  • Robust codebooks for vector quantization
    Patent number: 6807312
    Abstract: A method for data compression. An encoder receives data vectors from an original data set. The encoder uses a vector quantization codebook to encode the data vectors into encoded vectors. The codebook is constructed from a compound data set, where the compound data set includes real data vectors and artificial data vectors. The encoded vectors are indexed in the codebook and the indexes are transmitted across communication channels or transmitted to storage.
    Type: Grant
    Filed: July 13, 2001
    Date of Patent: October 19, 2004
    Assignee: Sharp Laboratories of America, Inc.
    Inventors: Renjit Tom Thomas, Shawmin Lei

  • Searching for packet identifiers
    Publication number: 20020154636
    Abstract: A method of locating packet identifiers held in respective memory locations in a memory, the method comprising receiving a plurality of packets, each packet including a packet identifier, searching said memory locations in a sequence to compare an incoming packet identifier with packet identifiers stored in the memory until a match is found, incrementing one of a set of counters associated respectively with the memory locations, said incremented counter being the one associated with the memory location where the match packet identifier is held, and reading values of each of the counters and using said values to determine the sequence in which the memory locations are searched for subsequent incoming packet identifiers.
