  • Patent number: 10216535
    Abstract: Examples of efficient MAC address storage are described, including methods and an apparatus. A method may involve obtaining a plurality of identifications associated with one or more applications executed on a computing apparatus, with each identification of the plurality of identifications different from one another. The method may also involve storing an identification entry representative of the plurality of identifications associated with the one or more applications. The identification entry may require an amount of memory space for storage less than an amount of memory space required to store the plurality of identifications associated with the one or more applications. The plurality of identifications may be a plurality of MAC addresses. The one or more applications may be one or more virtual machines.

  • Patent number: 9654397
    Abstract: A network device is provided. The network device includes: a hash memory and a controller. The hash memory has a plurality of hash tables, wherein each hash table includes a plurality of entries, and each entry in each hash table has a signature field, and a key field. The controller is configured to map a search key to a plurality of entries of the hash tables and perform longest prefix matching (LPM) on the search key based on the signature field and the key field of each mapped entry in the mapped hash tables.

  • Patent number: 9503996
    Abstract: The present invention provides a method and an apparatus for cell search and synchronization for subscriber stations of the Long Term Evolution (LTE) system. The invention uses primary synchronizing signal of primary synchronization code in each frame structure to establish synchronization with the base station when a subscriber station accesses the LTE network. With such synchronization between the subscriber station and the base station, control signals and transmission data may be correctly exchanged between them.

  • Publication number: 20090172504
    Abstract: The Viterbi decoder is an essential module in a communication system, in which the power and the decoding latency are restricted. In the present invention, a power efficient low latency survivor memory architecture and an operating method for the Viterbi decoder are disclosed by providing a plurality of trace-forward units, a plurality of first signal selecting units, a plurality of second signal selecting units and a third signal selecting unit to reduce the power consumption by decreasing the exchange times of contents in the trace-forward units. Thus, the present invention is suitable for use in mobile communication devices which require low power consumption.
