  • Patent number: 11776467
    Abstract: Disclosed herein is an LED driver chip capable of being used for master chip and slave chip. In case that the LED driver chip of the disclosure is used for the master, the strobe clock signal may be used as a reference clock signal. The 1-st to the n-th frequency clock signals, which are relatively simple to generate, may be provided as the 1-st to the n-th gray clock signals. In case that the LED driver chip of the disclosure is used for the slave, the external clock signal may be used as a reference clock signal. The 1-st to the n-th delay clock signals, which have a phase according to the reference clock signal, may be provided as the 1-st to the n-th gray clock signal. As a result, the LED driver chip of the disclosure can be used for both a master chip and a slave chip.

  • Patent number: 8667341
    Abstract: An apparatus and method for determining interleaved addresses of a turbo interleaver are disclosed. A new interleaving size of received data is compared with a previously-stored interleaving size. When the compared interleaving sizes are equal to each other, the received data is decoded using previously-stored interleaved addresses. When the compared interleaving sizes are different from each other, the received data is decoded using new interleaved addresses generated with the new interleaving size. The turbo interleaver generates interleaved addresses at minimum number of code blocks rather than every code block, resulting in reduction of decoding delay and improvement of decoding performance.

  • Patent number: 8559528
    Abstract: A method and apparatus for synchronization of a moving picture experts group (MPEG) transport stream, which minimizes an initial delay are provided. A packet synchronization unit and a mode of the packet synchronization unit to are initialized to “0”. Values of sync words are stored by shifting values of a sync word register when the sync words have been received and the received sync word is compared with predetermined code words As a result of the comparison, a determination is made as to whether a bit difference between the sync words and the predetermined code words exceeds a predetermined threshold value.

  • Publication number: 20060029167
    Abstract: An apparatus and method are provided for decoding data of first and second control channels in a mobile communication system providing multi-media services including voice and data services. The apparatus includes an input section for selectively outputting data stored in first and second control channel input sections which store data of the first and second control channels, respectively, a viterbi decoder core block for outputting a decoding result by decoding the data output from the input section, an output section for storing the decoding result output from the viterbi decoder core block in one of first and second control channel output sections, and a controller for setting a second control channel delay flag, which is a signal for delaying data decoding for the second control channel, as “on” in order to perform data decoding for the first control channel if decoding start signals of the first and second control channels are simultaneously input.
