. Charging system may optionally utilize infrared laser beam radiation to transmit power for charging the batteries on board a vehicle while it is in use as well. The onboard vehicle batteries may also be charged when the vehicle is not being driven either by plugging in the vehicle into wall electricity using wired power connection or may be wirelessly charged using the magnetic resonant coupling.
